title: Downloading Unity .obb content via Android app
body: <p>I am trying to make a apk with .obb files, alpha on the store, however when trying to download the .obb it doesnt extract correctly or doesnt load all of the content I am not sure, any help would be appreciated.</p>
  
  <p>its an Android structured app, with a assets folder coming from Unity, (which is the .obb file im making).</p>
  
  <p>I have used the Downloader, License and Zip libraries Google recommends.</p>
  
  <p>The two scenarios I am currently stuck at is:</p>
  
  <p><strong>[Scenario 1]</strong></p>
  
  <p>Using Unity to make a .obb file   <a href="https://i.stack.imgur.com/7TL04.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/7TL04.png" alt="enter image description here"></a></p>
  
  <p>The file contents from the .obb Unity generated for me:
  <a href="https://i.stack.imgur.com/2Dj24.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/2Dj24.png" alt="enter image description here"></a></p>
  
  <p>The application downloads the .obb files correctly, but once i try and launch anything Unity related in the app, it searches for files Unity didnt add to the .obb file and breaks.</p>
  
  <p><strong>[Scenario 2]</strong></p>
  
  <p>I just made my own zip file of the assets folder containing alot more content:<a href="https://i.stack.imgur.com/TAXPw.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/TAXPw.png" alt="enter image description here"></a></p>
  
  <p>gave it the correct naming convention </p>
  
  <blockquote>
    <p>main.versionCode.packageName.obb</p>
  </blockquote>
  
  <p>The apk downloads correctly and starts downloading the .obb file, but fails on 99% with no logs.</p>
  
  <p>Has anyone come across this issue? or maybe can point out what I am doing wrong?  </p>
  
  <p>thanks!</p>
