Problem with Proguard

[jaibatrik]

I was trying to export the example application in the project and was unable to do so. In the aFileChooserExample project, I added the following line in project.properties file -

proguard.config=proguard.cfg

Then I tried to export the project by going to Android Tools > Export signed application package. It gave the following error message -

Conversion to dalvik format failed with error 1

I also observed that the issue happens with optimization options in place. If you don't put optimization options, the APK is exported.

Check if your ProGuard is the latest version. "Dalvik error 1" happens after update of ADT. It's stupid but it always rewrites your ProGuard with some really ancient version that gives this problem.

BTW. I have a similar problem - "Proguard returned with error code 1. See console"

I got the same error. Any hint? I updated to latest ADT and pulled the latest code. Had no problem before using LocalStorageProvider

So stupid of me. Manifest.xml was correctly updated to use API level 19, while in Eclipse's project.properties it was still to 18. Solved.
