I have a Mapnik.ZIP file that I manually placed into my phone's internal SD in the OSMDroid folder and my mobile application grabs the .PNG images to use them as tiles on my MapView.
Where should I place this .ZIP file in my project and what type of codes should I be looking into to move this ZIP file to the OSMDroid file automatically, under the assumption that this project/application is something that's downloaded right off the Play Store?
Asset Manager? Should I store the ZIP in my Assets folder then copy the file to my SD?
yes ,you can place them in asset folder ,and oncreate method of main activity ,you can copy them to sdcard/osmdroid folder if it is not there already (can check with file size and file name).
