I had been hard coding a collision detection system which was buggy. Then I came across using rectangles for collsion detection. So I put it all in and it does not work, I put a log in and it never logged.

Note to Java programmers who are not Android programers: Android uses the word Rect instead of Rectangle.

Code for Block.java:

public Rect getBounds(){
    return new Rect (this.x, this.y, 10, 20);
}

Code for Sprite.java:

public Rect getBounds(){
    return new Rect (this.x, this.y, 20, 20);
}

Code for MainGame.java:

for(Block block : BLOCKS) {
    block.draw(canvas);
    block.rigidbody();

    Rect spriter = sprite.getBounds();
    Rect blockr = block.getBounds();

    if(spriter.intersect(blockr)){
        showgameover = 1;
        Log.d(TAG, "Game Over");
    }

}

Is anyone able to help?
