title: Google Play Expansion File Location
body: <p>We have a large ~600MB expansion file that we get using the Google Play Expansion APK mechanism.  We also have to unzip this file for actual use.  The entire app plus data thus requires about 1.4 GB of storage.</p>
  
  <p>As far as I can tell Google Play insists of downloading the .obb to the "internal" SD and there doesn't appear to be any way to change this.  We have many users with lots of free space on their "external" SD card but limited space on the internal one.  They are screaming about the app taking so much space.  Is there anything we can do about this?</p>
  
  <p>We currently expand the .obb file to:</p>
  
  <p>getExternalStorageDirectory()/Android/data</p>
  
  <p>I suppose we could ask the user where they wanted it and they could choose the true external SD card.  However that would still leave a (largely useless) .obb file on the internal SD card and Google Play says we cannot delete this.</p>
  
  <p>Does anyone have any suggestions on how to handle this correctly?</p>
