Conversion to Dalvik format failed with error 1 with a scary message in the Console view
Has anyone gotten this message before?
Yes. Not since 2009, though.
Why am I getting it?
Because in the source code of your project, or in a JAR, you have another copy of the java.sql.Savepoint interface, other than the one that comes from the Android runtime.
Where should I go look for "hidden libraries" or "internal libraries" that I might not even be aware of?
Your Eclipse classpath. You may wish to edit your question with a screenshot of your "Order & Export" screen from the build path dialog.
Had the same issue.
The following action helped me to get rid of this error message.
1) Go to Project--> properties-->Java Build Path
2) Select Order and Export tab
3) Deselect the Android Private Libraries and Android Dependencies and click ok
After this the application got launched successfully.
