Every experts in Android Development. I need your help!
I'm developing an android application in which the user can record a video and subsequently upload the video to Youtube.

I have read a lot of information Youtube Data API documentation and have no clues how to make it.
I created a api key for Youtube Data API (Oauth).
I also know I need to use Google APIs Client Library for Java.
However, how to use it in Android?

It seems like there are no much videos or tutorials for implementing an app which can upload video to Youtube directly.

If you guys can help, I will appreciate it so much. Many Thanks!
