Hello, I looked into this issue on a previous occasion for a different user, and I can tell you what I told them. Essentially, these APIs were not designed to work on Android, and they don't work on Android as you have experienced above.
That said, you might be able to get it to work using one of these: 1. Include the source code for the java client library directly in your project. You'll still need to include the extra external jars needed with the client library (mail.jar, activiation.jar) but that might work. 2. Use the google-api-java-client. They claim to have an example with the picasa API that works on Android, although I couldn't get it to work on my side. http://code.google.com/p/google-api-java-client/ 3. Don't use a client library, or use a client library to handle authentication and then write your own fetcher (just send a request to the URL you want, and parse the incoming json or XML). I would recommend strongly option 2 if you can get it work, or option 3 if you can't. It's a little more work to get away from the client libraries, but you'll have great freedom. Sorry I couldn't be of more help.
