How to close a background thread in a service when the service get destroyed

Question

I want to close a background thread in my service in the onDestroy method, because if I stop my service the background thread is still running. Because thread.stop() is deprecated, I don't really know how to do it.

@Override
public int onStartCommand(Intent intent, int flags, int startId)
{
    runAsForeground();

    Runnable service = new Runnable() {
        @Override
        public void run() {


            connect(client,options);

        }
    };

    backgroundThread = new Thread(service);
    backgroundThread.start();
    Log.i(TAG, "onStartCommand methode called");

    return Service.START_NOT_STICKY;
}

Thread life cycle is not the same as Android Context Component life cycle. Stopping the service is not enough to stop the thread which service created. Thread.interrupt() is a option. - You should catch InterruptedException though. If it is not enough, you can check if service is not stopped inside your connect() method.
