title: Text-To-Speech STOP Issue
body: <p>I have an activity in which there is a continuous updation of display on the screen and also updation of text to speech. The problem here is while the UI is updating, if I press home button then also the text to speech is not stopped. It is running continuously. I have tried to write the <code>stop()</code> and also <code>shutdown()</code> in <code>pause()</code> and also in <code>destroy()</code> but still its not working. Can anyone please let me know how to stop that?</p>
  
  <p>Please help me. </p>
  
  <p>Thanks a lot.</p>
