ANDROID: Help, outofmemory bitmap exceeds budget size. how to recycle?

I've hit a wall with my Android-app, as I'm getting an OutOfMemoryException with the description that my "bitmap exceeds VM budget" and so on. The weird thing is that the code works on one PC but triggers this exception in another.

I have like 10 900x500 images and the code I'm using is enclosed below. I have tried to recycle(), which renders both the errors and the images invisible. I really need help with this. Thanks in advance:)

You should call recycle() on the Bitmap after you've added the Bitmap to your ImageView. Works for me.
