title: Android Studio - disable gradle sync
body: <p>Every time I load Android Studio (1.5), it runs gradle sync, even though nothing has changed since the last run. The funny thing is that a project that sync-ed properly yesterday will fail for random reasons today. Such as "Error:Cause: peer not authenticated" or "Could not reserve enough space for object heap".</p>
  
  <p>Could I disable automatic gradle sync at startup?</p>
