title: Is it possible to block Shared Preferences to avoid being deleted?
body: <p>By default Shared Preferences on Android are being able to be deleted by phone setup. Is it possible to block this ?. Basically i would like to store a Shared Preference as defined on Android documentation but not to allow to delete them by any reason. Ie Phone Setup, App update nor App uninstall. If this is not possible, which storage mechanism would you suggest to do this. I need to store is primitive data mostly.</p>
  
  <p>I am making an application where I need to collect certain data from user and ensure he will have just one opportunity to provide it, otherwise she would be cheating. I agree, best option is to store the data provided on my server but that approach would not work if user turn off internet. I understand both requirements might be very difficult to meet.</p>
