Java 在播放本地视频时出错

我的文件路径如下

”file:///storage/emulated/0/Android/data/com.testcompany.tesapp/files/recs/1234-7896-9076.mp4“ videoView.setVideoURI（Uri.parse（“file:///storage/emulated/0/Android/data/com.testcompany.tesapp/files/recs/1234-7896-9076.mp4（“”）

播放开始了，但我遇到了这样的错误

11-10 14:12:30.909: E/MediaPlayer(1022): Error (1,-2147483648)

我搜索了这个错误，它说这是未知的MediaPlayer错误，所以如何避免它。

使用此代码从存储器播放视频

Uri vidFile = Uri.parse(
    Environment.getExternalStorageDirectory().getAbsolutePath()+"/download/"+"xyz.mp4");
    VideoView videoView = (VideoView) findViewById(R.id.videoView);
    videoView.setVideoURI(vidFile);
    videoView.setMediaController(new MediaController(MainActivity.this));
    videoView.setVisibility(1);
    videoView.bringToFront();
    videoView.requestFocus();
    videoView.start(); 

}

使用上面的代码并尝试。简单的代码可以播放视频。确保添加了SD卡读写权限

检查viedo是否在这里。您可能正在从android资源播放viedo

package com.AnVideoView;

import android.app.Activity;

 String SrcPath = "/sdcard/Video/Android in Spaaaaaace!_low.mp4";

   /** Called when the activity is first created. */
   @Override

       super.onCreate(savedInstanceState);
       setContentView(R.layout.main);
       VideoView myVideoView = (VideoView)findViewById(R.id.myvideoview);
       myVideoView.setVideoPath(SrcPath);
       myVideoView.setMediaController(new MediaController(this));
       myVideoView.requestFocus();
       myVideoView.start();
   }
