Android Build fail - java.lang.IllegalArgumentException: already added: Lcom/google/api/client/escape/CharEscapers;

Question

I just prepare small update for my android app, but I get this strange bug when I try to build my app (in debug mode). It will be great if someone smarter could look at this

Answer 1

I have the same problem and here is the solution:

Go to "Build" in the top and "Clean Project" and after "Rebuild the project" It helps me! Also you can go to "Files" and Invalidate caches" and restart the Android Studio

Of corse be sure that manifest is ok and no duplicate includes!

Answer 2

Have a maps project in google_play_services/samples. Install jar from libproject to maven repository, add dependency to maps project and found that error. Using provided scope in dependency section solves the issue.
