FireBase Cloud Messaging Not Working <p>I am trying to use FireBase Cloud Messaging. I am receiving a token but its not getting any notifications from console. Here is my Manifest:</p> <pre><code> &lt;?xml version="1.0" encoding="utf-8"?&gt; &lt;manifest xmlns:android="http://schemas.android.com/apk/res/android" package="careerage.jobseeker.app" android:hardwareAccelerated="true" android:versionCode="1" android:versionName="0.0.1"&gt; &lt;uses-sdk android:minSdkVersion="16" android:targetSdkVersion="23" /&gt; &lt;supports-screens android:anyDensity="true" android:largeScreens="true" android:normalScreens="true" android:resizeable="true" android:smallScreens="true" android:xlargeScreens="true" /&gt; &lt;uses-permission android:name="android.permission.INTERNET" /&gt; &lt;uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" /&gt; &lt;android:uses-permission android:name="android.permission.READ_PHONE_STATE" /&gt; &lt;android:uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" /&gt; &lt;application android:hardwareAccelerated="true" android:icon="@drawable/icon" android:label="@string/app_name" android:supportsRtl="true"&gt; &lt;activity android:name=".MainActivity" android:configChanges="orientation|keyboardHidden|keyboard|screenSize|locale" android:label="@string/activity_name" android:launchMode="singleTop" android:theme="@android:style/Theme.DeviceDefault.NoActionBar" android:windowSoftInputMode="adjustResize"&gt; &lt;intent-filter android:label="@string/launcher_name"&gt; &lt;action android:name="android.intent.action.MAIN" /&gt; &lt;category android:name="android.intent.category.LAUNCHER" /&gt; &lt;/intent-filter&gt; &lt;/activity&gt; &lt;service android:name=".TokenService"&gt; &lt;intent-filter&gt; &lt;action android:name="com.google.firebase.INSTANCE_ID_EVENT"/&gt; &lt;/intent-filter&gt; &lt;/service&gt; &lt;service android:name=".NotificationService"&gt; &lt;intent-filter&gt; &lt;action android:name="com.google.firebase.MESSAGING_EVENT"/&gt; &lt;/intent-filter&gt; &lt;/service&gt; &lt;/application&gt; </code></pre> <p></p> <p>And My Code is almost the same as from the sample:</p> <pre><code>public class NotificationService extends FirebaseMessagingService { private void sendNotification(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.drawable.icon) .setContentTitle("Notified") .setContentText(messagebody) .setAutoCancel(true) .setSound(defaultSoundUri) .setContentIntent(pendingIntent); NotificationManager notificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE); notificationManager.notify(0 , notificationBuilder.build()); } private void sendSnackbar(String messagebody) { Toast.makeText(this,"Notified",Toast.LENGTH_LONG).show(); } @Override public void onMessageReceived(RemoteMessage remoteMessage) { Toast.makeText(this,"Message Received",Toast.LENGTH_LONG).show(); Log.d("Notification Received",remoteMessage.getNotification().getBody()); sendNotification(remoteMessage.getNotification().getBody()); sendSnackbar(remoteMessage.getNotification().getBody()); } } </code></pre> <p>I checked the Question here <a href="http://stackoverflow.com/questions/37351354/firebase-cloud-messaging-notification-not-received-by-device">Firebase cloud messaging notification not received by device</a> but still it is not working.</p>
