title: Table has no column named "Column Name" In SQLite with android
body: <p>I am writing an android application and trying to store my data in a db.
  How ever I am getting the error : </p>
  
  <p><strong>"Table Friend_Master has no column named Profile_Pic_Url"</strong></p>
  
  <p>I've gone through all the posts of this kind and tried "uninstalling and re-installing" and "clear data" but didn't work.</p>
  
  <p>Here is my code :</p>
