Access Music files from library programmatically (Android)

Question

I want to access the music library in Android phone (not sdcard) & show it in list. I want to get all info related to each file like duration, artist etc. How would I do that programmatically?

Answer 1

    private void musics(){
    Uri uri = MediaStore.Audio.Media.INTERNAL_CONTENT_URI;
    ContentResolver cr = getContentResolver();
    String[] columns = {MediaStore.Audio.Media.DISPLAY_NAME};//add which column you need here

    Cursor cursor = cr.query(uri, columns, null, null, null);

    if(cursor == null){
        return;
    }
    if(cursor.getCount() > 0){
        cursor.moveToFirst();
        do{
            //read your information here
            String artist = cursor.getString(cursor.getColumnIndex(MediaStore.Audio.Media.DISPLAY_NAME));

        }while(cursor.moveToNext());
    }

    cursor.close();
}
