Summary

This is the Cordova SDK of Adjust™. You can read more about Adjust™ at adjust.com.

N.B. At the moment, SDK 4.17.0 for Cordova supports Android platform version 4.0.0 and higher and iOS platform version 3.0.0 and higher.

Table of contents

Example app

There is Cordova example app inside the example-cordova directory and Ionic example app inside the example-ionic directory. In there you can check how to integrate the Adjust SDK into your app.

Basic integration

These are the minimal steps required to integrate the Adjust SDK into your Cordova project.

Get the SDK

You can get the latest version of the Adjust SDK from the npm repository or download the it from our releases page.

Add the SDK to your project

You can download our SDK directly as the plugin from npm repository. In order to do that, just execute this command in your project folder:

> cordova plugin add com.adjust.sdk
Fetching plugin "com.adjust.sdk" via npm
Installing "com.adjust.sdk" for android
Installing "com.adjust.sdk" for ios

Alternatively, if you have downloaded our SDK from the releases page, extract the archive to the folder of your choice and execute the following command in your project folder:

> cordova plugin add path_to_folder/cordova_sdk/plugin
Installing "com.adjust.sdk" for android
Installing "com.adjust.sdk" for ios

In case you are using Ionic Native, you can add our SDK from ionic-native repo:

> npm install @ionic-native/adjust --save
> ionic cordova plugin add com.adjust.sdk

Note: Adjust SDK plugin support for Ionic Native pull request is still not merged into ionic-native repository. Once that is done, adding Adjust SDK plugin via ionic-native repo described above will be enabled.

Integrate the SDK into your app

The Adjust SDK automatically registers with the Cordova events deviceready, resume and pause.

In your index.js file after you have received the deviceready event, add the following code to initialize the Adjust SDK:

var adjustConfig = new AdjustConfig("{YourAppToken}", AdjustConfig.EnvironmentSandbox);
Adjust.create(adjustConfig);

Replace {YourAppToken} with your app token. You can find this in your dashboard.

Depending on whether you build your app for testing or for production, you must set environment with one of these values:

AdjustConfig.EnvironmentSandbox
AdjustConfig.EnvironmentProduction

Important: This value should be set to AdjustConfig.EnvironmentSandbox if and only if you or someone else is testing your app. Make sure to set the environment to AdjustConfig.EnvironmentProduction just before you publish the app. Set it back to AdjustConfig.EnvironmentSandbox when you start developing and testing it again.

We use this environment to distinguish between real traffic and test traffic from test devices. It is very important that you keep this value meaningful at all times! This is especially important if you are tracking revenue.

Adjust logging

You can increase or decrease the amount of logs you see in tests by calling setLogLevel on your AdjustConfig instance with one of the following parameters:

adjustConfig.setLogLevel(AdjustConfig.LogLevelVerbose);   // enable all logging
adjustConfig.setLogLevel(AdjustConfig.LogLevelDebug);     // enable more logging
adjustConfig.setLogLevel(AdjustConfig.LogLevelInfo);      // the default
adjustConfig.setLogLevel(AdjustConfig.LogLevelWarn);      // disable info logging
adjustConfig.setLogLevel(AdjustConfig.LogLevelError);     // disable warnings as well
adjustConfig.setLogLevel(AdjustConfig.LogLevelAssert);    // disable errors as well
adjustConfig.setLogLevel(AdjustConfig.LogLevelSuppress);  // disable all logging

Adjust project settings

Once the Adjust SDK has been added to your app, certain tweeks are being performed so that the Adjust SDK can work properly. Everything that is being done in this process is written in the plugin.xml file of the Adjust SDK plugin. Below you can find a description of every additional thing that the Adjust SDK performs after you've added it to your app.

Android permissions

The Adjust SDK adds three permissions to your Android manifest file: INTERNET, ACCESS_WIFI_STATE and ACCESS_NETWORK_STATE. You can find this setting in the plugin.xml file of the Adjust SDK plugin:

<config-file target="AndroidManifest.xml" parent="/manifest">
    <uses-permission android:name="android.permission.INTERNET" />
    <uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>
</config-file>

INTERNET permission is the permission that our SDK might need at any point in time. ACCESS_WIFI_STATE is the permission which the Adjust SDK needs in case your app is not targetting the Google Play Store and doesn't use Google Play Services. If you are targetting the Google Play Store and you are using Google Play Services, the Adjust SDK doesn't need this permission and, if you don't need it anywhere else in your app, you can remove it. ACCESS_NETWORK_STATE is needed for reading MMC and MNC parameters.

Google Play Services

Since the August 1, 2014, apps in the Google Play Store must use the Google Advertising ID to uniquely identify each device. To allow the Adjust SDK to use the Google Advertising ID, you must integrate Google Play Services.

The Adjust SDK adds Google Play Services by default to your app. This is done with this line in the plugin.xml file:

<framework src="com.google.android.gms:play-services-analytics:+" />

If you are using other Cordova plugins, they might also be importing Google Play Services by default into your app. If this is the case, Google Play Services from our SDK and other plugins can conflict and cause build time errors. Google Play Services does not have to be present in your app as part of our SDK exclusively. As long as you have the analytics part of the Google Play Services library integrated in your app, our SDK will be able to read all the necessary information. In case you choose to add Google Play Services into your app as part of another Cordova plugin, you can simply remove the above line from the plugin.xml file of our SDK.

To check whether the analytics part of the Google Play Services library has been successfully added to your app so that the Adjust SDK can read it properly, you should start your app by configuring the SDK to run in sandbox mode and set the log level to verbose. After that, track a session or some events in your app and observe the list of parameters in the verbose logs which are being read once the session or event has been tracked. If you see a parameter called gps_adid in there, you have successfully added the analytics part of the Google Play Services library to your app and our SDK is reading the necessary information from it.

Proguard settings

If you are using Proguard, add these lines to your Proguard file:

-keep public class com.adjust.sdk.** { *; }
-keep class com.google.android.gms.common.ConnectionResult {
    int SUCCESS;
}
-keep class com.google.android.gms.ads.identifier.AdvertisingIdClient {
    com.google.android.gms.ads.identifier.AdvertisingIdClient$Info getAdvertisingIdInfo(android.content.Context);
}
-keep class com.google.android.gms.ads.identifier.AdvertisingIdClient$Info {
    java.lang.String getId();
    boolean isLimitAdTrackingEnabled();
}
-keep public class com.android.installreferrer.** { *; }

Install referrer

In order to correctly attribute an install of your Android app to its source, Adjust needs information about the install referrer. This can be obtained by using the Google Play Referrer API or by catching the Google Play Store intent with a broadcast receiver.

Important: The Google Play Referrer API is newly introduced by Google with the express purpose of providing a more reliable and secure way of obtaining install referrer information and to aid attribution providers in the fight against click injection. It is strongly advised that you support this in your application. The Google Play Store intent is a less secure way of obtaining install referrer information. It will continue to exist in parallel with the new Google Play Referrer API temporarily, but it is set to be deprecated in future.

Google Play Referrer API

In order to support this in your app, the Adjust SDK adds support for it by default to your app. This is done with this line in the plugin.xml file:

<framework src="com.android.installreferrer:installreferrer:1.0" />

installreferrer library is part of Google Maven repository, so in order to be able to build your app, you need to add Google Maven repository to your app's build.gradle file if you haven't added it already:

allprojects {
    repositories {
        jcenter()
        maven {
            url "https://maven.google.com"
        }
    }
}

Also, make sure that you have paid attention to the Proguard settings chapter and that you have added all the rules mentioned in it, especially the one needed for this feature:

-keep public class com.android.installreferrer.** { *; }

This feature is supported if you are using the Adjust SDK v4.12.0 or above.

Google Play Store intent

The Google Play Store INSTALL_REFERRER intent should be captured with a broadcast receiver. The Adjust install referrer broadcast receiver is added to your app by default. For more information, you can check our native Android SDK README. You can find this setting in the plugin.xml file of the the Adjust SDK plugin:

<config-file target="AndroidManifest.xml" parent="/manifest/application">
    <receiver
        android:name="com.adjust.sdk.AdjustReferrerReceiver"
        android:exported="true">
        <intent-filter>
            <action android:name="com.android.vending.INSTALL_REFERRER" />
        </intent-filter>
    </receiver>
</config-file>

Please bear in mind that, if you are using your own broadcast receiver which handles the INSTALL_REFERRER intent, you don't need the Adjust broadcast receiver to be added to your manifest file. You can remove it, but inside your own receiver add the call to the Adjust broadcast receiver as described in our Android guide.

iOS frameworks

Adjust SDK plugin adds three iOS frameworks to your generated Xcode project:

  • iAd.framework - in case you are running iAd campaigns
  • AdSupport.framework - for reading iOS Advertising Id (IDFA)
  • CoreTelephony.framework - for reading MCC and MNC information
  • AdjustSdk.framework - our native iOS SDK framework

Settings for this can also be found in plugin.xml file of the Adjust SDK plugin:

<framework src="src/ios/AdjustSdk.framework" custom="true" />
<framework src="AdSupport.framework" weak="true" />
<framework src="iAd.framework" weak="true" />
<framework src="CoreTelephony.framework" weak="true" />

If you are not running any iAd campaigns, you can feel free to remove the iAd.framework dependency.

Additional features

You can take advantage of the following features once the Adjust SDK is integrated into your project.

Event tracking

You can use Adjust to track all kinds of events. Let's say you want to track every tap on a button. Simply create a new event token in your dashboard. Let's say that event token is abc123. You can add the following line in your button’s click handler method to track the click:

var adjustEvent = new AdjustEvent("abc123");
Adjust.trackEvent(adjustEvent);

Revenue tracking

If your users can generate revenue by tapping on advertisements or making In-App Purchases, then you can track those revenues with events. Let's say a tap is worth €0.01. You could track the revenue event like this:

var adjustEvent = new AdjustEvent("abc123");
adjustEvent.setRevenue(0.01, "EUR");
Adjust.trackEvent(adjustEvent);

When you set a currency token, Adjust will automatically convert the incoming revenues into a reporting revenue of your choice. Read more about currency conversion here.

Revenue deduplication

You can also add an optional transaction ID to avoid tracking duplicate revenues. The last ten transaction IDs are remembered, and revenue events with duplicate transaction IDs are skipped. This is especially useful for In-App Purchase tracking. You can see an example below.

If you want to track in-app purchases, please make sure to call the trackEvent only if the transaction is finished and an item is purchased. That way you can avoid tracking revenue that is not actually being generated.

var adjustEvent = new AdjustEvent("abc123");
adjustEvent.setRevenue(0.01, "EUR");
adjustEvent.setTransactionId("{YourTransactionId}");
Adjust.trackEvent(adjustEvent);

Note: Transaction ID is the iOS term, unique identifier for successfully finished Android In-App-Purchases is named Order ID.

In-App Purchase verification

If you want to verify your In-App Purchases, you can use Adjust's Purchase Verification product, our server side receipt verification tool. Check out our Cordova purchase SDK and read more about it here.

Callback parameters

You can also register a callback URL for that event in your dashboard and we will send a GET request to that URL whenever the event gets tracked. In that case you can also put some key-value pairs in an object and pass it to the trackEvent method. We will then append these named parameters to your callback URL.

For example, suppose you have registered the URL http://www.adjust.com/callback for your event with event token abc123 and execute the following lines:

var adjustEvent = new AdjustEvent("abc123");
adjustEvent.addCallbackParameter("key", "value");
adjustEvent.addCallbackParameter("foo", "bar");
Adjust.trackEvent(adjustEvent);

In that case we would track the event and send a request to:

http://www.adjust.com/callback?key=value&foo=bar

It should be mentioned that we support a variety of placeholders like {idfa} for iOS or {gps_adid} for Android that can be used as parameter values. In the resulting callback the {idfa} placeholder would be replaced with the ID for Advertisers of the current device for iOS and the {gps_adid} would be replaced with the Google Advertising ID of the current device for Android. Also note that we don't store any of your custom parameters, but only append them to your callbacks. If you haven't registered a callback for an event, these parameters won't even be read.

You can read more about using URL callbacks, including a full list of available values, in our callbacks guide.

Partner parameters

Similarly to the callback parameters mentioned above, you can also add parameters that Adjust will transmit to the network partners of your choice. You can activate these networks in your Adjust dashboard.

This works similarly to the callback parameters mentioned above, but can be added by calling the addPartnerParameter method on your AdjustEvent instance.

var adjustEvent = new AdjustEvent("abc123");
adjustEvent.addPartnerParameter("key", "value");
adjustEvent.addPartnerParameter("foo", "bar");
Adjust.trackEvent(adjustEvent);

You can read more about special partners and networks in our guide to special partners.

Callback identifier

You can also add custom string identifier to each event you want to track. This identifier will later be reported in event success and/or event failure callbacks to enable you to keep track on which event was successfully tracked or not. You can set this identifier by calling the setCallbackId method on your AdjustEvent instance:

var adjustEvent = new AdjustEvent("abc123");
adjustEvent.setCallbackId("Your-Custom-Id");
Adjust.trackEvent(adjustEvent);

Session parameters

Some parameters are saved to be sent in every event and session of the Adjust SDK. Once you have added any of these parameters, you don't need to add them every time, since they will be saved locally. If you add the same parameter twice, there will be no effect.

These session parameters can be called before the Adjust SDK is launched to make sure they are sent even on install. If you need to send them with an install, but can only obtain the needed values after launch, it's possible to delay the first launch of the Adjust SDK to allow this behaviour.

Session callback parameters

The same callback parameters that are registered for events can be also saved to be sent in every event or session of the Adjust SDK.

The session callback parameters have a similar interface of the event callback parameters. Instead of adding the key and its value to an event, it's added through a call to method addSessionCallbackParameter of the Adjust instance:

Adjust.addSessionCallbackParameter("foo", "bar");

The session callback parameters will be merged with the callback parameters added to an event. The callback parameters added to an event have precedence over the session callback parameters. Meaning that, when adding a callback parameter to an event with the same key to one added from the session, the value that prevails is the callback parameter added to the event.

It's possible to remove a specific session callback parameter by passing the desiring key to the method removeSessionCallbackParameter of the Adjust instance:

Adjust.removeSessionCallbackParameter("foo");

If you wish to remove all key and values from the session callback parameters, you can reset it with the method resetSessionCallbackParameters of the Adjust instance:

Adjust.resetSessionCallbackParameters();

Session partner parameters

In the same way that there are session callback parameters that are sent for every event or session of the Adjust SDK, there are also session partner parameters.

These will be transmitted to network partners, for the integrations that have been activated in your Adjust dashboard.

The session partner parameters have a similar interface to the event partner parameters. Instead of adding the key and its value to an event, it's added through a call to method addSessionPartnerParameter of the Adjust instance:

Adjust.addSessionPartnerParameter("foo", "bar");

The session partner parameters will be merged with the partner parameters added to an event. The partner parameters added to an event have precedence over the session partner parameters. Meaning that, when adding a partner parameter to an event with the same key to one added from the session, the value that prevails is the partner parameter added to the event.

It's possible to remove a specific session partner parameter by passing the desiring key to the method removeSessionPartnerParameter of the Adjust instance:

Adjust.removeSessionPartnerParameter("foo");

If you wish to remove all keys and values from the session partner parameters, you can reset it with the method resetSessionPartnerParameters of the Adjust instance:

Adjust.resetSessionPartnerParameters();

Delay start

Delaying the start of the Adjust SDK allows your app some time to obtain session parameters, such as unique identifiers, to be sent on install.

Set the initial delay time in seconds with the setDelayStart field of the AdjustConfig instance:

adjustConfig.setDelayStart(5.5);

In this case this will make the Adjust SDK not send the initial install session and any event created for 5.5 seconds. After this time is expired or if you call sendFirstPackages() of the Adjust instance in the meanwhile, every session parameter will be added to the delayed install session and events and the Adjust SDK will resume as usual.

The maximum delay start time of the Adjust SDK is 10 seconds.

Attribution callback

You can register a listener to be notified of tracker attribution changes. Due to the different sources considered for attribution, this information cannot by provided synchronously. The simplest way is to create a single anonymous listener which is going to be called each time your user's attribution value changes:

With the AdjustConfig instance, before starting the SDK, add the anonymous listener:

var adjustConfig = new AdjustConfig(appToken, environment);

adjustConfig.setAttributionCallbackListener(function(attribution) {
    // Printing all attribution properties.
    console.log("Attribution changed!");
    console.log(attribution.trackerToken);
    console.log(attribution.trackerName);
    console.log(attribution.network);
    console.log(attribution.campaign);
    console.log(attribution.adgroup);
    console.log(attribution.creative);
    console.log(attribution.clickLabel);
    console.log(attribution.adid);
});

Adjust.create(adjustConfig);

Within the listener function you have access to the attribution parameters. Here is a quick summary of its properties:

  • trackerToken the tracker token of the current attribution.
  • trackerName the tracker name of the current attribution.
  • network the network grouping level of the current attribution.
  • campaign the campaign grouping level of the current attribution.
  • adgroup the ad group grouping level of the current attribution.
  • creative the creative grouping level of the current attribution.
  • clickLabel the click label of the current attribution.
  • adid the Adjust device identifier.

Please make sure to consider our applicable attribution data policies.

Session and event callbacks

You can register a callback to be notified of successful and failed tracked events and/or sessions.

Follow the same steps as for attribution callback to implement the following callback function for successfully tracked events:

var adjustConfig = new AdjustConfig(appToken, environment);

adjustConfig.setEventTrackingSucceededCallbackListener(function(eventSuccess) {
    // Printing all event success properties.
    console.log("Event tracking succeeded!");
    console.log(eventSuccess.message);
    console.log(eventSuccess.timestamp);
    console.log(eventSuccess.eventToken);
    console.log(eventSuccess.callbackId);
    console.log(eventSuccess.adid);
    console.log(eventSuccess.jsonResponse);
});

Adjust.create(adjustConfig);

The following callback function for failed tracked events:

var adjustConfig = new AdjustConfig(appToken, environment);

adjustConfig.setEventTrackingFailedCallbackListener(function(eventFailure) {
    // Printing all event failure properties.
    console.log("Event tracking failed!");
    console.log(eventFailure.message);
    console.log(eventFailure.timestamp);
    console.log(eventFailure.eventToken);
    console.log(eventFailure.callbackId);
    console.log(eventFailure.adid);
    console.log(eventFailure.willRetry);
    console.log(eventFailure.jsonResponse);
});

Adjust.create(adjustConfig);

For successfully tracked sessions:

var adjustConfig = new AdjustConfig(appToken, environment);

adjustConfig.setSessionTrackingSucceededCallbackListener(function(sessionSuccess) {
    // Printing all session success properties.
    console.log("Session tracking succeeded!");
    console.log(sessionSuccess.message);
    console.log(sessionSuccess.timestamp);
    console.log(sessionSuccess.adid);
    console.log(sessionSuccess.jsonResponse);
});

Adjust.create(adjustConfig);

And for failed tracked sessions:

var adjustConfig = new AdjustConfig(appToken, environment);

adjustConfig.setSessionTrackingFailedCallbackListener(function(sessionFailure) {
    // Printing all session failure properties.
    console.log("Session tracking failed!");
    console.log(sessionFailure.message);
    console.log(sessionFailure.timestamp);
    console.log(sessionFailure.adid);
    console.log(sessionFailure.willRetry);
    console.log(sessionFailure.jsonResponse);
});

Adjust.create(adjustConfig);

The callback functions will be called after the SDK tries to send a package to the server. Within the callback you have access to a response data object specifically for the callback. Here is a quick summary of the session response data properties:

  • var message the message from the server or the error logged by the SDK.
  • var timestamp timestamp from the server.
  • var adid a unique device identifier provided by Adjust.
  • var jsonResponse the JSON object with the response from the server.

Both event response data objects contain:

  • var eventToken the event token, if the package tracked was an event.
  • var callbackId the custom defined callback ID set on event object.

And both event and session failed objects also contain:

  • var willRetry indicates there will be an attempt to resend the package at a later time.

Disable tracking

You can disable the Adjust SDK from tracking by invoking the method setEnabled of the Adjust instance with the enabled parameter as false. This setting is remembered between sessions, but it can only be activated after the first session.

Adjust.setEnabled(false);

You can verify if the Adjust SDK is currently active with the method isEnabled of the Adjust instance. It is always possible to activate the Adjust SDK by invoking setEnabled with the parameter set to true.

Offline mode

You can put the Adjust SDK in offline mode to suspend transmission to our servers while retaining tracked data to be sent later. When in offline mode, all information is saved in a file, so be careful not to trigger too many events while in offline mode.

You can activate offline mode by calling the method setOfflineMode of the Adjust instance with the parameter true.

Adjust.setOfflineMode(true);

Conversely, you can deactivate offline mode by calling setOfflineMode with false. When the Adjust SDK is put back in online mode, all saved information is send to our servers with the correct time information.

Unlike disabling tracking, this setting is not remembered between sessions. This means that the SDK is in online mode whenever it is started, even if the app was terminated in offline mode.

Event buffering

If your app makes heavy use of event tracking, you might want to delay some HTTP requests in order to send them in one batch every minute. You can enable event buffering with your AdjustConfig instance by calling setEventBufferingEnabled method:

var adjustConfig = new AdjustConfig(appToken, environment);
adjustConfig.setEventBufferingEnabled(true);
Adjust.create(adjustConfig);

GDPR right to be forgotten

In accordance with article 17 of the EU's General Data Protection Regulation (GDPR), you can notify Adjust when a user has exercised their right to be forgotten. Calling the following method will instruct the Adjust SDK to communicate the user's choice to be forgotten to the Adjust backend:

Adjust.gdprForgetMe();

Upon receiving this information, Adjust will erase the user's data and the Adjust SDK will stop tracking the user. No requests from this device will be sent to Adjust in the future.

SDK signature

An account manager must activate the Adjust SDK signature. Contact Adjust support (support@adjust.com) if you are interested in using this feature.

If the SDK signature has already been enabled on your account and you have access to App Secrets in your Adjust Dashboard, please use the method below to integrate the SDK signature into your app.

An App Secret is set by passing all secret parameters (secretId, info1, info2, info3, info4) to setAppSecret method of AdjustConfig instance:

var adjustConfig = new AdjustConfig(appToken, environment);
adjustConfig.setAppSecret(secretId, info1, info2, info3, info4);
Adjust.create(adjustConfig);

Background tracking

The default behaviour of the Adjust SDK is to pause sending HTTP requests while the app is in the background. You can change this in your AdjustConfig instance by calling setSendInBackground method:

var adjustConfig = new AdjustConfig(appToken, environment);
adjustConfig.setSendInBackground(true);
Adjust.create(adjustConfig);

If nothing is set, sending in background is disabled by default.

Device IDs

Certain services (such as Google Analytics) require you to coordinate Device and Client IDs in order to prevent duplicate reporting.

iOS Advertising Identifier

To obtain the IDFA, call the getIdfa method of the Adjust instance. You need to pass a callback to that method in order to obtain the value:

Adjust.getIdfa(function(idfa) {
    // Use idfa value.
});

Google Play Services advertising identifier

If you need to obtain the Google Advertising ID, you can call the getGoogleAdId method of the Adjust instance. You need to pass a callback to that method in order to obtain the value:

Adjust.getGoogleAdId(function(googleAdId) {
    // Use googleAdId value.
});

Inside the callback method you will have access to the Google Advertising ID as the variable googleAdId.

Amazon advertising identifier

If you need to obtain the Amazon advertising ID, you can call the getAmazonAdId method on Adjust instance:

Adjust.getAmazonAdId(function(amazonAdId) {
    // Use amazonAdId value.
});

Inside the callback method you will have access to the Amazon Advertising ID as the variable amazonAdId.

Adjust device identifier

For every device with your app installed on it, the Adjust backend generates a unique Adjust device identifier (adid). In order to obtain this identifier, call the getAdid method of the Adjust instance. You need to pass a callback to that method in order to obtain the value:

Adjust.getAdid(function(adid) {
    // Use adid value.
});

Note: Information about the adid is only available after an app installation has been tracked by the Adjust backend. From that moment on, the Adjust SDK has information about the device adid and you can access it with this method. So, it is not possible to access the adid value before the SDK has been initialised and installation of your app has been successfully tracked.

User attribution

As described in the attribution callback section, this callback is triggered, providing you with information about a new attribution whenever it changes. If you want to access information about a user's current attribution whenever you need it, you can make a call to the getAttribution method of the Adjust instance:

Adjust.getAttribution(function(attribution) {
    // Use attribution object in same way like in attribution callback.
});

Note: Information about current attribution is only available after an app installation has been tracked by the Adjust backend and the attribution callback has been triggered. From that moment on, the Adjust SDK has information about a user's attribution and you can access it with this method. So, it is not possible to access a user's attribution value before the SDK has been initialised and an attribution callback has been triggered.

Push token

To send us the push notification token, add the following call to Adjust whenever you get your token in the app or when it gets updated:

Adjust.setPushToken("YourPushNotificationsToken");

Push tokens are used for Audience Builder and client callbacks, and they are required for the upcoming uninstall tracking feature.

Pre-installed trackers

If you want to use the Adjust SDK to recognize users that found your app pre-installed on their device, follow these steps.

  1. Create a new tracker in your dashboard.

  2. Open your app delegate and add set the default tracker of your AdjustConfig instance:

    var adjustConfig = new AdjustConfig(appToken, environment);
    adjustConfig.setDefaultTracker("{TrackerToken}");
    Adjust.create(adjustConfig);

Replace {TrackerToken} with the tracker token you created in step 2. Please note that the dashboard displays a tracker URL (including http://app.adjust.com/). In your source code, you should specify only the six-character token and not the entire URL.

  1. Build and run your app. You should see a line like the following in the app's log output:

    Default tracker: 'abc123'
    

Deep linking

If you are using the Adjust tracker URL with an option to deep link into your app from the URL, there is the possibility to get info about the deep link URL and its content. Hitting the URL can happen when the user has your app already installed (standard deep linking scenario) or if they don't have the app on their device (deferred deep linking scenario).

Standard deep linking scenario

Standard deep linking scenario is a platform specific feature and in order to support it, you need to add some additional settings to your app. If your user already has the app installed and hits the tracker URL with deep link information in it, your application will be opened and the content of the deep link will be sent to your app so that you can parse it and decide what to do next.

Note for iOS: With the introduction of iOS 9, Apple has changed the way deep linking is handled in the app. Depending on which scenario you want to use for your app (or if you want to use them both to support a wide range of devices), you need to set up your app to handle one or both of the following scenarios.

Deep linking on Android & iOS 8 and earlier

To support deep linking handling in your app for Android and iOS 8 and earlier versions, you can use the Custom URL Scheme plugin which can be found here.

After you successfully integrate this plugin, in the callback method used with the plugin described in this section you will have an access to the content of the URL which opened your app on user's device:

function handleOpenURL(url) {
    setTimeout(function () {
        // Check content of the url object and get information about the URL.
    }, 300);
};

By completing integration of this plugin, you should be able to handle deep linking in Android and iOS 8 and lower.

Deep linking on iOS 9 and later

Starting from iOS 9, Apple has introduced suppressed support for old style deep linking with custom URL schemes like described above in favour of universal links. If you want to support deep linking in your app for iOS 9 and higher, you need to add support for universal links handling.

First thing you need to do is to enable universal links for your app in the Adjust dashboard. Instructions on how to do that can be found in our native iOS SDK README.

After you have enabled universal links handling for your app in your dashboard, you need to add support for it in your app as well. You can achieve this by adding this plugin to your cordova app. Please, read the README of this plugin, because it precisely describes what should be done in order to properly integrate it.

Note: You can disregard any information in the README that states that you need to have a domain and website or you need to upload a file to the root of your domain. Adjust is taking care of this instead of you and you can skip these parts of the README. Also, you don't need to follow the instructions of this plugin for the Android platform, because deep linking in Android is still being handled with Custom URL scheme plugin.

To complete the integration of Cordova Universal Links Plugin after successfully enabling universal links for your app in the Adjust dashboard you must:

Edit your config.xml file

You need to add following entry to your config.xml file:

<widget>
    <universal-links>
        <host name="[hash].adj.st" scheme="https" event="adjustDeepLinking" />
    </universal-links>
</widget>

You should replace the [hash] value with the value you generated on the Adjust dashboard. You can name the event also how ever you like.

Check ul_web_hooks/ios/ content of the plugin

Go to the Cordova Universal Links Plugin install directory in your app and check the ul_web_hooks/ios/ folder content. In there, you should see a generated file with the name [hash].ulink.adjust.com#apple-app-site-association. The content of that file should look like this:

{
  "applinks": {
    "apps": [],
    "details": [
      {
        "appID": "<YOUR_TEAM_ID_FROM_MEMBER_CENTER>.com.adjust.examples",
        "paths": [
          "/ulink/*"
        ]
      }
    ]
  }
}

Integrate plugin to your index.js file

After the deviceready event gets fired, you should subscribe to the event you have defined in your config.xml file, and define the callback method which gets fired once the event is triggered. Because you don't need this plugin to handle deep linking in Android, you can only need to subscribe to it if your app is running on an iOS device.

// ...

var app = {
    initialize: function() {
        this.bindEvents();
    },

    bindEvents: function() {
        document.addEventListener('deviceready', this.onDeviceReady, false);
    },

    onDeviceReady: function() {
        if (device.platform == "iOS") {
            universalLinks.subscribe('adjustDeepLinking', app.didLaunchAppFromLink);
        }
    },

    didLaunchAppFromLink: function(eventData) {
        // Check content of the eventData.url object and get information about the URL.
    }
}
// ...

By completing these steps, you have successfully added support for deep linking for iOS 9 and above as well.

Deferred deep linking scenario

While deferred deep linking is not supported out of the box on Android and iOS, our Adjust SDK makes it possible.

In order to get info about the URL content in a deferred deep linking scenario, you should set a callback method on the AdjustConfig object which will receive one parameter where the content of the URL will be delivered. You should set this method on the config object by calling the method setDeeplinkCallbackListener:

var adjustConfig = new AdjustConfig(appToken, environment);

adjustConfig.setDeferredDeeplinkCallbackListener(function(deeplink) {
    console.log("Deferred deep link URL content: " + deeplink);
});

Adjust.create(adjustConfig);

In deferred deep linking scenario, there is one additional setting which can be set on the AdjustConfig object. Once the Adjust SDK gets the deferred deep link info, we are offering you the possibility to choose whether our SDK should open this URL or not. You can choose to set this option by calling the setShouldLaunchDeeplink method on the config object:

var adjustConfig = new AdjustConfig(appToken, environment);

adjustConfig.setShouldLaunchDeeplink(true);
// or adjustConfig.setShouldLaunchDeeplink(false);

adjustConfig.setDeeplinkCallbackListener(function(deeplink) {
    console.log("Deferred deep link URL content: " + deeplink);
});

Adjust.create(adjustConfig);

If nothing is set, the Adjust SDK will always try to launch the URL by default.

Reattribution via deep links

Adjust enables you to run re-engagement campaigns by using deep links. For more information on this, please check our official docs.

If you are using this feature, in order for your user to be properly reattributed, you need to make one additional call to the Adjust SDK in your app.

Once you have received deep link content information in your app, add a call to appWillOpenUrl method of the Adjust instance. By making this call, the Adjust SDK will try to find if there is any new attribution info inside of the deep link and if any, it will be sent to the Adjust backend. If your user should be reattributed due to a click on the Adjust tracker URL with deep link content in it, you will see the attribution callback in your app being triggered with new attribution info for this user.

In the code examples described above, a call to the appWillOpenUrl method should be done like this:

function handleOpenURL(url) {
    setTimeout(function () {
        // Check content of the url object and get information about the URL.
        Adjust.appWillOpenUrl(url);
    }, 300);
};
// ...

var app = {
    initialize: function() {
        this.bindEvents();
    },

    bindEvents: function() {
        document.addEventListener('deviceready', this.onDeviceReady, false);
    },

    onDeviceReady: function() {
        if (device.platform == "iOS") {
            universalLinks.subscribe('adjustDeepLinking', app.didLaunchAppFromLink);
        }
    },

    didLaunchAppFromLink: function(eventData) {
        // Check content of the eventData.url object and get information about the URL.
        Adjust.appWillOpenUrl(eventData.url);
    }
}
// ...
