Question

I am struggling with an Android app to handle things new to me. I created a thread, persistent message subscriber, in my app waiting for the messages from server in the background. When I exit my app, the thread is still working. Actually, the thread try to connect again and again when it fails to connect to server. So I want to check my app is down or stil alive, otherwise I want to make my app send some message to the thread to stop before it goes down.

What ways would be there to do that in Android?

Answer 1

You cannot destroy. Android will only stop the thread when required. You cannot stop or destroy it.

Instead try like this: Set some flag in thread, to check when it should run and when it should stop. Like this:

 void run()
{
 while(bool){
   //My code 
 }
 }

Now in onstop of your activity
Change the bool value to false:

@Override
 protected void onStop() {
  // TODO Auto-generated method stub
  super.onStop();
bool=false
   }
