在Android设备上播放视频

我搜索了每个地方的每一处资源，我尝试了几乎所有的东西，但出于某种原因，我的android设备不想在应用程序上播放视频。我试图将格式更改为3gp和mp4，当我启动应用程序时，它只是说视频无法播放。视频在我的手机中我不知道是错误的路径还是别的什么！在Android设备上播放视频

这里是我的代码：

protected void onCreate(Bundle savedInstanceState) { 

     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_main); 

     VideoView vid = (VideoView) findViewById(R.id.video); 
     vid.setVideoPath("/Phone/Movies/INSTA_Segment_0_x264.mp4"); 
     vid.setMediaController(new MediaController(this)); 
     vid.start(); 
     vid.requestFocus(); 
    }

    //we use onSaveInstanceState in order to store the video playback position for orientation change 
    savedInstanceState.putInt("Position", myVideoView.getCurrentPosition()); 
    myVideoView.pause(); 
} 

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

}

希望这会有所帮助
