title: Cannot resolve symbol 'MediaSessionCompat'
body: <p>I cannot import <code>MediaSessionCompat</code>.
  The import statement for importing the whole <code>android.support.v4.media</code> library does not show up in the Android Studio "IntelliSense" and it cannot resolve the symbol for anything inside it. </p>
  
  <p>Do I have to make some kind of extra configuration to get this import, like in app <code>build.gradle</code>?</p>
