Android 如何将音频文件传递到广播接收器并将其作为警报播放

我有一个闹钟应用程序，我有一个文本视图，当我按下它时，它会将我重定向到音频文件夹，然后我可以选择一首歌曲并将其作为闹钟播放。当我选择它，然后点击我的设置报警按钮，它会崩溃多少秒后。错误指向广播接收器

这是我的设置报警活动：

@Override
    public void onItemClick(AdapterView<?> parent, View view, int position, long id) {

        Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
        Uri uri = Uri.parse(Environment.getExternalStorageDirectory().getPath()
                + "/Audio/");
        intent.setDataAndType(uri, "audio/*");
        startActivityForResult(intent, 1);

    }

    @Override
    protected void onActivityResult(int requestCode,int resultCode,Intent data){

        if(requestCode == 1){

            if(resultCode == RESULT_OK){

                //the selected audio.
                Uri uri = data.getData();
                Intent n = new Intent(this, AlarmReceiver.class);
                n.putExtra("song", uri.toString());

            }
        }
        super.onActivityResult(requestCode, resultCode, data);
    }
