I want to build a AppEngine GWT RPC app connected with an Android project with the RPC calls enabled between the server, GWT interface and the Android device. I know that is possible, but I still couldn't figure out how to do it. Can anyone explain to me how to do it? And maybe provide an example?
I've already tried gwt-syncproxy (https://code.google.com/p/gwt-syncproxy/), but I didn't understand how to login to AppEngine. The example given and the library provided does not correspond.
Best How To :
I'm still working on a more formative tutorial since taking over the GWT-Syncproxy project, so sorry for the confusion. As you noted, the examples on the front page to not correspond to the Android library. Those methods are meant for the java standalone library usage.
In the meantime, Focus on the Android wiki for implementation instructions. The source code also has an example app implemented for testing purposes, but it gives a relatively simple example of how to use the library. I'll hopefully have a better tutorial up and running by end of the summer or so.
