title: Android MediaStyle NotificationCompat displays 3 actions maximum
body: <p>I have 2 problems with my NotificationCompat.Builder set up as MediaStyle :</p>
  
  <p>1)  I set up 5 actions and only 3 are displayed in the expanded notification. (The first 3 displayed actions are working fine).</p>
  
  <p>2)  None action is displayed in the compact notification though I set up 1 action.</p>
  
  <p>I'm testing on a Samsung S4 on Lollipop 5.1.1 (Cyanogen) and my app uses support library 23.2.1</p>
  
  <p>Below is my NotificationCompat.Builder :</p>
  
  <pre><code>        notificationBuilder = new NotificationCompat.Builder(act)
              .setPriority(NotificationCompat.PRIORITY_HIGH)
              .setVisibility(NotificationCompat.VISIBILITY_PUBLIC)
              .setCategory(NotificationCompat.CATEGORY_TRANSPORT)
              .setContentTitle(podcastName)
              .setContentText(episodeName)
              .setOngoing(true)
              .setShowWhen(true)
              .setContentIntent(activityMainPI)
              .setSmallIcon(smallIcon)
              .setLargeIcon(largeIcon)
              .setAutoCancel(false)
              .addAction(previousAction)
              .addAction(playAction)
              .addAction(nextAction)
              .addAction(rewindAction)
              .addAction(forwardAction)
              .setStyle(new MediaStyle()
                              .setShowActionsInCompactView(new int[]{1})
              );
  </code></pre>
