Answer 1

Hi i think you have two copies of the jar files even i had the same issue i had two copies ie; one copy in the libs folder and another in the drawable folder now delete the extra copy in the drawable folder and clean build the project and it'll work...

Answer 2

I updated eclipse (Help->Check for updates) today (31st january,2013) and now I don't see the error. Before it I had error "Unable to execute dex: Multiple dex files define". Hope this helps.

Or

Try the Below 1

here is a file in bin/dexedLibs The same file exists in libs

Delete it in libs and it should work.

For me it was the android-support-v4.jar.

Hope this helps

This occurs when you have multiple copies of the same class in your build path, or elsewhere in your setup.

For me, this occurred when I had added android-support-v4.jar to my libs/ folder, and somehow eclipse added a second copy to bin/classes/android-support-v4.jar.

Deleting the extra copy in bin/classes solved the problem - unsure why Eclipse made a copy there.

You can test for this with

grep -r YourOffendingClassName YourApp | grep jar
