Multiple dex files define Landroid/support/v4/accessibilityservice/AccessibilityServiceInfoCompat

Question

If I run gradle assembleDebug from the command line, I am suddenly getting this error:

UNEXPECTED TOP-LEVEL EXCEPTION:
com.android.dx.util.DexEx         


        

Answer 1

I solved similar error by adding following piece of code to my build.gradle file inside the android block.

android {
    dexOptions {
        preDexLibraries = false
    }
}
