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

In my case, the problem is not about JDK nor compiler compliance level 1.6 It was about my SDK build-tools that was "18.1.1". I update build-tools to "21.1.2" and the errors gone.
