Invalidate() not calling onDraw

Question

Yesterday I asked a question pertaining to Android graphics, and now that I have the basis up and running, I've made a rendering loop inside of my custom view class.

protected void render() {
    long startTime = System.nanoTime();
    long elapsedTime;
    while (Main.running) {
        Bitmap image = Bitmap.createBitmap(Main.WIDTH, Main.HEIGHT, null); //creates new Bitmap to draw onto
        Canvas canvas = new Canvas(image); //new Canvas with the attached blank Bitmap
        long newTime = System.nanoTime();
        elapsedTime = newTime - startTime;
        if (elapsedTime >= 1000000000/60) { //if enough time has passed for it to update
            startTime = newTime;
            Main.player.render(canvas); //this renders a test object, see below
        }
        display = Bitmap.createBitmap(image); //this writes to the display Bitmap that is drawn in onDraw, see below
        invalidate(); //invoke onDraw()
    }
}

Here is the code for drawing my player image (which DOES work if I draw it once rather than in a loop.)

public void render(Canvas c) {
        int xp = (int) x;
        int yp = (int) y;
        c.drawBitmap(Images.box, xp, yp, null);
    }

And inside onDraw:

@Override
    protected void onDraw(Canvas canvas) {
        super.onDraw(canvas);
        canvas.drawBitmap(display, 0, 0, null);
    }

If I just render the player and call invalidate() once, rather than looping it multiple times, it displays fine (and dandy). However, when I put it in the loop block it does not render.

According to my logging, the loop is functional and calls invalidate(), but it never actually enters the onDraw method during the loop.

If anybody could explain why this is happening that would be very grand, and if you need more information please let me know and I will provide.

EDIT: In my main Activity class, I have a thread for game logic and then enter the render loop with the main thread after starting the logic thread.

Thread update = new Thread() { //game logic thread
            public void run() {
                loop(); //game logic loop
            }
        };
        update.start(); //start logic thread
        surface.render(); //start render loop (surface is the name of my custom view)

I have tried making a separate thread for rendering and entering the game loop with my main thread, however that still did not work.
