Answer 1

an asynchronos task can only execute one time... you are trying to employ it in a while loop... meaning you are trying to use it repeatedly... you need to re-initialize start for each iteration of the while loop...

 while (ispressed){
      start = new YourAsyncTask();
      start.execute(params);
 }

Answer 2

bLeft.setOnTouchListener(new View.OnTouchListener() {

    @Override
    public boolean onTouch(View arg0, MotionEvent event) {
        // TODO Auto-generated method stub
        MyThread start = new MyThread();
         boolean isReleased = event.getAction() == MotionEvent.ACTION_UP || event.getAction() == MotionEvent.ACTION_CANCEL;
         boolean isPressed = event.getAction() == MotionEvent.ACTION_DOWN;

    while (isPressed) {

            start.execute(ip, "left");

            break;
    }
        return false;
    }
});

First of all, isReleased wont be used so get rid of that variable this makes things more complicated.

Seconds thing make sure it ends up in the while loop for example:

`Log.d("debugText", "I am in the while")'

and also log the press state. This will make things more clear while debugging.

Also take a look into the following documentation of Android about painless Threading. Make sure you are using the right stuff.

After debugging you probably will understand why it is not executing. If not, more information is needed.
