[考试]的Andr​​oid Videoview只能使用本地文件 [英] [Java]Android Videoview works only with local files

问题描述

我试图从URL播放视频，但只有本地视频作品在我的code。如果我尝试从URL我的Nexus 7显示屏打开视频
无法播放这部影片。这里是code本地文件的播放，它工作正常（两者是相同的视频）

I tried to play a video from a url, but only local videos works in my code. If I try to open a video from a url my nexus 7 displays Can not play this video. Here is the code for the playback of a local file, it works fine (both are the same videos)

package com.sample.prog;

import java.io.File;

import android.app.Activity;
import android.os.Bundle;
import android.os.Environment;
import android.widget.VideoView;
import android.net.Uri;

public class MainActivity extends Activity {

    static private final String pathToFile = "bigbuck.mp4";
    private VideoView videoPlayer;

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

        File root = Environment.getExternalStorageDirectory(); 

        videoPlayer = (VideoView) findViewById(R.id.videoPlayer);   
        videoPlayer.setKeepScreenOn(true);    
        videoPlayer.setVideoPath(root + "/" + pathToFile);
        videoPlayer.start();
    }
}
