title: BroadcastReceiver does not get data from notification button
body: <p>I am trying to make notification with remove button, notifications are stored in SQLite DB and after the press, I want to remove "record" by id. Firstly I get a notification, store it to db , store unique id and pass it to a method which creates a notification. It gets fine in the method.</p>
  
  <pre><code>    public static String CUSTOM_ACTION = "com.example.app.Services.REMOVE";
      Intent snoozeIntent = new Intent(this, MyBroadcastReceiver.class);
      snoozeIntent.setAction(CUSTOM_ACTION);
      snoozeIntent.putExtra("NOT_WORKING", String.valueOf(id));
      PendingIntent snoozePendingIntent =
              PendingIntent.getBroadcast(this, 0, snoozeIntent, 0);
  
      Intent intent = new Intent(this, MainActivity.class);
      intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
      PendingIntent pendingIntent = PendingIntent.getActivity(this, 0 /* Request code */, intent,
              PendingIntent.FLAG_ONE_SHOT);
  
      String channelId = getString(R.string.default_notification_channel_id);
      NotificationCompat.Builder notificationBuilder =
              new NotificationCompat.Builder(this, channelId)
              .setDefaults(Notification.DEFAULT_ALL)
              .setSmallIcon(R.drawable.ic_stat_bell)
              .setContentTitle("Loggly")
              .setContentText(messageBody)
              .setAutoCancel(true)
              .setContentIntent(pendingIntent)
              .addAction(R.drawable.ic_delete_forever_black_24dp, "Remove", snoozePendingIntent);
  </code></pre>
  
  <p>then I have a broadcast receiver for handling data from notification. Here is how it looks in my manifest file. </p>
  
  <pre><code>    &lt;receiver android:name=".MyBroadcastReceiver"  android:exported="false"&gt;
          &lt;intent-filter&gt;
              &lt;action android:name="com.example.app.Services.REMOVE"/&gt;
              &lt;category android:name="android.intent.category.DEFAULT" /&gt;
          &lt;/intent-filter&gt;
      &lt;/receiver&gt;
  </code></pre>
  
  <p>And here is the broadcast receiver the value which I got from extras is always null ... I have been trying to find a solution, but with no result.</p>
  
  <pre><code>public class MyBroadcastReceiver extends BroadcastReceiver {
      @Override
      public void onReceive(Context context, Intent intent) {
          Bundle extras = intent.getExtras();
          String id;
  
          if (extras != null) {
              id = extras.getString("NOT_WORKING");
              String ns = Context.NOTIFICATION_SERVICE;
              NotificationManager notificationManager = (NotificationManager) context.getSystemService(ns);
              if (notificationManager != null) {
                  notificationManager.cancel(0);
              }
  
              Intent inten = new Intent(context, RemoveService.class);
              inten.putExtra("NOT_WORKING", id);
              context.startService(inten);
          }
      }
  }
  </code></pre>
  
  <p>Finally, I am starting intent service, which should delete the "record" from the database, but when the broadcast receiver does not receive id it can't do anything.</p>
