UPDATE
Unfortunately, I didn't solve this issue and what I did is create a new project. Fortunately my new project works. One thing I noticed from my newly created project, when I am sending notification messages, some messages didn't arrive to my device. So I think its my Internet connection problem (my idea only).
I am trying to implement basic receiving of Push Notifications using Firebase. I based this tutorial:
https://www.codementor.io/android/tutorial/send-push-notifications-to-android-with-firebase
My Problem is I don't receive any messages at all. I have sent more than 5 messages using the Firebase Console and still nothing happens.
Here is my implementation of FirebaseInstanceIdService:
public class MyFirebaseInstanceIdService extends FirebaseInstanceIdService {
public static final String debugTag = "MyFirebaseIIDService";
@Override
public void onTokenRefresh() {
super.onTokenRefresh();
//Getting registration token
String refreshedToken = FirebaseInstanceId.getInstance().getToken();
//Displaying token in logcat
Log.e(debugTag, "Refreshed token: " + refreshedToken);
}
private void sendRegistrationToServer(String token) {
//You can implement this method to store the token on your server
//Not required for current project
}
}
My FirebaseMessagingService implementation:
public class MyFirebaseMessagingService extends FirebaseMessagingService {
public static final String debugTag = "MyFirebaseApp";
@Override
public void onMessageReceived(RemoteMessage remoteMessage) {
super.onMessageReceived(remoteMessage);
Log.d(debugTag, "Notification Received!");
//Calling method to generate notification
sendNotification(remoteMessage.getNotification().getTitle(),remoteMessage.getNotification().getBody());
}
//This method is only generating push notification
private void sendNotification(String title, String messageBody) {
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);
Uri defaultSoundUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this)
.setSmallIcon(R.mipmap.ic_launcher)
.setContentTitle(title)
.setContentText(messageBody)
.setAutoCancel(true)
.setSound(defaultSoundUri)
.setContentIntent(pendingIntent);
NotificationManager notificationManager =
(NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
notificationManager.notify(0, notificationBuilder.build());
}
}
My Manifest file:
<uses-permission android:name="android.permission.INTERNET" />
<application
android:allowBackup="true"
android:icon="@mipmap/ic_launcher"
android:label="@string/app_name"
android:supportsRtl="true"
android:theme="@style/AppTheme">
<activity android:name=".activities.MainActivity">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<service
android:name=".messagingservice.MyFirebaseMessagingService"
android:enabled="true"
android:exported="true">
<intent-filter>
<action android:name="com.google.firebase.MESSAGING_EVENT" />
</intent-filter>
</service>
<service android:name=".tokenservice.MyFirebaseInstanceIdService">
<intent-filter>
<action android:name="com.google.firebase.INSTANCE_ID_EVENT" />
</intent-filter>
</service>
</application>
What am I doing wrong? Or what am I lacking to implement?
I am really needing some help with this one. Any help will be greatly appreciated. Thank you very much!
