@Override
public void onCreate(){
twitterThread = new TwitterThread();
twitterThread.setName("TwitterThread");
twitterThread.start();
mHandler = twitterThread.twitterHandler;
mHandler.setService(this);
}

Message message = Message.obtain();
mHandler.sendMessage(message);
}
class TwitterThread extends Thread {
TwitterHandler twitterHandler;
@Override
public void run() {
Looper.prepare();

}
@Override
public int onStartCommand(Intent intent, int flags, int startId){
Message message = Message.obtain();
twitterThread.twitterHandler.sendMessage(message);
return Service.START_REDELIVER_INTENT;
}
class TwitterThread extends Thread {
TwitterHandler twitterHandler;
@Override
public void run() {
Looper.prepare();
twitterHandler = new TwitterHandler();
Looper.loop();
}
}
class TwitterHandler extends Handler {
@Override
public void handleMessage(Message msg) {
twitterClient.update();
}
}
}```
