在應用程式的主頁面，想取得 Expo push token 時，出現以下訊息：

Error: Call to function ExpoPushTokenManager.getDevicePushTokenAsync has been rejected
Caused by: java.lang.lllegalStateException: Default FirebaseApp is not initialized in thes process com.jim.notification. Make sure to call FirebaseApp.initializeApp(context) first.

使用 npx expo prebuild --platform android --clean 來進行預備構建。

> npx expo prebuild --platform android --clean

資料來源：stakeoverflow - React Native Expo Push Notification ExpoPushTokenManager.getDevicePushTokenAsync has been rejected

重新執行 npx expo run:android，在 Expo push token 有相同的異常訊息。

原來，雖然我們引進了 React Expo Notification library，Android 裝置上的推播邏輯仍需在 Android 原生平台依賴 Google FCM 來實現。
