title: Android: Dropbox access token from account credentials
body: <p>For an experiment I'd like to make it as convenient for the users as possible to submit their data. I figured a good way of doing this would be to create a dedicated dropbox account which is hardcoded into the app and allows the user to submit data without any account required for himself.</p>
  
  <p>My question: Is there a way to obtain an access token from the dropbox API with just having username + password at hand (which would be hard coded into the app)?</p>
