Crash when calling pause(): IllegalStateException: cache is closed

[glennschmidt]

TileView causes a crash for me when i suspend my app and call the pause() method.

The TileView is being presented by a fragment and the sequence of events is:

1. User presses device home button
2. Activity.onPause()
3. Fragment.onPause()
4. TileView.pause()
5. Crash

The crash doesn't happen if I don't call TileView.pause(), but i imagine that will lead to other problems.

Is there something i am forgetting to do? The trace is:

I'm using
tileviewlib-1.0.12
disklrucache-1.3.1

Thanks for posting. Looks like I'm not appropriately handling the cache at some point.

I'll try to get a patch pushed soon, but not sure when that'll be. For now, I'd suggest simply disabling cache if that a possibility for you.

Does this happen on a range of devices or images, or just one? Do you see it in the emulator, on a real device(s), or both?

It happens on both a real device and emulator.
I will disable caching for now.

This is corrected in the latest commit (really just needed be less strict on what exceptions were caught). Note that I have not released a new .jar, you'll need to grab the source, nor have I updated the docs (just moved to AS from Eclipse, which had those tasks pretty well baked-in, still getting used to AS).
