Integrate Mapbox offline map sdk in android project

Hi We want to integrate mapbox offline map sdk in our app. What we want is our user will work without sim card and there will be no internet access while they are using app. So we want to pre load map for specific area and allow them to see their current locations on map. and on tap of button that location should be stored on sqllite database. Please note that to get awarded we need sample debug apk of implementation.
