Android file chooser redirects audio files to /external -

-

i writing app requires user choose files of various types on phone. use code launch file chooser intent:

 intent intent = new intent(intent.action_get_content);  intent.settype("file/*");  startactivityforresult(intent.createchooser(intent, "unhelpful text"), integer_constant);

and here relevant part of onactivityresult:

if (requestcode == integer_constant && resultcode == result_ok) {         uri uri = data.getdata();         path = uri.getpath();         log.i(debug_tag, "path: " + path); }

when choose pdf file or video on sd card, path displayed log should be: /storage/emulated/path/to/file. when choose audio file in wav format in same folder document or video (or other folder), path printed log /external/audio/media/217.

why happen, , how can retrieve actual path of file?
