Youtube视频无法播放2G或3G网络

Question

我创建了一个应用程序，我正在使用YouTube API播放youtube视频。通过wifi，它工作正常，但当我使用2g或3g网络播放时，它会显示错误消息“发生错误，触摸重试。”

这是我的YouTube API代码。

package com.example.userone.asianconnections.Activity;

import android.app.ActionBar;
import android.content.Intent;
import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.support.v7.widget.Toolbar;
import android.util.Log;
import android.widget.Toast;

public class YouTubeVideoActivity extends YouTubeBaseActivity implements YouTubePlayer.OnInitializedListener {


    private static final int RECOVERY_REQUEST = 1;
    private YouTubePlayerView youTubeView;
    String video_url;

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

        youTubeView = (YouTubePlayerView)findViewById(R.id.youtubevideoId);
        youTubeView.initialize(Config.YOUTUBE_API_KEY, this);

        Intent intent = getIntent();
        video_url = intent.getStringExtra("videoLink");

        Log.e("link is ", video_url+"");

    }

    @Override
    public void onInitializationSuccess(YouTubePlayer.Provider provider, YouTubePlayer youTubePlayer, boolean b) {

        if(!b){
            youTubePlayer.cueVideo(video_url);
        }
    }

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

        if(!youTubeInitializationResult.isUserRecoverableError()){

            youTubeInitializationResult.getErrorDialog(this, RECOVERY_REQUEST).show();
        }else{
            String error = String.format(getString(R.string.player_error), youTubeInitializationResult.toString());
            Toast.makeText(this, error, Toast.LENGTH_LONG).show();
        }
    }


    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);

        if(requestCode == RECOVERY_REQUEST){

            getYouTubePlayerProvider().initialize(Config.YOUTUBE_API_KEY, this);
        }

    }
    protected YouTubePlayerView getYouTubePlayerProvider() {
        return youTubeView;
    }

    private void showMessage(String message) {
        Toast.makeText(this, message, Toast.LENGTH_LONG).show();
    }




    private final class MyPlaybackEventListener implements YouTubePlayer.PlaybackEventListener {

        @Override
        public void onPlaying() {

        @Override
        public void onStopped() {
            // Called when playback stops for a reason other than being paused.
            showMessage("Stopped");
        }

        @Override
        public void onBuffering(boolean b) {

        }

        @Override

            // Called when a jump in playback position occurs, either
            // due to user scrubbing or call to seekRelativeMillis() or seekToMillis()
        }
    }

    private final class MyPlayerStateChangeListener implements YouTubePlayer.PlayerStateChangeListener {

        @Override
        public void onLoading() {
            // Called when the player is loading a video
            // At this point, it's not ready to accept commands affecting playback such as play() or pause()
        }

        @Override
        public void onLoaded(String s) {
            // Called when a video is done loading.
            // Playback methods such as play(), pause() or seekToMillis(int) may be called after this callback.
        }

        @Override
        public void onAdStarted() {
            // Called when playback of an advertisement starts.
        }

        @Override
        public void onVideoStarted() {
            // Called when playback of the video starts.
        }

        @Override
        public void onVideoEnded() {
            // Called when the video reaches its end.
        }

        @Override
        public void onError(YouTubePlayer.ErrorReason errorReason) {
            // Called when an error occurs.
        }
    }
 }

这是我的布局XML文件
