Answer 1

Stopping a thread or a process immediately is often a dirty thing. However, it should be fine if your service is stateless.

Declare the service as a separate process in the manifest:

And when you want to stop its execution, just kill that process:

ActivityManager am = (ActivityManager) getSystemService(ACTIVITY_SERVICE);
List runningAppProcesses = am.getRunningAppProcesses();

Iterator iter = runningAppProcesses.iterator();

while(iter.hasNext()){
    RunningAppProcessInfo next = iter.next();

    String pricessName = getPackageName() + ":service";

    if(next.processName.equals(pricessName)){
        Process.killProcess(next.pid);
        break;
    }
}
