Error migrating Libgdx project from Eclipse to Android Studio

I'm trying to migrate my existing game (written in libgdx) from Eclipse to Android Studio.
After migrating my desktop project work properly, but I have problem with Android project. In android I'm using Admob ads.

I get the following error message:

}

pkgTask.jniFolders.add(new File(projectDir, 'libs'))

}


}
}


I have tried to change android support to other version , but I get same error.

Any help would be appreciated.

Thanks

Answer

Finally I find solution

I created blank new libGDX project using libGDX project setup with same package as my previous setup, and I copy all of my classes from old project to this new one. After all done I get working version of my code.

I didn't notice any differences in buld.gradle filed as comments and @piotrek1543 answers.

I don't know what was problem exactly, but my project now work.

I hope this will help anyone in future!
