title: Writing/Reading to storage is not working properly on Marshmallow
body: <p>App requests permission from the user upon start and it automatically restarts for that specific OS only. That works properly for the app to detect OBB file. But our game has a downloader system that pulls the files from internet to unlock more levels and it seems like I have to restart the app every time a file has been downloaded for the app to recognize it..any clue?</p>
  
  <p>Yes, indeed the files download (zip files) but the unzipped folders are empty when attempting an unzip.  The folders should have media in them.  For Android OS 6.0 marshmallow.</p>
