Yeah, I gave up on mine months ago and moved to BitcoinSpinner.
I've used both but it looks like I'm forced to stop using this one because it just doesn't work very well.

I've had some problems with this wallet recently. Downloading and processing the blockchain seems really slow and I get crashes all the time. I've been using this wallet for a long time and I've not had these problems before.
It connects to nodes just fine but the download seems slower and it stalls way more and I get crashes much more often. My phone otherwise has no problems and there have been no changes to my phone's software.

You need to process transactions in order to have a consistent wallet. And Bitcoin cannot serve the chain backwards in an efficient manner anyway.
At this point the time goes almost exclusively on:
a) Parsing the blocks
b) Writing data to disk
For (a) we plan to implement an Aho-Corasick scanner once we have a real blockchain API, which should kill off parsing time almost entirely because you'll only have to parse blocks that actually contain relevant transactions. Longer term we can push block filtering into the protocol/Satoshi client to eliminate network speed as an issue as well, but it's not really a problem today.
For (b) there are some simple optimizations we can make once the library is in charge of saving the wallet instead of the library user. Phone storage latency is poor and unpredictable. Batching writes can help a lot.
So there is a plan and it will get executed at some point. These things just take a while.

It's possible to get chain download speed up dramatically, fast enough that you won't really notice it in future. However more work is required.
someone's probably already thought of this and posted elsewhere, but what if you could somehow download it in reverse? start with the most recent blocks and work backwards. the further back you go, the more you can trust the recent blocks as valid.

I just posted some feature requests in the Bitcoin Spinner thread but since it applies to any mobile app I'll link to it here as well:

But anyway, I really appreciate the work both of you are putting in to your clients. And I absolutely love the design and layout of your app. Mobile apps are the way to go to promote bitcoin.
The thing that is really holding me back from using your app though, is the need to download the block chain. This particularly holds me back from promoting your app to others since I want to show people the ease of use with bitcoin and the waiting period kind of puts people of. So I'm wondering what your future plans are regarding this and if I can look forward to a future light weigth client with your design and features.

The newer version of Android Wallet download the blockchain much quicker than old versions did. In addition, I believe they are working on an even faster method but I don't know timeframe on that. If at all possible, download the blockchain over wifi, you'll get much better results.

The app does make backups of the wallet. if you browse to /data/data/de.schildbach.wallet, there should be multiple copies of your wallet. That data survives an app uninstall.
While yes, your private keys (not the whole wallet) are backed up multiple times to the quoted location, I'm afraid they won't survive app uninstall. Afaik, Android removes the complete app directory under /data/data - but I may be wrong.
The app itself was gone? And you're sure you didn't uninstall it?
That's really weird.
That's really weird.
exactly. of course i didn't uninstall it.
in fact, i downloaded it to try b/c you had just released the new version of BitcoinJ to it and MultiBit so i thought i'd better give it a try.
if you have any suggestions about how i could be a dummy please feel free to suggest but the whole thing is gone.

i had to go to the backup and click on it to discover the above solution. my phone isn't rooted either.
i may have found the problem except i can't verify right now b/c my phone is on low power.
i didn't have a box checked that would allow me to download "unknown apps outside the Android Market". this i find weird b/c despite that i was able to initially download app with blockchain and test it from Android Market. once i checked box it asked me to reinstall over old install. checked yes and app popped back up with 1 BTC in it. thats when my power went dead.
so i think it will be ok.

Afaik the private key of the wallet is stored into a secure folder on the phone. 3rd party software or malware can't access this folder unless you have your phone rooted.

Malware on android that completely uninstalls an app? That would be a new one.

I'd suggest anyone thinking about using this software (or any wallet software) to invest in a backup app. I use Titanium Backup Pro and it has saved me multiple times when upgrading/downgrading/etc.

WARNING!!!!
installed this on my Android a couple of days ago along with 1 BTC. tonite the 1 BTC and entire installation gone from my phone.
everything else on the phone seems intact but i can only assume some malware took the wallet. too bad. was looking forward to using this; i'd heard alot about it.

is it still being worked on? i used it a few months ago but uninstalled it.
Yes, he did a fix for me last month when I was having feb 12th trouble and then released the newer version with NFC not very long ago.
