title: Android SQL Backup
body: <p>Is there any <strong>Android Official</strong> way of doing sql db backup to SD or Phone? there are several  backup helper classes mentioned in the document but all of 'em are pretty useless.</p>
  
  <p>I know that the sql file is a simple db file i can use Java IO class to read and write somewhere. but that is not a wise idea if we have latest version of App which contains several  newly added columns in it. we cannot restore back.</p>
  
  <p>Are there anyway to overcome this issue? Any easy way that so called android engineers provided in the document?</p>
