Answer 1

You don't need the buffer but you could use the ANativeWindow class if you pass in a Surface from java.

void Java_com_justinbuser_nativecore_NativeMethods_setSurface(JNIEnv * env, jobject this, jobject surface){
        ANativeWindow nativeWindow = ANativeWindow_fromSurface(env, surface);
    int width =  ANativeWindow_getWidth(renderEngine->nativeWindow);
    int height = ANativeWindow_getHeight(renderEngine->nativeWindow);
}
