Reading this post on how to avoid OutOfMemory (OOM) triggered a little search for places where Bitmaps might be causing trouble. In one place the following seemed to be in need of update:

//fOut is a FileOutputStream
mBitmap = BitmapFactory.decodeStream(url.openStream());
mBitmap.compress(Bitmap.CompressFormat.PNG, 100, fOut);

This downloads a bitmap and saves it to a stream. (Don’t use this code. the openStream has no timeout, so you will get funky stuff when your stream doesn’t work like you’d like it to).

Looking for a simple way to do that decodeStream with a Drawable instead of a BitmapFactory gave me no help. I did find this post on the google groups: Store drawable locally as a file . This in turn links to this excellent howto.

Just a minor addition from my side if you are using that code on Android:

FileOutputStream out = new FileOutputStream(name);

That’s all fun and games, untill someone loses an eye. Or tries to read the file :) Be sure to make that file readable enough for your convenience and all, so use the openFileOutput from your context:

FileOutputStream out = openFileOutput(name, Context.MODE_WORLD_READABLE);
