I've tracked the problem down to a rather odd place: Handler. The first post networking call is kicked off on a separate thread when the user clicks a button. When this call returns its result, a Handler is spawned to update the UI and also download the image data for display in a newly created ImageView. If the file download Thread is started from within the Handler's Runnable, I get the error described above. HOWEVER if I spawn the thread outside the Handler's Runnable, then all works well. Sadly...I need to make the call from with the Handler is that's where my ImageView is created.
SO I'm stuck at the moment. I don't see why spawning a Thread inside a Handler's Runnable callback should be a problem as I should then be on the main thread. Curiously I can use Drawable.createFromStream(new URL(url).getContent()) to create my Drawable without a problem. I guess Android's own code knows a workaround to my bug. However I actually need the image data for storage to a file first so that Drawable solution won't work for me. Time to dig into Android's code to see why Drawable.createFromStream (new URL(url).getContent()) works inside the Handler while mine doesn't.
