Я пытаюсь использовать библиотеку StandOutWindow, в которой я пытался создать MusicPlayer из этого Это руководство Мой ListView показывает песни, но когда я нажимаю на песни, происходит сбой приложения. Что мне не хватает? Спасибо.

getSonglist();
Collections.sort(songList, new Comparator<Song>() {
public int compare(Song a, Song b) {
return a.getTitle().compareTo(b.getTitle());
}
});
SongAdapter songAdapter = new SongAdapter(this, songList);
songView.setAdapter(songAdapter);
songView.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
musicService.playSong();
}

Вам нужно добавить публичный метод songPicked() в свою активность.
