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

Question

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

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 from subversion.

Answer 1

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.
