The problem is :
I can use appcfg.py to upload the python programe, and also can update
success. When I use the app engine to register a android client gmail,
It is success, and I can find the registered account in the app engine
server, but when I use the python in server to send message to android
client , It occured the fault that Unauthorized Error 401.
I use this programe on another my google appengine account ,It is
right , all is successful.
So I don't know what is wrong with this egine.
In another App engine of mine, I use the same programe with this app
engine account, but everything is ok.
Can someone tell me why, or give me some advices.
The server python programe is :
