How get the thumbnail from YouTube

Question

Thumbnail from the video in YouTube.

I want to add the ability to add images from video which I get in my method useLinkInput.

Now I have a dialog, where I have the following code:

public void onClick(DialogInterface dialog, int which) {
    dialog.dismiss();
    Toast.makeText(getContext(), "ОК", Toast.LENGTH_SHORT).show();
    String string = input.getText().toString();
    useLinkInput(string);
}

And method useLinkInput:

private void useLinkInput(String input) {
    Uri uri = Uri.parse(input);
    String videoID = uri.getQueryParameter("v");
    url = "http://img.youtube.com/vi/" + videoID +"/0.jpg";
    Log.d("url", url);
}

When the user pastes the link in the dialog and presses OK, I get this in the log image:

D/url: http://img.youtube.com/vi/null/0.jpg

But it is null* (it didn’t show the image).

Why would you not want to use it? It is specifically built to do things exactly like this. — Charles McKelvey, Oct 03 '16 at 12:04

For example, your YouTube video URL is as below.

String youtubeUrl = "https://www.youtube.com/watch?v=Rxo0Upfz48Q";

In this URL parameter, v=Rxo0Upfz48Q stands for the video ID. So, in the above URL videoID is Rxo0Upfz48Q.

You can get videoID using the below code.

Uri uri = Uri.parse(youtubeUrl);
String videoID = uri.getQueryParameter("v");

Now using videoID you can make the URL to get the first frame of that YouTube video like below.

String url = "http://img.youtube.com/vi/" + videoID + "/0.jpg";

Now you can get a thumbnail image from the above URL and display in your imageview.

But if i need to get every time random url? – Morozov Oct 03 '16 at 12:10
As I have described in answer you can make random thumbnail url using VideoID. And you can parse VideoID by `uri.getQueryParameter("v")` from your youtube url. Check my updated answer. – Priyank Patel Oct 03 '16 at 12:16
