Is your project dependent on other modules..if yes then you must have included that module more than once in the project hence the error..Multiple dex files define — therealprashant, Mar 11 '15 at 11:06

Looks like you are using dependencies from two different version of support library, making Landroid/support/v4/accessibilityservice/AccessibilityServiceInfoCompatIcs available in both libraries, which generates conflict on build.

It's better to check your dependency graph. Open Terminal from studio,and cd to your app module and run this command ..\gradlew -q dependencies. It will list all dependencies with parent dependencies, chances are high that you will find your conflicting Support Library there.

In Case of any confusion, update your question with your dependency graph. And beware of your jar files from your libs directory. I fear it may be skipped by dependency graph...
