FCM : onMessageReceived is not called,notification didn't came even after sending msg to fcm?
<p>i am developing an app where i want to implement FCM push notifications through php.</p>

<p>So i made two java files: 
1.FirebaseInstanceID (Working fine and getting token properly in database)
2.FirebaseMessagingSerivice (Not Called)</p>

<p><strong>My FirebaseMessagingService.java</strong></p>

<pre><code>package com.example.xyz;

import android.app.NotificationManager;
import android.app.PendingIntent;
import android.content.Intent;
import android.support.v4.app.NotificationCompat;
import com.google.firebase.messaging.RemoteMessage;

public class FirebaseMessagingService extends com.google.firebase.messaging.FirebaseMessagingService{

@Override
public void onMessageReceived(RemoteMessage remoteMessage) {

    showNotification(remoteMessage.getData().get("message"));
}

private void showNotification(String message) {

    Intent i = new Intent(this,Dashboard.class);
    i.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);

    PendingIntent pendingIntent = PendingIntent.getActivity(this,0,i,PendingIntent.FLAG_UPDATE_CURRENT);

    NotificationCompat.Builder builder = new NotificationCompat.Builder(this)
            .setAutoCancel(true)
            .setContentTitle("FCM Test")
            .setContentText(message)
            .setSmallIcon(R.drawable.common_google_signin_btn_icon_dark)
            .setContentIntent(pendingIntent);

    NotificationManager manager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);

    manager.notify(0,builder.build());
}
}
</code></pre>

<p><strong>My result when i run my php script to send message to FCM:</strong></p>

<pre><code> {\"multicast_id\":7077449602201888040,\"success\":1,\"failure\":0,\"canonical_ids\":0,\"results\":[{\"message_id\":\"0:1465110073498648%d215149df9fd7ecd\"}]}
</code></pre>

<p>But still i don't get any notification and all the configurations like api key,package name (in fcm console,my project) are checked and they are fine.</p>

<p>When i debug the app by creating breakpoint at onMessageReceived() in FirebaseMessagingService.java, it doesn't go through that and app runs normally when message is pushed through php script to fcm server.</p>

<p><strong>My Dashboard.java</strong></p>

<pre><code>public class Dashboard extends AppCompatActivity {

private Toolbar toolbar;
private DrawerLayout drawer_layout;
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_dashboard);

    toolbar=(Toolbar) findViewById(R.id.app_bar);
    setSupportActionBar(toolbar);
    getSupportActionBar().setDisplayShowHomeEnabled(true);

    drawer_layout=(DrawerLayout) findViewById(R.id.drawer_layout);
    NavigationDrawerFragment drawerfragment= (NavigationDrawerFragment) getSupportFragmentManager().findFragmentById(R.id.fragment_navigation_drawer);
    drawerfragment.setUp(R.id.fragment_navigation_drawer,drawer_layout,toolbar);


    FirebaseMessaging.getInstance().subscribeToTopic("test");
    FirebaseInstanceId.getInstance().getToken();

}
</code></pre>

<p>But My dashboard activity contains a fragment over it.I don't that whether it may be a problem.</p>
