How to open a specific folder using Android using Intent

My app records videos in the Pictures / MyCamera folder. Is there any way to open, the default Android gallery, only in that folder?
I used this code and it did not work.

Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
Uri uri = Uri.parse(Environment.getExternalStorageDirectory().getPath()
                + "/Pictures/MyCameraApp/");
intent.setDataAndType(uri, "mp4/*");
startActivity(intent);

Hello @ tiago-amaral, how are you? I want to access the folder where my app records, the videos made by the camera. Which is in Pictures / MyAppCamera. In case I wanted to open an intent, for the user to be able to select the video understood? When I put the " / ", it shows all videos, from the other folder. What I want it to show only from my specific folder.
