OPFPush

Android Arsenal

OPFPush is an open source library which provides an easy way for developers to integrate android push notifications into their apps.

Currently OPFPush supports the following push providers: Google Cloud Messaging, Nokia Notification Push, Amazon Device Messaging and provides possibility to use the system push provider for a specific device.

How To Use

Add dependencies

The main dependencies are the opfmaps module and the OPFUtils library:

compile 'org.onepf:opfpush:0.3.1@aar'
compile 'org.onepf:opfutils:0.1.25'

Then you have to add at least one map provider dependency.

GCM Provider:

compile 'org.onepf:opfpush-gcm:0.3.1@aar'
compile 'com.google.android.gms:play-services:7.8.0'

ADM Push Provider:

compile 'org.onepf:opfpush-adm:0.3.1@aar'
provided 'com.amazon:amazon-device-messaging:1.0.1'

Nokia Push Provider:

compile 'org.onepf:opfpush-nokia:0.3.1@aar'
compile 'com.nokia:push:1.0'

NOTE: If you use ADMProvider or/and NokiaPushProvider you have to add the following repo which hosts amazon-device-messaging.jar and nokia-push.jar:

allprojects {
  repositories {
    ...
    // third-party dependencies
    maven { url 'https://raw.githubusercontent.com/onepf/OPF-mvn-repo/master/' }
  }
}

Update AndroidManfest.xml

Add permissions and receivers required for each used Push Provider:

<!--gcm permissions-->
<uses-permission android:name="${applicationId}.permission.C2D_MESSAGE" />
<permission
   android:name="${applicationId}.permission.C2D_MESSAGE"
   android:protectionLevel="signature" />
   
<!--adm permissions-->
<permission android:name="${applicationId}.permission.RECEIVE_ADM_MESSAGE" />
<uses-permission
   android:name="${applicationId}.permission.RECEIVE_ADM_MESSAGE"
   android:protectionLevel="signature" />
   
<!--nokia-->
<!--The same as for gcm-->
   
<application>

   <!--gcm receiver-->
   <receiver
      android:name="com.google.android.gms.gcm.GcmReceiver"
      android:exported="true"
      android:permission="com.google.android.c2dm.permission.SEND">
      <intent-filter>
         <action android:name="com.google.android.c2dm.intent.REGISTRATION" />
         <action android:name="com.google.android.c2dm.intent.RECEIVE"/>
         <category android:name="${applicationId}"/>
      </intent-filter>
   </receiver>
   
   <!--adm receiver-->
   <receiver
      android:name="org.onepf.opfpush.adm.ADMReceiver"
      android:permission="com.amazon.device.messaging.permission.SEND">

      <intent-filter>
         <action android:name="com.amazon.device.messaging.intent.REGISTRATION" />
         <action android:name="com.amazon.device.messaging.intent.RECEIVE" />

         <category android:name="${applicationId}" />
      </intent-filter>
   </receiver>
   
   <!--nokia receiver-->
   <receiver
      android:name="org.onepf.opfpush.nokia.NokiaNotificationsReceiver"
      android:permission="com.nokia.pushnotifications.permission.SEND">
      
      <intent-filter>
         <action android:name="com.nokia.pushnotifications.intent.RECEIVE" />
         <action android:name="com.nokia.pushnotifications.intent.REGISTRATION" />

         <category android:name="${applicationId}" />
      </intent-filter>
   </receiver>

</application>

Initialization

To setup OPFPush add the following piece of code to your Application.onCreate() method:

public class MyApplication extends Application {

   @Override
   public void onCreate() {
      super.onCreate();
      OPFLog.setEnabled(BuildConfig.DEBUG, true); //Optional. It enables debug logs of the OPFMaps library in the debug build of your apk.

      final Configuration configuration = new Configuration.Builder()
            .addProviders(new GCMProvider(this, GCM_SENDER_ID), new ADMProvider(this), new NokiaNotificationsProvider(this, NOKIA_SENDER_ID)) //Add all providers. The priority of the providers corresponds to the order in which they were added.
            .setSelectSystemPreferred(true) //If you set true, the system push provider will get the highest priority. Default value is false.
            .setEventListener(new PushEventListener(this)) //An implementation of EventListener interface.
            .build();
      
      OPFPush.init(this, configuration); //Init OPFPush using the created Configuration object:
      OPFPush.getHelper().register(); //Start registration.
   }
}

You'll get the registration id into EventListener.onRegistered() callback. After registration you'll start receiving push messages into EventListener.onMessage() callback.

Sample

Take a look at the usage of the OPFPush library in our sample application.

##More Information

Simple interation of Google Cloud Messaging

If you want to start using GCM in your application but don't know how. See the easiest way to implement GCM using OPFPush library.

Using of OPFPushReceiver

You can use BroadcastReceiver instead of EventListener for receiving push events. See the following section

Using of JAR dependencies instead of AARs

You also can use JAR dependencies. See the following section.

Notification payload support

GCM Notification payload support was added to the library. Also we have implemented a similar mechanism for all supported push providers. See the following section

Create Custom Push Provider

To create a custom push provider see the following section.
