Unity/Android library project crash

Hi everybody.

I am working with unity/android projects and i'm with some troubles with 'gdbserver'. I have my unity project (module) inside my main project and i'm working with Android Studio. I can load all native files (except the gdbserver) with some code, like:

static { System.loadLibrary("libmain"); etc... }

When i call 'UnityPlayerNativeActivity.java', in my main project, all libraries are loaded but the app crash...

Anybody knows how can i fix this problem?

Thanks a lot,
