using twitter4j for integration to tweet in android

please tell me where can i find twitter4j sdk for android and at least one example how to implement log-in and tweet in andr开发者_高级运维oid application.

I have searched but not found the solution.

Here's an example of how to login and tweet using OAuth:

I don't think there is a "for Android" SDK per say, but the normal Twitter4J SDK should work just fine according to their site: http://twitter4j.org/en/index.html#download
There are code examples on the site as well: http://twitter4j.org/en/code-examples.html
