Pointer to the Asset Manager instance for the application. The application uses this to access binary assets bundled inside its own .apk file.
Pointer to the callback function table of the native application. You can set the functions here to your own callbacks. The callbacks pointer itself here should not be changed; it is allocated and managed for you by the framework.
The NativeActivity object handle.
JNI context for the main thread of the app. Note that this field can ONLY be used from the main thread of the process; that is, the thread that calls into the ANativeActivityCallbacks.
Path to this application's external (removable/mountable) data directory.
This is the native instance of the application. It is not used by the framework, but can be set by the application to its own instance state.
Path to this application's internal data directory.
Available starting with Honeycomb: path to the directory containing the application's OBB files (if any). If the app doesn't have any OBB files, this directory may not exist.
The platform's SDK version code.
The global handle on the process's Java VM.
This structure defines the native side of an android.app.NativeActivity. It is created by the framework, and handed to the application's native code as it is being launched.
