previous article- Android Maps application New Horizon--mapbox The initial integration of application development--the multi-platform map framework for global applications is described Mapbox Android -end integration steps,

And the Android map application of the new Horizon--mapbox application development of the simple feature extraction, if you want to know the recommendations first read the top two OH
