returning correct multiTouch id [SOLVED]

this is how I will post my entire onTouch method here with some variable-changes to makesolved it more understandable. Since I do not know where Im going wrong.with your help! this is for anyone that might run into a similar problem:

    Log.d(TAG, "actionsString: " + actionString);

adding code for how I move the sprite using this:

   angle = Math.atan2(movingPoint.y - initY,
                 movingPoint.x - initX) / (Math.PI / 180);

        //my sprites position
        spritePosition.x += Math.cos(angle * (Math.PI / 180)) //add delta
                * speed;
        spritePosition.y += Math.sin(angle * (Math.PI / 180)) //add delta
                * speed;

if I print spritePosition its value dosnt change when I press both joysticks, even tho you can very obviously see that the characters speed changes. Rly weird.
