Android force closing app on particular image. How can I track the issue down?

Question

I'm trying to display 2 images on a canvas. I've loaded one, and it works fine. The second I've created, loaded and am displaying in the same manner, but the app force closes each time.

Both images are PNGs and are in res/drawable-mdpi.

Loading images:

private Bitmap stageBMP=BitmapFactory.decodeResource(getResources(), R.drawable.stagel);
private Bitmap magBMP = BitmapFactory.decodeResource(getResources(), R.drawable.mag);

Displaying images:

canvas.drawBitmap(stageL, 300,300, null);
canvas.drawBitmap(magBMP, 300,300, null);

If I comment out the final line, the app loads (displaying only the first image). Instead of displaying magBMP I show stageL twice, it works.

Working image:

Incompatible image:

Answer 1

OK, I managed to find a solution.

Instead of loading images in one class and passing them to another to be displayed, I passed the context to the second class, and loaded them and displayed them there.

I confess I don't really understand why this should work, but for a scrappy solution it'll do for now.
