我使用 YouTubeAndroidPlayerApi 在我的应用中实施了一个YouTube播放器来播放我添加到我的应用中的视频。当错误开始突然显现时，它工作得很好，直到两天。我一直试图解决这个问题，但都失败了。请帮帮我。
的onCreate
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.youtube_lightbox);
final RelativeLayout relativeLayout = (RelativeLayout) findViewById(R.id.relativeLayout_youtube_activity);
relativeLayout.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
onBackPressed();
}
});
final YouTubePlayerView playerView = (YouTubePlayerView) findViewById(R.id.youTubePlayerView);
if (savedInstanceState != null) {
millis = savedInstanceState.getInt(KEY_VIDEO_TIME);
}
final Bundle extras = getIntent().getExtras();
if (extras != null && extras.containsKey(KEY_VIDEO_ID)) {
mVideoId = extras.getString(KEY_VIDEO_ID);
} else {
finish();
}
playerView.initialize(API_KEY, this);
}
onInitializationSuccess
@Override
public void onInitializationSuccess(YouTubePlayer.Provider provider, YouTubePlayer youTubePlayer, boolean b) {
mPlayer = youTubePlayer;
youTubePlayer.setFullscreenControlFlags(YouTubePlayer.FULLSCREEN_FLAG_CONTROL_ORIENTATION);
youTubePlayer.addFullscreenControlFlag(YouTubePlayer.FULLSCREEN_FLAG_CONTROL_SYSTEM_UI);
youTubePlayer.setOnFullscreenListener(new YouTubePlayer.OnFullscreenListener() {
@Override
public void onFullscreen(boolean b) {
isFullscreen = b;
}
});
if (mVideoId != null && !b) {
youTubePlayer.loadVideo(mVideoId);
}
if (b) {
youTubePlayer.seekToMillis(millis);
}
}

任何人都可以指出这个问题是什么。提前谢谢。
答案 0 :(得分：-1)
您的设备上是否有google youtube应用？
将youtube应用从Playstore更新到最新版本， 或者你可以安装它，如果你没有。 然后运行youtube app，
最后一步，再次尝试使用youtube播放器运行您自己的应用。 告诉我它是否有效。
