01-01 21:01:25.094  11590-11590/com.abc.ads E/AndroidRuntime﹕ FATAL EXCEPTION: main

There are answers for this same issue in SO itself. But all of them are "ecclipse" related. How solve this in Android Studio?

Answer 1

Upgrade to Android Studio 0.4.0 or later, or clean and rebuild your project if you want to stay on 0.3.2. There's a bug in the 0.6 versions of the Gradle plugin ( https://code.google.com/p/android/issues/detail?id=63366 ) that can cause newly-added dependencies to not get linked into your APK unless you clean your project after doing so.
