So our app has the option to take either a picture or a video. If the user takes a picture, we can use the MediaStore.Images.Media.insertImage function to add the new image
Try this code. It seems working for me.
filePath = myfile.getAbsolutePath();
ContentValues values = new ContentValues();
values.put(MediaStore.Video.Media.DATA, filePath);
return context.getContentResolver().insert(
MediaStore.Video.Media.EXTERNAL_CONTENT_URI, values);
Example of filePath -
/storage/emulated/0/DCIM/Camera/VID_20140313_114321.mp4
