Crashed on android device

hi,
I recently updated the urho3d engine code, and run my game demo on iOS and android device.
iOS is ok but on android device It just crash, I think something is wrong.
This is the crash log:

It looks like that crash would happen if you have no C++ shared libraries (.so files) in your android build, so that the list of libraries to load is empty. There should always be at least one .so ( Urho3DPlayer.so in the default build) or else there’s nothing to run.

Yes, it is my fault, I cleaned my project and rebuild it and every thing is ok.
cadaver, thank you very much.
