回答1:

Youtube API allows you to search & list videos and obtain the mediaplayer URL, so that you can play videos within your web page.

Look here for downloading video from Youtube

Youtube Video Data API

Youtube Java Data API - Getting Started

It does not allow you to download the byte content of videos - because Google is protecting their own rights and the rights of the content creators.

I am late but this solution is best for me just try this.

METHOD 1

Add into your gradle file

 allprojects {
        repositories {
            maven { url "https://jitpack.io" }
        }
    }

And dependencies

 compile 'com.github.Commit451.YouTubeExtractor:youtubeextractor:2.1.0'

Add this small code and you done. Demo HERE

public class MainActivity extends AppCompatActivity {

    private static final String YOUTUBE_ID = "ea4-5mrpGfE";

    private final YouTubeExtractor mExtractor = YouTubeExtractor.create();


    private Callback<YouTubeExtractionResult> mExtractionCallback = new Callback<YouTubeExtractionResult>() {
        @Override
        public void onResponse(Call<YouTubeExtractionResult> call, Response<YouTubeExtractionResult> response) {
            bindVideoResult(response.body());
        }

        @Override
        public void onFailure(Call<YouTubeExtractionResult> call, Throwable t) {
            onError(t);
        }
    };


    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);


//        For android youtube extractor library  com.github.Commit451.YouTubeExtractor:youtubeextractor:2.1.0'
        mExtractor.extract(YOUTUBE_ID).enqueue(mExtractionCallback);

    }


    private void onError(Throwable t) {
        t.printStackTrace();
        Toast.makeText(MainActivity.this, "It failed to extract. So sad", Toast.LENGTH_SHORT).show();
    }


    private void bindVideoResult(YouTubeExtractionResult result) {

//        Here you can get download url link
        Log.d("OnSuccess", "Got a result with the best url: " + result.getBestAvailableQualityVideoUri());

        Toast.makeText(this, "result : " + result.getSd360VideoUri(), Toast.LENGTH_SHORT).show();
    }
}

You can get download link in bindVideoResult() method.

METHOD 2

Using this library android-youtubeExtractor

Add into gradle file

repositories {
    maven { url "https://jitpack.io" }
}

compile 'com.github.HaarigerHarald:android-youtubeExtractor:master-SNAPSHOT'

Here is the code for getting download url.

       String youtubeLink = "http://youtube.com/watch?v=xxxx";

    YouTubeUriExtractor ytEx = new YouTubeUriExtractor(this) {
        @Override
        public void onUrisAvailable(String videoId, String videoTitle, SparseArray<YtFile> ytFiles) {
            if (ytFiles != null) {
                int itag = 22;
// Here you can get download url
                String downloadUrl = ytFiles.get(itag).getUrl();
            }
        }
    };

    ytEx.execute(youtubeLink);

You can try using my library, youtube-dl-android, which lets you to easily extract video link from 1000+ sites including YouTube, Facebook, etc.

Step 1: Add jitpack repository to your project build file

allprojects {
    repositories {
        maven { url 'https://jitpack.io' }
    }
}

Step 2: Add the dependency

dependencies {
    implementation 'com.github.bawaviki.youtube-dl-android:library:0.7.+'
}

Step 3: Use Youtube-dl instance

YoutubeDLRequest request = new YoutubeDLRequest("http://youtube.com/watch?v=xxxx");
request.setOption("-o", youtubeDLDir.getAbsolutePath() + "/%(title)s.%(ext)s");
YoutubeDL.getInstance().execute(request, (progress, etaInSeconds) -> {
    System.out.println(String.valueOf(progress) + "% (ETA " + String.valueOf(etaInSeconds) + " seconds)");
});
