Android后台BroadcastReceiver监听PROXY_CHANGE触发异常求助

我需要监听网络代理的变化，在变化发生时检测网络状态，已在onReceive方法中加入日志打印。目前遇到的现象：

• 应用处于Activity前台时，日志能正常输出；
• 进入设置界面配置代理（应用后台）时，onReceive的日志不会触发，返回Activity后会立即触发；
• 后续确认实际情况：后台切换网络时onReceive会触发一次，之后再切换网络就不再触发了。

已尝试使用WakeLock但没有效果，期望后台能正常执行onReceive中的代码，麻烦帮忙排查代码问题，提前感谢！

NetworkReceiver 代码 #

public class NetworkReceiver extends BroadcastReceiver {
    @Override
    public void onReceive(Context context, Intent intent) {
        Log.d("NetworkChange", "onReceiveTest 代理接收器接收到了: " + intent.getAction());

        InternetConnectionStatusHelper internetConnectionStatusHelper = InternetConnectionStatusHelper.getInstance(context);
        ConnectivityManager connectivityManager = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);
        ProxyInfo proxyInfo = connectivityManager.getDefaultProxy();
        if (proxyInfo != null) {
            String host = proxyInfo.getHost();
            int port = proxyInfo.getPort();
            Proxy proxy = new Proxy(Proxy.Type.HTTP, new InetSocketAddress(host, port));
            internetConnectionStatusHelper.setmProxy(proxyInfo);
            internetConnectionStatusHelper.checkConnection();
            Log.d("NetworkChange", "onReceive has: 代理");
        } else {
            internetConnectionStatusHelper.checkConnection();
            Log.d("NetworkChange", "onReceive: 无代理");
        }
    }

}

NetworkService 代码（接收器注册逻辑） #

public class NetworkService extends Service {
    private final String TAG = "NetworkChange";
    BroadcastReceiver networkReceiver;
    @Override
    public void onCreate() {
        IntentFilter intentFilter = new IntentFilter();
        intentFilter.addAction("android.intent.action.PROXY_CHANGE");
        networkReceiver = new NetworkReceiver();
        registerReceiver(networkReceiver, intentFilter);
        Log.d(TAG, "服务创建了");
      
        super.onCreate();
    }
}
