title: Android notification .addAction deprecated in api 23
body: <p>What is the proper way to add an action to the notification in <code>API 23</code> since <code>addAction(int icon, CharSequence title, PendingIntent intent)</code> is deprecated ? Couldn't find any example, thank you.</p>
  
  <p>My old action: <code>.addAction(R.drawable.ic_prev, "Previous", prevPendingIntent)</code></p>
