Ionic Android RuntimeException FirebaseInitProvider IllegalArgumentException: Given String is empty or null

Question

使用 Ionic 构建项目。在 Android SDK 中生成 Android 构建和导入之后。

在设备/模拟器中运行应用程序时出错。还使用 FCM 进行推送通知。

安装 APK 后出现 Android 运行时错误：

我的配置有问题还是在处理 Android 构建时缺少某些东西？

我也有同样的问题，现在解决了。 在我的情况下，空值或 null 值是 google-services.json 中的“current_key”值，所以我填写 Firebase 控制台中的值（Web API 密钥）
