title: android - using the new android expansion for large applications
body: <p>until recently , for too large apps (50+ MB apps) you had to use your own server to host the large files and add your own logic on the app to download and handle the file from the server.</p>

  it has its limitations and rules , but it's free and i think everyone should consider using it.</p>
  
  <p>my question is : is there any nice tutorial , including sample project , that i can do the minimal changes in order to make it work with my app ? maybe someone has already tested it and would be able to share a sample project?</p>
  
  <p>i've tried to read what they wrote there , and it seems that for every thing i read , there is another link to read from , and in the end i didn't understand the full step-by-step process that i need to go over in order to create a working project.</p>
