title: Unity Facebook SDK v 7.7 and Google Play Services
body: <p>B.S: I am specifically talking about facebook-unity-sdk-7.7.0 not v 7.3.0
  I am using <code>facebook-unity-sdk-7.7.0</code> and <code>GooglePlayGamesPlugin-0.9.32</code> in my project. It does not let me build for android and fails with error <code>Unable to convert classes into dex format. See the Console for details.</code>. In Facebook SDK 7.3.0 it works by deleting android support v4, but in 7.7 the same thing does not work. </p>
