Jo,
Sounds like HandlerThread is almost certainly the way you want to go
here, but you can do a similar thing with a regular thread, using a
public member to control it. You should stop the the thread in onPause
or onStop depending on what its doing.
public class DummyActivity extends Activity {
private StoppableThread worker = new StoppableThread();
public void onStart(Bundle b) {
workers.start();
}
public void onStop() {
worker.runThread = false;
}
}
public class StoppableThread extends Thread() {
public boolean runThread = true;
public void run() {
while (runThread) {
// do some work
}
}
}
Cheers,
Justin
