为什么我来自ContentValues的Newuri是无效的?以编程方式设置铃声

Question

我试图将歌曲设置为铃声。我找到了很多方法来做到这一点，但没有任何效果。这些方式之一如下：

 private void setSongAsRingtone(Song song){
        File ringFile = new File(song.getPath());
        Log.d(tag, "Ring name: " + ringFile.getName());
        Log.d(tag, "Ring absolute path: " + ringFile.getAbsolutePath());
        Log.d(tag, "Activity: " + getActivity().toString());
        ContentValues values = new ContentValues();
        values.put(MediaStore.MediaColumns.DATA, ringFile.getAbsolutePath());
        values.put(MediaStore.MediaColumns.TITLE, song.getTitle());
        values.put(MediaStore.MediaColumns.MIME_TYPE, "audio/*");
        values.put(MediaStore.MediaColumns.SIZE, 26454);
        values.put(MediaStore.Audio.Media.ARTIST, song.getArtist());
        values.put(MediaStore.Audio.Media.IS_RINGTONE, true);
        values.put(MediaStore.Audio.Media.IS_NOTIFICATION, true);
        values.put(MediaStore.Audio.Media.IS_ALARM, true);
        values.put(MediaStore.Audio.Media.IS_MUSIC, false);
        Uri uri = MediaStore.Audio.Media.getContentUriForPath(ringFile.getAbsolutePath());
        Uri newUri = getActivity().getContentResolver().insert(uri, values);
        RingtoneManager.setActualDefaultRingtoneUri(getActivity(), RingtoneManager.TYPE_RINGTONE, newUri);
    }

logcat说：

D/RingtoneDialogFragment: Ring name: Jamal - Peron [Official Music Video].m4a
D/RingtoneDialogFragment: Ring absolute path: /storage/emulated/0/storage/emulated/0/Download/Jamal - Peron [Official Music Video].m4a

I/RingtoneManager: ringtone title : Jamal - Peron [Official Music Video], DRM : 0

但是 newuri对象为null ，我有一些错误。也许有人知道为什么？

事先感谢您的帮助。晚上愉快。

我在插入（创建newuri）之前必须调用此方法：

String filePathToDelete = MediaStore.MediaColumns.DATA + "="" + ringtoneFile.getAbsolutePath() + """;
getActivity().getContentResolver().delete(uri, filePathToDelete, null);
