How to fix “Conversion to Dalvik format failed with error 1” when you make Export Unsigned Application Package in Eclipse

Published by Igor Khrupin on

Today I’ve got the “Conversion to Dalvik format failed with error 1” error when make “Android Tools–>Export Unsigned Application Package”

I have ADT 23.0.2

The problem was in the Proguard.

To fix it you can disable Proguard in “project.properties” (Note that it is bad idea) or update Proguard.

The Proguard updating is much better solution for it.

To update it you need download the latest Proguard from here:

http://sourceforge.net/projects/proguard/files/latest/download?source=files

After that copy the “lib” and “bin” dirs from the zip to your sdk/tools/proguard/ to replace the default.

This solution helps me.

Let me know if you have better solution.
