title: HowTo: Provide notification to Android app whenever SQLite table updates
body: <p>I am in process of developing an Android tablet app using sqllite 3.7.4 which would 
  perform following:</p>
  
  <ol>
  <li><p>Fetches information from the UI</p></li>
  <li><p>Performs some logic and store related information to the sqlite database</p></li>
  <li><p>The stored information has to be send immediately OR at schedule
  interval (ex. at 5:00 on xyz date) over the network</p></li>
  </ol>
  
  <p>Currently, we have developed a dispacher mechanism (thread ), which constantly polls the database for new information inserted in the database. The thread fetches the information and send to the network module.</p>
  
  <p>But, I feel this is not the correct approach as 
  Polling every time is a overhead. There can be times when there is nothing to execute
  It is not real time , because we poll after every 5 seconds</p>
  
  <p>So </p>
  
  <p>Is there a way to send a trigger to my network module as soon as information is updated in database?</p>
  
  <p>Or any better way to achieve this task?</p>
  
  <p>Thanks in advance.</p>
