Android Studio TransformException : Error:Execution failed for task ':app:transformClassesWithDexForDebug'

Question

I am getting the exception below when I am trying to run the application using Android Studio:

Error:Execution failed for task \':app:transformClasses

Answer 1

In my case I was going back and forth between Expo and Android Studio for react native. Expo wanted one application name in order to build and Android Studio wanted another, once I put it back to the name that android studio wanted it built and deployed fine.

Expo

AppRegistry.registerComponent('main', () => App);

Android Studio

AppRegistry.registerComponent('AwesomeProject', () => App);
