title: Android: How to enable button when service complete its task?
body: <p>I have two buttons <strong>StartButton</strong> and <strong>StopButton</strong> on MainActivity.java . When I press <strong>StartButton</strong> a <strong>Service</strong> is created and StartButton get <strong>disable</strong>. On pressing <strong>StopButton</strong> Service get destroyed and StartButton get <strong>enable</strong>. </p>
  
  <p>What I wanted to do is to <strong>enable</strong> my Start Button as Service completed its task; it <strong>returns any notification or trigger type event or message value</strong> on my MainActivity.java so my Start Button get enable.</p>
  
  <p>Please give me any idea, concept or code to make it easy for me to understand.</p>
