Youtube player API Access denied finding property

Iam trying to build simple youtubeplayer android app, after running my code on my physical device the app runs successfully but the video remains in loading mode, When i checked my logcat i found some issues maybe related or causes this problem:

And this is the code i run:

package Thrax.com;
import androidx.appcompat.app.AppCompatActivity;
import androidx.constraintlayout.widget.ConstraintLayout;
import android.os.Bundle;
import android.view.ViewGroup;
import android.widget.Button;
import android.widget.Toast;
import com.google.android.youtube.player.YouTubeBaseActivity;
import com.google.android.youtube.player.YouTubeInitializationResult;
import com.google.android.youtube.player.YouTubePlayer;
import com.google.android.youtube.player.YouTubePlayerView;
public class YoutubeActivity extends YouTubeBaseActivity implements YouTubePlayer.OnInitializedListener
{
static final String GOOGLE_API_KEY = "Implement my google API_KEY HERE";
static final String YOUTUBE_VIDEO_ID = "ZnZsVLiVPLs";
static final String YOUTUBE_PLAYLIST = "PLzcK7AwShFBmc0Pigajs_u5nhQIwARAmE";
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
//        setContentView(R.layout.activity_youtube);
//        ConstraintLayout constraintLayout = (ConstraintLayout) findViewById(R.id.activity_youtube);
ConstraintLayout layout = (ConstraintLayout) getLayoutInflater().inflate(R.layout.activity_youtube, null);
setContentView(layout);
//        Button button1 = new Button(this);
//        button1.setLayoutParams(new ConstraintLayout.LayoutParams(360,100));
//        button1.setText("Button_Dynamic");
//        layout.addView(button1);
YouTubePlayerView playerView = new YouTubePlayerView(this);
playerView.setLayoutParams(new ConstraintLayout.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT , ViewGroup.LayoutParams.MATCH_PARENT ));
layout.addView(playerView);
playerView.initialize(GOOGLE_API_KEY , this);
}
@Override
public void onInitializationSuccess(YouTubePlayer.Provider provider, YouTubePlayer youTubePlayer, boolean b) {
}
@Override
public void onInitializationFailure(YouTubePlayer.Provider provider, YouTubeInitializationResult youTubeInitializationResult) {
final int REQUEST_CODE = 1;
if(youTubeInitializationResult.isUserRecoverableError()){
youTubeInitializationResult.getErrorDialog(this , REQUEST_CODE).show();
}
else{
String errorMessage = String.format("There was a error initializing Youtube player (%1$s)" , youTubeInitializationResult.toString());
Toast.makeText(this , errorMessage , Toast.LENGTH_LONG).show();
}
}
}

将你的`onInitializationSuccess()`方法更改为以下内容：
```java
@Override
public void onInitializationSuccess(YouTubePlayer.Provider provider, YouTubePlayer youTubePlayer, boolean b) {
youTubePlayer.setPlayerStateChangeListener(playerStateChangeListener);
youTubePlayer.setPlaybackEventListener(playbackEventListener);
if (!b) {
youTubePlayer.cueVideo(VIDEO_ID);
}
}

然后创建以下方法，用于实现playerStateChangeListener()和playbackEventListener()：

private YouTubePlayer.PlayerStateChangeListener playerStateChangeListener = new YouTubePlayer.PlayerStateChangeListener() {
    @Override
    public void onLoading() {

    }

    @Override
    public void onLoaded(String s) {

    }

    @Override
    public void onAdStarted() {

    }

    @Override
    public void onVideoStarted() {

    }

    @Override
    public void onVideoEnded() {

    }

    @Override
    public void onError(YouTubePlayer.ErrorReason errorReason) {

    }
};

private YouTubePlayer.PlaybackEventListener playbackEventListener = new YouTubePlayer.PlaybackEventListener() {
    @Override
    public void onPlaying() {

    }

    @Override
    public void onPaused() {

    }

    @Override
    public void onStopped() {

    }

    @Override
    public void onBuffering(boolean b) {

    }

    @Override
    public void onSeekTo(int i) {

    }
};

应该可以正常工作。

@Override
public void onInitializationSuccess(YouTubePlayer.Provider provider, YouTubePlayer youTubePlayer, boolean b) {
youTubePlayer.setPlayerStateChangeListener(playerStateChangeListener);
youTubePlayer.setPlaybackEventListener(playbackEventListener);
if (!b) {
youTubePlayer.cueVideo(VIDEO_ID);
}
}

private YouTubePlayer.PlayerStateChangeListener playerStateChangeListener = new YouTubePlayer.PlayerStateChangeListener() {
@Override
public void onLoading() {
}
@Override
public void onLoaded(String s) {
}
@Override
public void onAdStarted() {
}
@Override
public void onVideoStarted() {
}
@Override
public void onVideoEnded() {
}
@Override
public void onError(YouTubePlayer.ErrorReason errorReason) {
}
};
private YouTubePlayer.PlaybackEventListener playbackEventListener = new YouTubePlayer.PlaybackEventListener() {
@Override
public void onPlaying() {
}
@Override
public void onPaused() {
}
@Override
public void onStopped() {
}
@Override
public void onBuffering(boolean b) {
}
@Override
public void onSeekTo(int i) {
}
};
