Dex Loader Unable to execute Multiple dex files define

Question

Okay, now i'm really stuck here. I don't know what to do, where to go or ANYTHING!

I have been trying to uninstall, reinstall, both SDK and Eclipse-versions, trying to Google this out, but nu-uh... Nothing!!!

I CAN run my app in emulator, but i cant EXPORT it...

I suspect:

import java.io.FileOutputStream; import java.io.IOException; import java.io.InputStream; import java.io.OutputStream; 

But I don't know what to do... Please help !!! :'(

Answer 1

There 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
