Multi touch code doesnt work

So I am wroking on game game for android and it requires the use of multi touch. I have read some tutorials about multi touch and tryed to use it in my game. This is my code:

    public boolean onTouch(MotionEvent e) {
    int pointerCount = e.getPointerCount();

    for (int i = 0; i < pointerCount; i++) {
        int x = (int) e.getX(i);
        int y = (int) e.getY(i);
        int action = e.getActionMasked();

        for (int j = 0; j < object.size(); j++) {
            tempObject = object.get(j);
            if (tempObject.getId() == ObjectId.Player) {

                switch (action) {

                case MotionEvent.ACTION_UP:
                    if (moveLeft.contains(x, y)) {
                        tempObject.setMovingLeft(false);

                    }
                    if (moveRight.contains(x, y)) {
                        tempObject.setMovingRight(false);

                    }

                    break;
                case MotionEvent.ACTION_POINTER_UP:
                    if (moveLeft.contains(x, y)) {
                        tempObject.setMovingLeft(false);

                    }
                    if (moveRight.contains(x, y)) {
                        tempObject.setMovingRight(false);

                    }

                    break;

                case MotionEvent.ACTION_DOWN:
                    if (jump.contains(x, y)) {
                        if (tempObject.getVelY() == 0 && tempObject.isJumping() == false) {
                            tempObject.setVelY((float) -11.5);
                            tempObject.setJumping(true);
                        }
                    }
                    if (restart.contains(x, y)) {
                        restart();

                    }

                    break;
                case MotionEvent.ACTION_POINTER_DOWN:
                    if (jump.contains(x, y)) {
                        if (tempObject.getVelY() == 0 && tempObject.isJumping() == false) {
                            tempObject.setVelY((float) -11.5);
                            tempObject.setJumping(true);
                        }
                    }
                    if (restart.contains(x, y)) {
                        restart();

                    }

                    break;

                case MotionEvent.ACTION_MOVE:

                    if (moveLeft.contains(x, y)) {
                        tempObject.setMovingLeft(true);
                        tempObject.setMovingRight(false);

                    }
                    if (moveLeftExit.contains(x, y) && !moveLeft.contains(x, y)) {
                        tempObject.setMovingLeft(false);

                    }
                    if (moveRight.contains(x, y)) {
                        tempObject.setMovingRight(true);
                        tempObject.setMovingLeft(false);

                    }
                    if (moveRightExit.contains(x, y) && !moveRight.contains(x, y)) {
                        tempObject.setMovingRight(false);

                    }
                    break;
                }
            }
        }

    }
    return true;
}

EDIT: I had a mistake mixing the for loops varibels, now it doesnt crash but the touch doesnt work.

EDIT2: I have now noticed that the multi touch works, but it gets trigered when I press in a different place than the Rectangles where it should..

EDIT3: Now the good part is that the multi touch work,as in I can press two buttons and they both react. The bad part is that they react when I touch a different and smaller place. I hope you can understand from this picture:

enter image description here

black - Where it is suppose to trigger the touch event

yellow- Where the touch event is triggered.

Thanks ! Smiley

The Exceptionn was caused by the array list.in which you are trying to access the index which is out of range.

java.lang.IndexOutOfBoundsException: Invalid index 83, size is 83

This looks weird:

for (int j = 0; i < object.size(); j++) {

mixing up i and j ? This might be causing the index out of bounds error
