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 to figure out what might been wrong. I was cleaning/rebuild/fix project properties, but with no results. I have no clues what is going on :(. Maybe something similar happen to anyone here? If this can help I use following libraries: adMob(4.1.1), openfeint and libgdx.

here is building log:

[2011-12-08 21:56:42 - JellyBallsFree] Conversion to Dalvik format failed with error 1

Answer 1

You have same jar library included twice. Check your application and all referenced Android libraries and make sure you have all jars included exactly once.

If that does not help, take a look at http://tools.android.com/knownissues. Specifically look at first issue described in Build System section.

Also you can read this post: How to fix the “Conversion to Dalvik format failed with error 1"

Answer 2

I got this error after upgrading to R17.

My cause was different (ie not the *_src issue that occurred in R15). I had two different versions of a library in my "libs" folder. It appears that the Android plugin now automatically adds any jars in "libs" to the "Android Dependencies" section in the Package Explorer. Removing the old jar fixed the problem.

Answer 3

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 4
