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 my case the problem was caused by version inconsistency:

Build tools 25
compileSdk 24
targetSdk 24
Support library 24

The solution was simple: Make everything version 25
