Firebase Cloud Message

• To integrate Firebase push notifications, configure strings.xml, add the required permissions to the <manifest> root node of manifest.xml, and add the required component declarations to the <application> node. These declarations have already been configured in the delivered SDK, as shown below.

Configure strings.xml

• Enable Firebase push notifications in strings.xml:

<!--Whether Firebase push notifications are integrated: 1 = integrated, 0 = not integrated (default)-->
    <string name="is_access_firebase">1</string>

Configure manifest.xml

• Add the permission declarations. Add each permission only once in either the SDK or the game; otherwise, an error will occur at runtime:

    <uses-permission android:name="com.google.android.c2dm.permission.RECEIVE" />
    <permission
        android:name="{package name}.permission.C2D_MESSAGE"
        android:protectionLevel="signature" />
    <uses-permission android:name="{package name}.permission.C2D_MESSAGE" />

• Add the related component declaration:

        <service
            android:name="com.gd.fcmpush.GDFirebaseMessagingService"
            android:exported="false" >
            <intent-filter android:priority="-500" >
                <action android:name="com.google.firebase.MESSAGING_EVENT" />
            </intent-filter>
        </service>

---

• If the game also uses Firebase push notifications, register a broadcast receiver with the com.gd.fcm.action action in the manifest, then obtain the RemoteMessage object from the intent parameter of the receiver's onReceive method, as shown below:
• Register the broadcast receiver:

<receiver android:name="{your custom broadcast receiver}">
            <intent-filter>  
                <action android:name="com.gd.fcm.action" />  
            </intent-filter>  
</receiver>

• FcmReceiver class:

public class "{your custom broadcast receiver}" extends BroadcastReceiver{

	@Override
	public void onReceive(Context context, Intent intent) {
		RemoteMessage remoteMessage = (RemoteMessage) intent.getExtras().get("remoteMessage");
		// TODO Handle the game's Firebase push notification logic.
	}
}
