YouTube API : com.google.api.client.googleapis.json.GoogleJsonResponseException: 403 Forbidden

I am new to YouTube APIs. I have downloaded & imported yt-direct-lite youtube android project from github in my eclipse. Everything is fine. But, when I run the project it toast/pops up error message that :

[Error] Access not configured: The API (youTube Data API) is not enabled for your project. Please use google developer console to update your configuration.

However, I have already turned on Google+ API as well as YouTube Data API v3

Also, I have generated API key. All the things are fine but when It goes to sign in for google/gmail account in the project. Also, fires below exception.
