Why don't you go about finding the extensions of file manually like this,

Intent intent= new Intent();
        intent.setAction(Intent.ACTION_VIEW);
        Uri filetype= Uri.parse("file://" + file.getPath());
        String filename=file.getName();
if(filename.endsWith(".mp4")||filename.endsWith(".3gp"))
 {
            intent.setDataAndType(filetype, "video/*");
            startActivity(intent);
        }
