世博会推送令牌没有在android独立应用程序中创建。

Question

我试着解决这个问题很长时间了，但没有什么效果，ExpopushToken不是在安卓独立应用程序中创建的，而它在ios中运行时是预期的。我按照文档的字面意思，用无限制的google云平台键创建了所需的所有东西，键不是自动创建的，我创建了一个令牌，在那里我应该将用户数据保存为android中的空字符串。

代码完全取自文档，google-services文件就像主根目录中提到的那样被添加，并上传到服务器上。

const registerForPushNotificationsAsync = async () => {
    let token;
    if (Constants.isDevice) {
      const { status: existingStatus } =
        await Notifications.getPermissionsAsync();
      let finalStatus = existingStatus;
      if (existingStatus !== "granted") {
        const { status } = await Notifications.requestPermissionsAsync();
        finalStatus = status;
      }
      if (finalStatus !== "granted") {
        alert("Failed to get push token for push notification!");
        return;
      }
      token = (await Notifications.getExpoPushTokenAsync()).data;
    } else {
      alert("Must use physical device for Push Notifications");
    }

    if (Platform.OS === "android") {
      Notifications.setNotificationChannelAsync("default", {
        name: "default",
        importance: Notifications.AndroidImportance.MAX,
        vibrationPattern: [0, 250, 250, 250],
        lightColor: "#FF231F7C",
      });
    }

    return token;
  };

  useEffect(() => {
    registerForPushNotificationsAsync().then((token) =>
      setExpoPushToken(token)
    );

    notificationListener.current =
      Notifications.addNotificationReceivedListener((notification) => {
        setNotification(notification);
      });

    responseListener.current =
      Notifications.addNotificationResponseReceivedListener((response) => {
        console.log(response, "response");
      });


    return () => {
      Notifications.removeNotificationSubscription(
        notificationListener.current
      );
      Notifications.removeNotificationSubscription(responseListener.current);
    };
  }, []);

在app.json中

"plugins": [
  [
    "expo-notifications",
    {
      "icon": "./assets/mainLogo.png",
      "color": "#ffffff",
      "sounds": [
        "./assets/notificationsound.wav",
        "./assets/notificationsoundothers.wav"
      ]
    }
  ],
  ["expo-image-picker"],
  ["expo-camera"]
],
"updates": {
  "fallbackToCacheTimeout": 0
},
"assetBundlePatterns": ["**/*"],
"notification": {
  "icon": "./assets/logo2.png",
  "color": "#e8e8e8",
  "iosDisplayInForeground": true,
  "androidMode": "collapse",
  "androidCollapsedTitle": "New Notification"
},

我想出了世博文档中可能传递给谁的问题。有人提到，您必须检查使用google-services.json文件下载的api密钥，并确保它是您的.它将不是您的，如果您更改为您的api密钥，它将无法工作。把它下载下来，它就能工作了

我在没有结果的情况下花了5天时间搜索后发现了这一点
