[2014-04-09 15:16:51 - Dex Loader] Unable t         


        

Answer 1

I had this problem because I had the google-play-services.jar in my libs folder, while including the play services in build.gradle like this:

dependencies {
  ...
  compile 'com.google.android.gms:play-services:5.0.89'
  ...
}

So I deleted the google-play-services.jar from the libs folder and the app was working fine again
