Unable to execute dex: Multiple dex files define Lcom/myapp/R$array;

Since updating to

ADT
14 I can no longer build my project. It was building fine prior to updating.

The error:

[2011-10-23 16:23:29 - Dex Loader] Unable to execute dex: Multiple dex files define Lcom/myapp/R$array;
[2011-10-23 16:23:29 - myProj] Conversion to Dalvik format failed: Unable to execute dex: Multiple dex files define Lcom/myapp/R$array;


Similar issues have been reported and I have tried the suggestions there including


  • Restarting
    Eclipse
    .

  • Cleaning the project and rebuild - Disable "Project->Build Automatically" option, then "Clean" and "Build" project, then try to run. reset "Build Automatically" option to On

  • Re-installing the
    Android
    Developer Tools

  • Re-installing Eclipse (updated to the latest version 3.7.1)

  • Created a new project importing from the file system

  • Created a new project from subversion.


Answer

My problem was resolved after cleaning up some directories and files left over from the previous versions of the tools. ADT Rev 14 changes where binaries are stored. I deleted the entire bin directory, restarted Eclipse and cleaned the build and forced a rebuild. That seemed to do the trick initially but the problem came back after the next run.

I finally discovered that my bin directory was included in the project build path. I excluded bin from the build path and repeated the steps above. This resolved my problem.
