If you wanna make a thread...

new Thread(new Runnable() {
       public void run() {
               // do stuff that doesn't touch the UI here
       }
}).start();

it was taken from here.

new Thread(new Runnable() {
       public void run() {
               Looper.prepare();
               // do stuff that can touch the UI here
               Looper.loop();
       }
}).start();
