Android: Fehler beim Initialisieren des Youtube-Players

Question

Ich implementiere einen YouTube-Player in meiner App mit YouTubeAndroidPlayerApi zum Abspielen von Videos, die ich in meine App hinzufüge. Es lief alles gut bis vor zwei Tagen, als plötzlich ein Fehler auftauchte. Ich habe versucht, das zu lösen, aber habe versagt. Bitte hilf mir.

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); 
    } 

}

Kann jeder Punkt heraus, was das Problem ist. Danke im Voraus.

Answer 1

Hatten Sie Google Youtube App auf Ihrem Gerät?

Update youtube App von Playstore auf die neueste, oder Sie können es installieren, wenn Sie nicht haben. dann führen Sie die Youtube App,

letzten Schritt, versuchen Sie, Ihre eigene App mit youtube Player wieder zu laufen. Sag mir, wenn es funktioniert.
