How can i fix this errors?

Answer 1

The problem is you have multiple imports of the same Library OR Class .

Actually, the error is saying that you have :

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

So, you should check whether you added same jar files more than once. If yes,Remove any one of them from libs folder and clean your project.
