Android First-look: Twitroid
Although the first official release will not be available until Monday (and the devs expect it in the Android Market shortly after), you can download the 0.7 pre-release version from twitroid.mobi. First, you need to enable "Unknown Sources" in the Applications settings on your device (Settings > Applications > check "Unknown Sources"), but after that, it is a simple OTA installation.
Because Twitroid was still in beta at the time of my test, I'm not going to grouse over the error messages and some of the quirk I experienced, but I do want to point out that those bugs did not negatively impact the rest of the device or any of its software. When the app crashed (really, I got a time-out message and was forced to choose "Force close"), the rest of the device continued to work swimmingly. Actually, Twitroid still continued to work, I just got a lot of "not responding" messages. After covering and reading about so many bugs and crashes in pre-2.1 iPhone firmware for TUAW, this was a bit of a relief. Even if something crashes, it does not appear to be the end of the world.
Aside from any beta bugs, Twitroid is a very nice Twitter client. It provides an easy way to send messages, take pictures and send those as messages (though the G1's camera didn't want to cooperate with me to send a non-blurry photo for an adequate test), access and reply to direct messages and even search search.twitter.com. By default, it automatically checks for new tweets every 3 minutes, though you can refresh that manually.
All in all, it is a solid first step for a Twitter client, and I look forward to playing with the first official release next week. A side note -- the actual mobile web interface for Twitter looks fantastic on Android's WebKit broswer. Readable, clean and very, very nice. While I still think a Twitter client is helpful for people who have lots of followers or want to manage more features, it is nice to know that the web interface is a step-up from the BlackBerry interface, anyway.
