motorola 2.3.3中的SD卡无法播放视频

Question

我正在开发一个应用程序，我需要从SD卡播放视频。我正在使用以下代码，它在除摩托罗拉2.3.3设备之外的所有设备上都工作正常。

有时它会播放10-15秒的视频，然后出现黑屏，但有时它只显示黑屏，并在视频视图的底部显示持续时间。

所以，请指引我..谢谢你

VideoView vv = (VideoView) this.findViewById(R.id.video_view);
String filepath = "mnt/sdcard/my_video.mp4";
MediaController mc = new MediaController(this);
mc.setAnchorView(vv);
vv.setMediaController(mc);
vv.requestFocus();
vv.start();

Answer 1

if(play the same video using default player in gallery){

      //you are doing something wrong in ur code    

}else{

//this device has no capabilities to play the provided video with the default codes.
//try to look for any installed app that can play the video for this devices

}
