Java 获取视频捕获的默认MediaStore文件扩展名

我有一个从MediaStore拍摄的视频

           String videoFileName = String.valueOf(java.util.UUID.randomUUID());
           String fileExtension = "." + "mp4";
           String root = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DCIM).getAbsolutePath();

           String videoFilePath = root + File.separator + videoFileName + fileExtension;

           File videoFile = new File(videoFilePath);

           String myCurrentVideoPath = videoFile.getAbsolutePath();

           Intent takeVideoIntent = new Intent(MediaStore.ACTION_VIDEO_CAPTURE);
           if (takeVideoIntent.resolveActivity(getActivity().getPackageManager()) != null) {
               if (videoFile != null) {
                   takeVideoIntent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(videoFile));
                   startActivityForResult(takeVideoIntent, REQUEST_VIDEO_CAPTURE);
               }
           }
           ...

这是通过

onClick

方法完成的是否可以为MediaStore使用defaut视频文件扩展名，并将其指定为my

String fileExtension=“.”+“mp4”。我想这样做，因为有些cheep设备只录制
.3gp
