Android – upload videos programmatically to Youtube

I'm trying to upload videos to YouTube programmatically. I've tried

YouTubeService service = new YouTubeService(clientID,developer_key);
service.setUserCredentials("email", "password");

However, it throws a serviceexception to explain com.google.gdata.util.authenticationexception: what happens when there is an error connecting to the login URI?

resolvent:

You do not appear to have set up authentication

I recommend using data API v3. This is a great Java upload example

I also used serviceintent to open an Android upload example (YouTube direct Lite). Check it out at will
