Question: Hey all. I need to work on all of the skills that come along with working with web services in Android. Most of the apps I've worked on have used static/local data. Obviously, to create something powerful, I need to learn how to work with web services. 

To that end, does anyone have any recommendations for an easy API to work with? I don't really have any preference (I'm doing this project just so I can learn), though I'd rather not work with Twitter.

So, I'm looking for one of the popular APIs, but something that's relatively simple so that I don't have to be bogged down in an ultra-complex API. I want to be able to focus more on the Android/Java implementation. 

Thanks a lot!

Answer: 
You have many API that you can use to leverage your skills. Facebook is one of them but you can also have a look at websites such as Read It Later, Instapaper, Delicious or MeeGo that use simple web API with JSON/XML to transmit data.
First web API I used was Flickr. They have great documentation, most (all?) of the data can be returned in JSON format, and it's pretty expansive. I thought it was pretty simple to use, myself.
