title: The source attachment does not contain the source for the file SQLiteOpenHelper.class
body: <p>I had a sample app in android version 4.2. I had set Breakpoints for each and every line. At the time of debugging, suddenly the debugging stopped saying that "The source attachment does not contain the source for the file SQLiteOpenHelper.class". </p>
  
  <p>I attached the jar file and still it reports the error. Installed everything currently. But  dont know the cause for this error.</p>
  
  <p>This is my MainActivity.java</p>
