title: Shared Preferences reset data when app crashed. Please guide
body: <p>My app got crashed and all the data in <strong>shared preference</strong> got cleared.
  I am saving some flags and maintaining user session in shared preference.
  One of the flag is <strong>IsFirstLaunch</strong>, which tells me whether app is launching for first time or not, if returns true then I am downloading some data from server and storing in <strong>SQLite database</strong>.</p>
  
  <p>Please guide, thanks in advance.</p>
