  <br/>
  <br/>
  The code is the same for both image: <br/></p>
  
  <pre><code>NotificationCompat.InboxStyle inboxStyle = new NotificationCompat.InboxStyle();
  
  NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(mContext);
  
  
  Notification notification = mBuilder.setSmallIcon(smallIcon).setTicker(title) //title
          .setWhen(System.currentTimeMillis())
          .setAutoCancel(true)
          .setContentTitle(title)
          .setStyle(inboxStyle)
          .setContentIntent(resultPendingIntent)
          .setSound(RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION))
          .setLargeIcon(BitmapFactory.decodeResource(mContext.getResources(), icon))
          .setContentText(notifMessage)
          .build();
  
  NotificationManager notificationManager = (NotificationManager) mContext
      .getSystemService(Context.NOTIFICATION_SERVICE);
  notificationManager.notify(mNotificationId, notification);
  </code></pre>
  
  <p>for info, I use build tools 23.0.2 (newest when this question written). here is my app build.gradle:</p>
  
  <pre><code>apply plugin: 'com.android.application'
  
  android {
           compileSdkVersion 23
           buildToolsVersion "23.0.2"
  ...
  </code></pre>
  
  <p>what's up with the difference?
  any help will be appreciated. thanks in advance</p>
