My app works fine when it’s unsigned (debugging, etc..), also when exporting without ProGuard.
But when I export it with ProGuard, When a piece of code containing native methods that I import is executing, it crashes.

What can I do? I guess that getting the stack trace, but I have no idea how to do that…

I have tried this: How do I obtain crash-data from my Android application? But no files actually appear where they should (I guess I have done that wrong too :()

The device MUST be saving crash stack traces SOMEWHERE. Where are they?

    The proguard.cfg in your project has a collection of ignore rules for classes that shouldn’t be obfuscated. You can essentially ignore everything and slowly obfuscate code each pass. Native methods, methods called by reflection-indirection shouldn’t be obfuscated.
