Android 如何从非React类发送React应用程序上下文？

我需要更新状态更改，比如android和react本机类之间的事件

public class MessagingService extends FirebaseMessagingService {
      @Override
      public void onMessageReceived(RemoteMessage remoteMessage) {
        Log.d(TAG, "Push Message Received ");
        buildLocalNotification(remoteMessage);
      }

      public void buildLocalNotification(RemoteMessage message) {
        ...
        FBMessagingHelper notificationHelper = new FBMessagingHelper(this.getApplication());
        notificationHelper.showNotification(bundle);
      }
    }

当类扩展到FBMessingService时，如何创建

ReactApplicationContext

构造函数

FBMessagingHelper notificationHelper = new FBMessagingHelper(this.getApplication());
// Getting Error as a parameter is not react app context

我需要更新视频进度中的

状态

通过
React Native
启动/停止视频时，更新到
Android
通过
Android
启动/停止视频时，更新到
React Native
创建的本机模块：

    public class FBMessagingPackage implements ReactPackage{
    @Override
      public List<NativeModule> createNativeModules(ReactApplicationContext reactContext) {
        List<NativeModule> modules = new ArrayList<>();
        modules.add(new FBMessagingHelper(reactContext));
        modules.add((NativeModule) new MessagingService(reactContext));
        // Error: cannot be cast to nativeModule
        return modules;
      }
        ...
        ...
    }

公共类FBMessagingPackage实现了ReactPackage{
@凌驾
公共列表createNativeModules（ReactApplicationContext reactContext）{
列表模块=新的ArrayList（）；
添加（新的FBMessagingHelper（reactContext））；
modules.add（（NativeModule）new MessagingService（reactContext））；
//错误：无法转换为nativeModule
返回模块；
}
...
...
}
我不知怎么解决了这个问题。我们无法在
FirebaseMessagingService
上扩展
ReactApplicationContext
。即使应用程序未运行且我们无法控制添加react上下文，也会调用此服务

因此，我创建了一个单独的模块并添加了监听器，这些监听器将更新事件数据到FBMessagingHelper类

public class FBMessagingPackage implements ReactPackage{
    @Override
      public List<NativeModule> createNativeModules(ReactApplicationContext reactContext) {
        List<NativeModule> modules = new ArrayList<>();
        modules.add(new VideoModule(reactContext));
        return modules;
      }
    }

public class FBMessagingPackage implements ReactPackage{
    @Override
      public List<NativeModule> createNativeModules(ReactApplicationContext reactContext) {
        List<NativeModule> modules = new ArrayList<>();
        modules.add(new VideoModule(reactContext));
        return modules;
      }
    }

public class VideoModule extends ReactContextBaseJavaModule {
   private ReactApplicationContext mContext;

  public VideoModule(ReactApplicationContext reactContext) { // Added into Native Modules
     mContext = applicationContext;
  }

@ReactMethod
    public void onVideoProgress(Bolean status){
        FBMessagingHelper.IN_VIDEO_PROGRESS = status 
        // Store it to public static variable of FBMessagingHelper
    }

 @Nonnull
 @Override
    public String getName() {
        return "VideoModule";
    }


}
