Hello guys

I have a question about the chatter.

so far, I want to use chatter rest API to sent real time message to the users.

After do some research, I know it is easy to do this on the web page

But how to do the same things from the Android app?

below link is to show how to send message from the web page.

Could anybody can help me about this. thanks so much.

ps: in other hand, I can use mobile app to invoke the APEX class,

Know how to send real time message in APEX class also can resolve my question.
