You can use the Handler constructor that takes a Looper so that its work gets scheduled the thread represented by that Looper. For example, you could create a Handler against the main thread's looper from any other thread like this: new Handler(Looper.getMainLooper()) Now that handler will schedule work on the main thread.

[android-developers] Re: Can't create handler inside thread that has not called Looper.prepare()
Hi Rashmi,
You have to create your Handler in separate thread.
Then you can run that thread in your onCreate() of your Service2, like new
LooperThread();
public Handler mHandler; // Your handler
class LooperThread extends Thread {
public void run() {
Looper.prepare();
mHandler = new Handler() {
public void handleMessage(Message msg) {
// process incoming messages here
}
};
Looper.loop();
}
}
For more info you can look here

Regards,
Yuvi

[android-developers] Re: Can't create handler inside thread that has not called Looper.prepare()
It sounds like you are trying to do something that requires UI, in a service, which has no UI. You'll need to launch your Application in order to do whatever it is you are trying to do. Looper.prepare() is already called when you launch your main activity and you usually get this error when you try to do something that requires it, in a thread outside the loopers thread. You should also read up on how services and activities communicate.
