我在我的Android应用程序中调用视频播放器，意图播放视频。播放视频时不会发生错误。关闭视频播放器应用程序后，我的应用程序停止。 我用这个方法：
private void play_video() {
Intent intent = new Intent();
intent.setAction(android.content.Intent.ACTION_VIEW);
File file = new File(Environment.getExternalStorageDirectory().getPath() + "/nabege" + File.separator + "video"
+ File.separator + videoFileName);
intent.setDataAndType(Uri.fromFile(file), "video/*");
startActivity(intent);}
