title: Check server for notifications for app and display them if present
body: <p>I am creating an application on Android which has a MySql server. I want a notification if there is any data present in the File (The User has the job to remove it all but after verifying them). So, I need a good background worker which activates after one hour, checks if any data is there, send a notification, close itself and then again activate after one hour. The time <strong>one hour</strong> can be changed. I use a AsyncTask for downloading(Unavoidable). I am good at sending notifications and using AsyncTask.</p>
  
  <p>I am a bit lazy so have not done any experiment before verifying that it will complete my task. </p>
  
  <p>I think it may use the <strong>Service</strong> class. Please provide detailed information. Please give a whole tutorial when telling to use any <em>Github Library</em> cause I am new to Github.</p>
  
  <p>Thank You,</p>
  
  <p>Yours Respectfully,</p>
