Dx bad class file magic (cafebabe) or version (0033.0000) with ADK14

Question

Since moving to ADK14, I have been unable to build new apks for release on my Windows 7 system.

Building fails with \"conversion to dalvik format failed with error 1

Answer 1

For the benefit of anyone who may have the same problem:

Removing proguard allowed the export of the apk to work. Why Proguard works in Linux but not on Windows remains a mystery, however.

The issue has now been reported on the Android project here: http://code.google.com/p/android/issues/detail?id=21170&can=4&colspec=ID%20Type%20Status%20Owner%20Summary%20Stars
