messaging().onNotificationOpenedApp 从未被触发，messaging().getInitialNotification() 被触发但 remoteMessage 始终为 null

Question

我正在使用 react-native-firebase v6.4.0。我用 setBackgroundMessageHandler 成功注册了后台处理程序，一切正常。现在，当应用程序处于 background/quit 并且我正在使用 onNotificationOpenedApp/getInitialNotification 时，我正在尝试处理通知点击。我面临的问题是第一个方法永远不会被触发而第二个被触发但 remoteMessage 参数总是 null。我也试过生成一个发布版本，但结果是一样的。

index.js

// imports

messaging().setBackgroundMessageHandler(async remoteMessage => {
  // storing the message with redux
});

function HeadlessCheck({isHeadless}) {
  return isHeadless ? null : <App />;
}

AppRegistry.registerComponent(appName, () => HeadlessCheck);

App.js

// other imports
import messaging from '@react-native-firebase/messaging';
import {store, persistor} from './Store';

export default function App() {
  useEffect(() => {
    (async () => await messaging().registerDeviceForRemoteMessages())();

    const unsubscribe = messaging().onMessage(async remoteMessage => {
      store.dispatch(storeNews(remoteMessage));
    });

    messaging().onNotificationOpenedApp(remoteMessage => {
      // The below code gets never executed
      Alert.alert('here');
      console.log(
        'Notification caused app to open from background state:',
        remoteMessage,
      );
    });

    messaging()
      .getInitialNotification()
      .then(remoteMessage => {
        console.log(remoteMessage); // always prints null
        if (remoteMessage) {
          // Never reached
          Alert.alert('here');
          console.log(
            'Notification caused app to open from quit state:',
            remoteMessage,
          );
        }
      });

    return unsubscribe;
  }, []);

  return (
    <>
      <StatusBar barStyle="dark-content" />
      <Provider store={store}>
        <PersistGate loading={null} persistor={persistor}>
          <RootNavigator />
        </PersistGate>
      </Provider>
    </>
  );
}

感谢任何帮助。非常感谢。

我找到了导致我的问题的原因。我在我的应用程序中有一个本地启动画面的配置，使用 react-native-splash-screen 包所必需的实现。

我添加了一个名为 SplashActivity.java 的新闻文件：

public class SplashActivity extends AppCompatActivity {
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        try {
            super.onCreate(savedInstanceState);
            Intent intent = new Intent(this, MainActivity.class);
            startActivity(intent);
            finish();
       }
        catch(Exception e) {
           System.out.println(e.getMessage());
       }

我想要 SplashActivity 我的主要 Activity，在 AndroidManifest.xml：

       <activity
          android:name=".SplashActivity"
          android:theme="@style/SplashTheme"
          android:label="@string/app_name">
          <intent-filter>
              <action android:name="android.intent.action.MAIN" />
              <category android:name="android.intent.category.LAUNCHER" />
          </intent-filter>
        </activity>

      <activity
        android:name=".MainActivity"
        android:label="@string/app_name"
        android:configChanges="keyboard|keyboardHidden|orientation|screenSize"
        android:windowSoftInputMode="adjustResize"
        android:exported="true" />

然后更改我的 MainActivity.java 上的一些逻辑，看起来像：

import android.os.Bundle;
import org.devio.rn.splashscreen.SplashScreen;
public class MainActivity extends ReactActivity {
 @Override
    protected void onCreate(Bundle savedInstanceState) {
        SplashScreen.show(this);
        super.onCreate(savedInstanceState);
    }
}

因此事件未正确传递，有关更多信息，请参阅此 react-native-firebase 存储库的评论 issue

关于 this comment

My solution to this problem is pretty implementation specific, but you never know what might help.

My issue was that I had a splash activity which was the actual launcher activity. To get the callbacks to fire in App.js I had to: Add "singleTop" to the activity tag for SplashActivity.java in AndroidManifest.xml Use "this.getIntent();" within the onCreate method of SplashActivity.java to intercept the intent from the firebase notification open event Use .getExtras() to take the bundle from the intercepted intent and attach it to a new intent forwarded to .MainActivity As soon as .MainActivity had access to the intent all of the callbacks began firing on the correct events.

实施以解决 this comment

所以我在 may Splash 上添加了这个逻辑Activity:

        Bundle extras = getIntent().getExtras();
        if (extras != null) {
            intent.putExtras(extras);
        }

现在看起来像：

public class SplashActivity extends AppCompatActivity {
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        try {
  //  Block of code to try
        super.onCreate(savedInstanceState);

        Intent intent = new Intent(this, MainActivity.class);

        // Pass along FCM messages/notifications etc.
        Bundle extras = getIntent().getExtras();
        if (extras != null) {
            intent.putExtras(extras);
        }
        startActivity(intent);
        finish();
}
catch(Exception e) {
  //  Block of code to handle errors
  System.out.println(e.getMessage());
}
    }
}

现在我可以获得 getInitialNotification() return 和 onNotificationOpenedApp() 事件。在 Android 上，如果应用程序处于后台或退出状态，则始终调用 getInitialNotification()，这可能是因为我的启动画面逻辑。但对我来说现在还可以，我会在两者上做完全相同的事情

messaging().onNotificationOpenedApp 从未被触发，messaging().getInitialNotification() 被触发但 remoteMessage 始终为 null

messaging().onNotificationOpenedApp is never triggered, messaging().getInitialNotification() is triggered but remoteMessage is always null
