Guys, Digging a bit further into this, turns out that my generated JAR file looks exactly like the other ones that are generated by the build, so I guess I'm OK there. I was looking in the Android/out/target/product/<name>/system/framework directory. Now my question is where is the JAR file from my build for my custom API that I can send to a application developer so that they can point Eclipse at it to get access to the API?
