Question

我想在我的android视频中播放youtube视频，当我在nexus 4.4设备中运行应用程序时，我得到＆＃34; 无法播放此视频错误＆＃ 34;而且我得到媒体播放器错误，过去两天我尝试但仍然没有成功。这是我的课堂活动代码我的要求是在视频中播放视频，而不是在youtube播放器中播放视频，所以请仅为视频导航我

public class MainActivity extends Activity {
    private VideoView videoView;
    private MediaController mController;
    private Uri uriYouTube;

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

        videoView = (VideoView) findViewById(R.id.videoView1);
        mController = new MediaController(this);

        videoView.setMediaController(mController);
        videoView.requestFocus();


        if (savedInstanceState != null) {
            int loc = savedInstanceState.getInt("Loc");
            Log.i("Loaction: ", loc + "");
            uriYouTube = Uri.parse(savedInstanceState.getString("url"));
            videoView.setVideoURI(uriYouTube);
            videoView.seekTo(loc);


            videoView.setOnPreparedListener(new OnPreparedListener() {
                @Override
                public void onPrepared(MediaPlayer mp) {
                    Log.v("onPrepared", "ok");
                    mp.start();
                }
            });
        } else {
            RTSPUrlTask truitonTask = new RTSPUrlTask();
            truitonTask.execute("http://www.youtube.com/watch?v=2zNSgSzhBfM");
        }

    }

    void startPlaying(String url) {
        uriYouTube = Uri.parse(url);
        videoView.setVideoURI(uriYouTube);
        videoView.start();
    }

    @Override
    protected void onSaveInstanceState(Bundle outState) {
        super.onSaveInstanceState(outState);
        outState.putInt("Loc", videoView.getCurrentPosition());
        outState.putString("url", uriYouTube.toString());
    }

                            if (maps.containsKey("url"))
                                cursor = maps.get("url");
                            if (f.equals("1"))
                                return cursor;
                        }
                    }

                return urlYoutube;
            }
        }

        public String extractYoutubeId(String url) throws MalformedURLException {
            String query = new URL(url).getQuery();
            String[] param = query.split("&");
            String id = null;
            for (String row : param) {
                String[] param1 = row.split("=");
                if (param1[0].equals("v")) {
                    id = param1[1];
                }
            }
            return id;
        }
    }
