java - Read mp3 tags in android application -

-

i use jid3lib java. when i'm working library on file stored in computer works great, when try read mp3 tags of files on emulator's sdcard got exeption.

i use following code:

protected void oncreate(bundle savedinstancestate) {     super.oncreate(savedinstancestate);     setcontentview(r.layout.main_activity);      file musicpath = environment.getexternalstoragepublicdirectory(environment.directory_music);      file[] songs = musicpath.listfiles();      (int i=0; < songs.length; i++){         try {             mp3file song = new mp3file(new file(songs[i].getpath()));             log.d("test", song.getid3v1tag().getalbum() );          } catch (tagexception e) {             log.d("test", "tag exception");             e.printstacktrace();         } catch (exception e) {             log.d("test", "exception");                          e.printstacktrace();         }      } }

i put 2 mp3 files in sdcard, still got exception in log. can problem here?

i got following error @ logcat:

java.io.filenotfoundexception: /mnt/sdcard/music/song.mp3: open failed: eacces (permission denied)

but when i'm looking in file explorer of ddms can see files under path, , if use loop in order print file's names show correct names.

eacces (permission denied)

add read_external_storage permission in manifest file.

and, maybe write_external_storage also.
