Migrate from SDL 2.0.4 to SDL 2.0.7

I use gradle with gradle experimantal plugin "com.android.tools.build:gradle-experimental:0.8.0-rc2"
I use SDL 2.0.4 for android apk building. Apk installs and runs successfully.

I try migrate to SDL 2.0.7 I use new java classess from android-project\src\org\libsdl\app
SDL.java
SDLActivity.java
SDLAudioManager.java
SDLControllerManager.java
and get error

As far I see file src\main\android\SDL_android_main.c is empty now.

My gradle file is

}

// This is just copy out the header file and built lib into distribution
// directory for clint application to use; it is a small overhead of this sample:
// both lib and app are put inside one project space [save maintenance time]
task(distributeLib, type : Copy) {
// trigger build library
dependsOn assemble
into '…/lib/'
from(‘build/outputs/native/release/lib/’) {
into ‘…/lib/’
}
}

What I’m doing wrong?

When I remove all my own class and use only these 4 I get another error
