Embedding a Youtube video in Android Activity

Question

I am embedding a Youtube video in my Android app. I have been reading several blog, posts, etc. and I am a little bit lost. My layout is

<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.ConstraintLayout 
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="horizontal"
    android:theme="@style/Theme.AppCompat.NoActionBar"
    tools:context=".UD1">

    <com.google.android.youtube.player.YouTubePlayerView
        android:id="@+id/youtubePlayerView"
        android:layout_width="715dp"
        android:layout_height="461dp"
        android:layout_marginTop="8dp"
        app:layout_constraintBottom_toBottomOf="parent"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintTop_toTopOf="parent"
        app:layout_constraintVertical_bias="0.0" />

</androidx.constraintlayout.widget.ConstraintLayout>

The activity that I have created is:

public class UD1 extends YouTubeBaseActivity {
    String APIkey = "aavvss";
    String video1 = "hjFaqDNUVFo";
    String video2 = "41cJ0mqWses";
    String video3 = "uT8-YdXPNBk";
    String video4 = "vSdAv931s-g";


    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.ud1);
        final YouTubePlayerView youtubePlayerView = findViewById(R.id.youtubePlayerView);
        playVideo(video1, youtubePlayerView);

    }

    public void playVideo(final String videoId, YouTubePlayerView youTubePlayerView) {
        //initialize youtube player view
        youTubePlayerView.initialize(APIkey,new YouTubePlayer.OnInitializedListener() {
                @Override
                public void onInitializationSuccess(YouTubePlayer.Provider provider,
                                                    YouTubePlayer youTubePlayer, boolean b) {
                    youTubePlayer.cueVideo(videoId);
                }

                @Override
                public void onInitializationFailure(YouTubePlayer.Provider provider,
                                                    YouTubeInitializationResult youTubeInitializationResult) {

                }
            });
}

}

When I run the application I get the following exception:

Caused by: java.lang.IllegalStateException: A YouTubePlayerView can only be created with an Activity which extends YouTubeBaseActivity as its context.

However, my activity already extends YouTubeBaseActivity. As said, I have read several blogs, including StackOverflow and I didn't solve the error. Could please anyone guide me?

Thanks in advance

Answer 1

Finally, the solutions has been easier. In the layout, I was using a theme

android:theme="@style/Theme.AppCompat.NoActionBar"

Well, by removing the theme, Youtube player loads perfectly.

Answer 2

The Youtube Initialization is not happening properly in your Activity. Change your activity like this.

public class UD1 extends YouTubeBaseActivityextends YouTubeBaseActivity implements
        YouTubePlayer.OnInitializedListener {

    String APIkey = "aassvv";
    String video1 = "hjFaqDNUVFo";
    String video2 = "41cJ0mqWses";
    String video3 = "uT8-YdXPNBk";
    String video4 = "vSdAv931s-g";

    private static final int RECOVERY_DIALOG_REQUEST = 1;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.ud1);
        final YouTubePlayerView youtubePlayerView = findViewById(R.id.youtubePlayerView);
        // Initializing your video player like this
        youtubePlayerView.initialize(APIkey, this);

    }

    @Override
    public void onInitializationFailure(YouTubePlayer.Provider provider,
            YouTubeInitializationResult errorReason) {
        if (errorReason.isUserRecoverableError()) {
            errorReason.getErrorDialog(this, RECOVERY_DIALOG_REQUEST).show();
        } else {
            Toast.makeText(this,  errorReason.toString(), Toast.LENGTH_LONG).show();
        }
    }

    @Override
    public void onInitializationSuccess(YouTubePlayer.Provider provider,
            YouTubePlayer player, boolean wasRestored) {
        if (!wasRestored) {

            player.loadVideo(video1);

            // Hiding player controls
            player.setPlayerStyle(PlayerStyle.CHROMELESS);
        }
    }

    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        if (requestCode == RECOVERY_DIALOG_REQUEST) {
            // Retry initialization if user performed a recovery action
            getYouTubePlayerProvider().initialize(APIkey, this);
        }
    }

    private YouTubePlayer.Provider getYouTubePlayerProvider() {
        return (YouTubePlayerView) findViewById(R.id.youtubePlayerView);
    }
}
