Android LocalBroadcastManager中的NullPointerException

我试图在短信到达后更新我的列表。我得到了正确的接收器，但当我试图将接收器发送到我的班级时，我在一些电话中得到了以下错误

我的代码在某些手机中正常工作

我已使用以下代码发送广播：

Intent intent = new Intent(filtering);
intent.putExtra(RESULT, result);
LocalBroadcastManager.getInstance(this).sendBroadcast(intent);

receiver = new BroadcastReceiver() {

            @Override
            public void onReceive(Context context, Intent intent) {

                Bundle bundle = intent.getExtras();

                if (bundle != null) {
                    int resultCode = bundle
                            .getInt(NormalIncommingTextService.RESULT);

                    if (resultCode == Activity.RESULT_OK) {
                        RefreshList(getActivity());

                    }
                }

            }
        };

我用下面的代码得到接收器：

Intent intent = new Intent(filtering);
intent.putExtra(RESULT, result);
LocalBroadcastManager.getInstance(this).sendBroadcast(intent);

receiver = new BroadcastReceiver() {

            @Override
            public void onReceive(Context context, Intent intent) {

                Bundle bundle = intent.getExtras();

                if (bundle != null) {
                    int resultCode = bundle
                            .getInt(NormalIncommingTextService.RESULT);

                    if (resultCode == Activity.RESULT_OK) {
                        RefreshList(getActivity());

                    }
                }

            }
        };

我已使用以下代码在onResume和onPause中注册和注销我的收件人：

LocalBroadcastManager.getInstance(this).registerReceiver(Home.receiver,
                new IntentFilter(NormalIncommingTextService.NOTIFICATION));
// registerReceiver

LocalBroadcastManager.getInstance(this).unregisterReceiver(Home.receiver); // unregisterReceiver

我搜索了很多，但找不到有效的解决方案

提前感谢您抽出时间

如果你想看到我代码的任何部分，请问我

normalincommmingtextservice.NOTIFICATION

与我的代码中的

过滤功能相同

//编辑

这是第297行@
LocalBroadcastManager

br.receivers.get(j).receiver.onReceive(mAppContext, br.intent);

更多信息，但我不知道有什么问题。这个错误发生在
FragmentActivity
类上，当更新一个片段数据时，我在Activity上测试了它，效果很好

PS：在某些手机中，我在更新
FragmentActivity

//回答

我已经解决了这个问题，使用普通的
BroadCastReceiver
而不是
LocalBroadcastManager

br.receivers.get(j).receiver.onReceive(mAppContext, br.intent);
