Android Push Notifications

Push Notifications on Android are sent with the help of the FCM service.

How to create a project in Firebase and integrate Firebase Services into your application, you can find in Firebase documentation.

Next, you need to specify the FCM Server key in the push notifications integration settings panel in the application settings section in devtodev service (App → Settings → Push notifications → Push notifications panel)

To get the FCM Server key, go to the Project Settings of your Android project in the Firebase Console and copy the Server key from the Cloud Messaging tab.

Messaging Module Integration

The Messaging module is available as an AAR (recommended) and JAR library. The library is available in the MavenCentral and GitHub repository.

1. If you use Gradle for the applications build, add mavenCentral() into gradle.build file of your application and specify the following relationship in dependencies block:

dependencies {
    implementation ‘androidx.preference:preference-ktx:1.1.1
    implementation 'com.android.installreferrer:installreferrer:2.2'
    implementation 'com.google.android.gms:play-services-base:17.6.0'
    implementation 'com.google.code.gson:gson:2.8.6'
    implementation 'com.google.firebase:firebase-core:19.0.0'
    implementation 'com.google.firebase:firebase-messaging:22.0.0'
    // if you use AAR (recommended) or JAR downloaded from GitHub, please add:
    implementation fileTree(dir: "libs", include: ["*.aar"])
    // or just add the dependency
    implementation 'com.devtodev:android-analytics:2.0.0'
    implementation 'com.devtodev:android-messaging:2.0.0'
}

2. To the app manifest add the following:

<application>
        <service
            android:name="com.devtodev.push.internal.logic.DTDFcmMessagingService"
            android:exported="false">
            <intent-filter>
                <action android:name="com.google.firebase.MESSAGING_EVENT"/>
            </intent-filter>
        </service>

        <receiver
            android:name="com.devtodev.push.internal.logic.PushClickReceiver"
            android:enabled="true"
            android:exported="true">
            <intent-filter>
                <action android:name="com.devtodev.android.push.CLICKED" />
            </intent-filter>
        </receiver>
  </application>

3. To add a user icon to your push notification and change its color, add the following strings to the manifest file code:

<meta-data
 android:name="com.devtodev.push.default_small_icon"
 android:resource="@drawable/ic_icon_name" />

<meta-data
 android:name="com.devtodev.push.default_small_icon_color"
 android:resource="@color/icon_color" />

To add a large user icon to your push notifications, add:

<meta-data
android:name="com.devtodev.push.default_large_icon"
android:resource="@mipmap/ic_large_icon_name"/>

Example:

<application
    <!-- Your tags -->
    <service
        android:name="com.devtodev.push.internal.logic.DTDFcmMessagingService">
        <intent-filter>
            <action android:name="com.google.firebase.MESSAGING_EVENT" />
        </intent-filter>
    </service>

    <receiver
        android:name="com.devtodev.push.internal.logic.PushClickReceiver"
        android:enabled="true"
        android:exported="true">
        <intent-filter>
            <action android:name="com.devtodev.android.push.CLICKED" />
        </intent-filter>
    </receiver>

    <meta-data
        android:name="com.devtodev.push.default_small_icon"
        android:resource="@drawable/ic_baseline" />

    <meta-data
        android:name="com.devtodev.push.default_small_icon_color"
        android:resource="@color/colorPrimary" />

    <meta-data
        android:name="com.devtodev.push.default_large_icon"
        android:resource="@mipmap/baseline_accessibility_black_18"/>
</application>

4. After the DTDAnalytics initializer, add the DTDMessaging initializer.

Example:

val analyticsConfiguration = DTDAnalyticsConfiguration()
analyticsConfiguration.logLevel = DTDLogLevel.Error
DTDAnalytics.initialize("progectKey",analyticsConfiguration,context)
DTDMessaging.initialize(context)

5. Subscribe a DTDPushListener to receive information about the DTDMessaging functioning.

Example:

DTDMessaging.setPushListener(object : DTDPushListener {
      override fun onPushServiceRegistrationSuccessful(deviceId: String) {
          //do something
      }
      override fun onPushServiceRegistrationFailed(error: String) {
          //do something
      }
      override fun onPushNotificationReceived(message: Map<String, String?>?) {
          //do something
      }
      override fun onPushNotificationOpened(pushMessage: DTDPushMessage, actionButton: DTDActionButton?) {
          //do something
      }
})

6. Call the DTDMessaging.startPushService() method to activate the Messaging module.

DTDMessaging.processPushNotification(Context context, RemoteMessage remoteMessage)	Used to pass the push notification to the FirebaseMessagingService if it was implemented by the client but not by the SDK.
DTDMessaging.setPushListener(DTDPushListener pushListener)	(DTDPushListener pushListener) - sets a listener for push notification event trapping.
