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:

Answer 1

I was getting this error after adding the facebooksdk.jar to a project that already had dependencies on the android-support-v4.jar. Since the facebooksdk.jar already includes its own android-support-v4.jar there were conflicts. Removing the earlier android-support-v4.jar from the projects Properties / Java Build Path / Libraries resolved the issue for me.
