title: Random exception android.database.sqlite.SQLiteException: unable to open database file
body: <p>My app uses a uncaught exception handler that sends the stack trace to me when the app crashes. Often I get this report from random users. </p>
  
  <p>I cannot replicate it, the opening of the database always succeeds in my case. This is not a database stored on external SD card, only a database opened with <code>SQLiteOpenHelper(context, "SomeName", null, someVersionCode)</code>.</p>
  
  <p>Do you have any experience with this? What are the possibilities that I can check before opening the database?</p>
  
  <p>Thank you!</p>
