6. build gradle Project Level buildscript { repositories { jcenter() mavenLocal() maven { url 'https://maven.google.com' } } dependencies { classpath 'com.google.gms:google-services:3.1.0' } Module: App level dependencies { //Firebase compile 'com.google.firebase:firebase-config:11.2.0' compile 'com.google.firebase:firebase-messaging:11.2.0' } apply plugin: 'com.google.gms.google-services’
7. AndroidManifest.xml <service android:name=".MyFirebaseMessagingService" android:exported="false"> <intent-filter> <action android:name="com.google.firebase.MESSAGING_EVENT" /> </intent-filter> </service> <service android:name=".MyFirebaseInstanceIdService" android:exported="false"> <intent-filter> <action android:name="com.google.firebase.INSTANCE_ID_EVENT" /> </intent-filter> </service>
8. FirebaseInstanceIdService class public class MyFirebaseInstanceIdService extends FirebaseInstanceIdService { @Override public void onTokenRefresh() { String token = FirebaseInstanceId.getInstance().getToken(); Log.d("Token", "Refreshed token: " + token); } }
9. FirebaseMessagingService class public class MyFirebaseMessagingService extends FirebaseMessagingService { @Override public void onMessageReceived(RemoteMessage remoteMessage) { super.onMessageReceived(remoteMessage); //Create Notification Intent intent = new Intent(this, MainActivity.class); intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP); PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, intent, PendingIntent.FLAG_ONE_SHOT); NotificationCompat.Builder notificationBuilder =(NotificationCompat.Builder) new NotificationCompat.Builder(this) .setSmallIcon(R.drawable.images) .setContentTitle("Message") .setContentText(remoteMessage.getNotification().getBody()) .setAutoCancel(true) .setContentIntent(pendingIntent); NotificationManager notificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE); notificationManager.notify(0, notificationBuilder.build()); } }

11. Default Remote Config Parameters: remote_config_param.xml <defaultsMap> <entry> <key>welcome_text</key> <value>Welcome to Firebase RemoteConfig</value> </entry> <entry> <key>welcome_text_color</key> <value>#FFDF1507</value> </entry> <entry> <key>bg_color</key> <value>#000000</value> </entry> </defaultsMap>
12. Firebase Remote Config Instance Variables //Loading the Config Parameters or instance variables firebaseRemoteConfig = FirebaseRemoteConfig.getInstance(); firebaseRemoteConfig.setDefaults(R.xml.remote_config_params); firebaseRemoteConfig.setConfigSettings( new FirebaseRemoteConfigSettings.Builder() .setDeveloperModeEnabled(true) .build() );
13. Apply Remote Config from Firebase: MainActivity.java private void applyConfig() { //Get the widget from XML layout ConstraintLayout layout = (ConstraintLayout) findViewById(R.id.layout); TextView textview = (TextView) findViewById(R.id.textView); //Get the values form Firebase remote configuration String welcomeText = firebaseRemoteConfig.getString("welcome_text"); String welcomeTextColor = firebaseRemoteConfig.getString("welcome_text_color"); String layoutColor = firebaseRemoteConfig.getString("bg_color"); // Set the properties from firebase remote configuration // If any value not set in firebase remote configuration then it gets from default set layout.setBackgroundColor(Color.parseColor(layoutColor)); textview.setText(welcomeText); textview.setTextColor(Color.parseColor(welcomeTextColor)); }
