title: Can't compile MediaRouteButton into project
body: <p>I'm doing in Movie project with CastButton, I completed a sample and this worked perfect. But when I'm doing in true project I have a problem.
  I imported compile into my grande file, but when I create MediaRouteButton I have I got error, I tried many ways but I can't fix it, so I now I really need a help:
  This is: compile file:</p>
  
  <pre><code>compile 'com.android.support:appcompat-v7:25.0.0'
      compile 'com.android.support:mediarouter-v7:25.0.0'
      compile 'com.googlecode.android-query:android-query:0.25.9'
      compile 'com.google.android.gms:play-services-cast-framework:10.2.0'
  </code></pre>
  
  <p>this is logcat:</p>
  
  <pre><code>Caused by: java.lang.NoClassDefFoundError: Failed resolution of: Landroid/support/v7/app/MediaRouteButton;
