Unable to execute dex: Multiple dex files define

Well for me, I deleted the file in the libs folder called android support v4.jar and it all worked out. Goodluck :)

I have encountered a similar error today and the reason was that the support library was referenced by two library projects used by my app project but with different versions.

In more details: My app depends on 2 library projects

• FaceBookSDK 3.0 -> which is referencing android-support-v4
• ActionBarSherlock -> which is referencing android-support-v4 but with a modified version to support maps.

To solve the problem I had to make FaceBookSDK library depend on ABS library instead of the support library directly.

This is a build path issue.

• Make sure your bin folder is not included in your build path.

• Right click on your project -> go to properties -> Build Path.

• Make sure that Honeycomb library is in your libs/ folder and not in your source folder.

• Include the libraries in libs/ individually in the build path.

  BTW, you may want to bring in the android-support-v4 library to get Ice Cream Sandwich support instead of the Honeycomb support library.
