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

In Android Studio, go to your build.gradle (check both project and modules build.gradle files) and search for duplicate dependencies.

Delete those your project does not need.
