I don't think I saw this mentioned, but here's one called GolfCard that looks pretty good (the web site is a little bit under construction because they just came out with a new version with some big changes):

I've looked at all the ones listed in this thread and this one looks like one of the better ones. Golflogix looks good, but I don't like that you can't survey the courses yourself if you want, and it seems to require communication between the phone and the company server. I'm currently using Intelligolf on the Palm Centro, but I'm moving to an Android Phone soon. After looking at all the iPhone and Android Golf Apps, I still don't think any of them beat Intelligolf. I wish they would make an app for Android.
Here are some of the best things about Intelligolf, which I would like to see in an Android app. It has the most comprehensive statistics recording I've ever seen, and it has a separate app for your PC. So, you can sit at your computer and review all your rounds, or look at various charts and graphs of how you are improving. It's also completely independent from the company, which one of the best things about it. It means that if the company is gone tomorrow, you could still use the app the exact same way. It doesn't require you to sync your scores with the company server, or require any other type of communication with the company. Also, you can survey an unlimited number of courses yourself without the company. Another thing I like is that you can type in notes for every hole and for every round. It's great for keeping track of how to play a particular hole, or for noting certain things about a good or bad round. Lastly, it keeps all of your rounds on your phone and when you are playing, you can review your history of the hole you are on, like how many times you birdied, parred, or bogied, and what your best and worst score was. It's really an amazing piece of software, if your analytical about your game like I am.
GolfCard has some of the best statistics recording and presentation I've seen on a Android app, and it looks to be pretty independent of the company. You can email yourself the scorecard after the round in a spreadsheet or web format. It still looks like it's missing some of the features I mentioned, but I think I'll try it out when I get my phone...can't wait!
