I am trying to load an image from the interwebz but I get a null pointer exception. Here is my code :

hScroll = (HorizontalScrollView) findViewById(R.id.hScroll);
iv = (ImageView) findViewById(R.id.imageView);

It's mostly in the thread where I handle it.
I have no idea what is going on and I have tried to look at other questions but none solved my problem. The image that I retrieve is OK, I mean, I do profilepic.getWidth() and it returns the actual accurate value.
