Get video id from youtube url using Android Youtube ApI v3

Question

I'm using Android Youtube API v3. My application plays youtube video. I want to get videoID from youtube url.
I see there are a lot of sample that uses pattern to parse the url to get the video ID.
But I'm afraid of this way will fail when youtube change their url in the future.
There are some formats of youtube video url:

Are there any API to get video ID from the url?
Thanks in advance.

Answer 1

Yes, as you already figured this out that it is not that simple to get the video ID of a youtube video because of the inconsistency. You need to include all the possible permutations and combinations in the PHP (or what ever language script) you are going to parse the URL using regular expressions.

This question has been asked previously on SO you can refer that and add your own logic to parse the URL. I am pasting the links of some of them:

Answer 2

It will return you the video id: watchLink ="https://www.youtube.com/watch?v=s6RPsaco-vA"

 public static String getVideoId(String watchLink){

     return watchLink.substring(watchLink.length() - 11);
}
