title: Android SQLite delete table not actually deleting the rows
body: <p>Hi i am trying to delete all the rows in a table by below query</p>
  
  <pre><code>db.beginTransaction(); // db is a SQLiteDatabase object
  int deleted = db.delete("user", null, null);
  db.endTransaction();
  </code></pre>
  
  <p>I am getting n number of rows deleted in the table. But still rows exist in the table. Anything wrong in my delete call?</p>
