wechat android sdk,Getting Started with the WeChat Android SDK

I have downloaded the SDK example from WeChat website: http://dev.wechat.com/document/gettingstart/android/

I used Eclipse and ADT, target platform Android 2.2 on Samsung Galaxy Spica i5700.

The problem is that the provided demo application is only capable of starting WeChat messenger, while all other function calls do not make any effect on WeChat app.

I was debugging through Eclipse and I saw that API calls to WeChat return success, but weChat is not really responding to any request from the demo app. For example, if I want to share text on "Moments" or to send an image to current scene (chat session), nothing happens, but also no error occurs.

Has anyone made it work this demo application?

Thanks.
