search json file using intent

Question

What is the correct MIME type for json file(json extnesion) so that only see json files show up when I am browsing the file system through intent?

    Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
    intent.setType("application/json");
    Intent i = Intent.createChooser(intent, "View Default File Manager");
    startActivityForResult(i, 1);

thanks

Surprisingly, Android does NOT support "json" (and "js" for javascript extension) as a MIME type. This is clear, for example, from the source codes of MimeUtils. Also you can use MimeTypeMap helper class and find out that:

MimeTypeMap.getSingleton().getMimeTypeFromExtension("json");

returns null;

The only most close MIME type that can be used instead of "application/json" is "application/octet-stream": it matches "*.json" files among other things, but a lot of other stuff as well. At least it filters out images, texts, music files and videos.
