Insufficient Permission when run youtube retriving comments

Question

This is my whole code. I want to give a video ID which from youtube to get the comments related to this vedio ID.　But always show that I have Insufficient Permission.

Answer 1

You only need a key to retrieve comments. Something like this:

String apiUrl = "https://www.googleapis.com/youtube/v3/commentThreads?part=snippet%2Creplies&videoId=" + ytId + "&moderationStatus=published&order=relevance&maxResults=5&key=" + apiKey;

Then handle the Json response.
