The Mime type is a description of the content you're looking for. For example, a JPEG image will have a "image/jpeg" type. As for TTF files, although there is no officially registered MIME type, the most commonly used (according to Wikipedia) is
application/x-font-ttf
The documentation on Intents give an example using an ACTION_GET_CONTENT action. here's how you could use it :
Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
intent.setType("application/x-font-ttf");
startActivityForResult(intent,PICKFILE_RESULT_CODE);
