VideoView无法播放片段

Question

VideoView无法播放带有片段的视频，我创建了一个片段，为什么要使用ButtonNavigationView。这是源代码，请帮助我，我没有发现错误：

package mediaser.tivvmialive;

import android.net.Uri;
import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.MediaController;
import android.widget.VideoView;

public class Home extends Fragment {

    public static Home newInstance() {
        Home fragment = new Home();
        return fragment;
    }

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
    }


    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {

        View view = inflater.inflate(R.layout.activity_home, container, false);
        VideoView videoView = view.findViewById(R.id.videoView);
        Uri video = Uri.parse("http://rumblehwk.altervista.org/VideoHome/default.mp4");
        videoView.setVideoURI(video);
        videoView.start();
        return inflater.inflate(R.layout.activity_home, container, false);


    }
