multiple dex files define landroid/support/annotation/AnimRes

Question

The moment I added the android support annotations to my dependencies

compile \'com.android.support:support-annotations:20.0.0\'

I got this erro

Answer 1

Clean project works as a temporary fix, but the issue will reappear on next compilation error.

To fix more reliably, I had to update the dependency to android support-v4 to com.android.support:support-v4:22.2.0.
