title: Create Custom Big Notifications
body: <p>I wanted to create a Notification including some controls. Since text and controls are small with default notification size (64dp), i wanted have it larger than default size.<br>
  It is possible to create larger notifications, and I think it is possible to have a custom layout, too, but I don't know how.</p>
  
  <p>To be more specific, the following screenshot shows the notification from spotify (image take from <a href="http://androidauthority.com/spotify-android-notifications-controls-233010/" rel="noreferrer">here</a>): <img src="https://i.stack.imgur.com/XEfAQ.jpg" alt="Spotify notification">  </p>
  
  <p>As you can see, the size is bigger than default. Further, it has some kind of ImageButtons without text - if you use <a href="http://developer.android.com/reference/android/app/Notification.Builder.html#addAction%28int,%20java.lang.CharSequence,%20android.app.PendingIntent%29" rel="noreferrer"><em>Notification.Builder.addAction()</em></a>, you may provide an icon but also need to provide a CharSequence as a description - if you leave the description empty, there will still be space reserved for the text and if you pass <em>null</em>, it will crash.</p>
  
  <p>Can anybody tell me how to create a big notification with a custom layout?  </p>
  
  <p>Thanks</p>
