The Reteno Android SDK for Mobile Customer Engagement and Analytics solutions.

Overview

Reteno is a lightweight SDK for Android that helps mobile teams integrate Reteno into their mobile apps. The server-side library makes it easy to call the Reteno API

The SDK supports

Native Android applications written in Java/Kotlin
Android 8.0 or later (minSdk = 26)

Getting started with Reteno SDK for Android

Add mavenCentral repository in your project level build.gradle:

buildscript {
  repositories {
    mavenCentral()
  }
  ...
}

Add reteno and firebase dependencies in application level build.gradle:

dependencies {
  implementation 'com.reteno:fcm:(latest_version_here)'
  ...
  implementation "com.google.firebase:firebase-messaging:23.1.0"
  implementation "com.google.firebase:firebase-messaging-ktx:23.1.0"
}

Library	Description
com.reteno:fcm	FCM enables push notifications through SDK and all core functionality
firebase:firebase-messaging	Firebase cloud messaging
firebase:firebase-messaging-ktx	Firebase cloud messaging Kotlin extensions

Reteno Android SDK is released under the MIT license. See LICENSE for details.

Setting up SDK

Follow our setup guide to integrate the Reteno SDK with your app.

Step1: Enable androidx in your gradle.properties file

android.useAndroidX=true
android.enableJetifier=true

Step2: Determine Compiler for Java Code

Add com.reteno:fcm and firebase dependencies in build.gradle

Note:

Java 1.8 compiler is required. In app level build.gradle:

android {
    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_8
        targetCompatibility JavaVersion.VERSION_1_8
    }
}

Step3: Declare a notification permission in your manifest.

<manifest ...>
    <uses-permission android:name="android.permission.POST_NOTIFICATIONS"/>
    <application ...>
        ...
    </application>
</manifest>

Step4: Edit your custom Application class and provider API Access-Key at SDK initialization.

Note:

To set up SDK you need an SDK_ACCESS_KEY, visit Managing Mobile SDK Access Keys to get it.

Below is sample code you can add to your application class which gets you started with RetenoSDK. You may need to create a new class that extends the Application on this step. Don't forget to edit your manifest file to use the custom Application class. Also make sure to provide the access-key in the constructor. You may store Reteno access key the way you wish based on your preferences:

package [com.YOUR_PACKAGE];

import android.app.Application
import com.reteno.core.Reteno
import com.reteno.core.RetenoApplication
import com.reteno.core.RetenoImpl

class CustomApplication: Application(), RetenoApplication {

    private lateinit var retenoInstance: Reteno

    override fun onCreate() {
        super.onCreate()
        retenoInstance = RetenoImpl(this, "your_access_key_here")
    }

    override fun getRetenoInstance(): Reteno {
        return retenoInstance
    }
}

Manifest.xml

<application
        android:name=".CustomApplication"
        ...
        >
...
</application>

Step5: Use SDK via `Reteno` interface.

Do not use RetenoImpl directly, access Reteno SDK across your application via your app instance. E.g. in Activity:

val reteno = (application as CustomApplication).getRetenoInstance()

Step6: Handle Runtime Permissions.

Since Android 13 was released you have to make sure you are handling Notification runtime permissions

When user accepts permission, you have to call updatePushPermissionStatus() function from Reteno interface to notify the Reteno SDK that user has granted the permission.

val requestPermissionLauncher = registerForActivityResult(RequestPermission()) { isGranted: Boolean ->
        if (isGranted) {
            (getApplicationContext() as RetenoApplication).getRetenoInstance().updatePushPermissionStatus()
            Toast.makeText(this, "Permission granted", Toast.LENGTH_SHORT).show()
        } else {                    
            Toast.makeText(this, "Permission not granted", Toast.LENGTH_SHORT).show()
        }
    }
    
private fun checkPermissions() {
    if (ContextCompat.checkSelfPermission(this, permission.POST_NOTIFICATIONS) == PackageManager.PERMISSION_GRANTED) {
        return
    } else if (shouldShowRequestPermissionRationale(permission.POST_NOTIFICATIONS)) {
        AlertDialog.Builder(this)
            .setTitle("Notifications blocked")
            .setMessage("Please allow receiving notifications from this app in your device settings")
            .setNegativeButton("Cancel", null)
            .setPositiveButton("Go to Settings") { dialog, which ->
                    val intent = Intent(Settings.ACTION_APPLICATION_DETAILS_SETTINGS)
                    intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK)
                    val uri = Uri.fromParts("package", getPackageName(), null)
                    intent.data = uri
                    startActivity(intent)
                }.show()
    } else {
        requestPermissionLauncher.launch(permission.POST_NOTIFICATIONS)
    }
}

Step7: Set up your Firebase application for Firebase Cloud Messaging:

Follow this manual to set up Reteno admin panel with your Firebase key.

Please check optional items below.

Now you are ready to run your app and send a marketing push notification to your application.

Run your app on a physical Android device to make sure it builds correctly.

Optional. If you use own FCM pushes along with Reteno

If you use your custom FCM service extended from FirebaseMessagingService don't extend it directly. Extend RetenoFirebaseMessagingService instead and call super methods for onCreate, onNewToken, onMessageReceived. E.g.:

class CustomFcmService: RetenoFirebaseMessagingService() {

    override fun onCreate() {
        super.onCreate()
        // Your code here
    }

    override fun onNewToken(token: String) {
        super.onNewToken(token)
        // Your code here
    }

    override fun onMessageReceived(message: RemoteMessage) {
        super.onMessageReceived(message)
        // Your code here
    }
}

Optional. You may add your default icon and color for all Reteno notifications via AndroidManifest.xml

<meta-data
            android:name="@string/notification_icon"
            android:resource="@drawable/ic_notification" />

<meta-data
            android:name="@string/notification_icon_color"
            android:resource="@color/red_dark" />

Optional. Additionally, you can further configure the handling of Deeplinks, Custom Data, and/or Notification Events (Push Received, Notification Clicked). To learn more, please visit the Android Push Handling page.
