因此，我开始了一个新的Ionic项目，该项目使用Google Plus plugin和Firebase Cloud Messaging for push notifications。将这些添加到我的项目后，我将无法成功构建apk。这是我收到的消息：

谷歌搜索此问题导致我to this Github issue。建议的“解决方案”对我不起作用。通过修改platforms目录下的文件，最终使项目得以构建，但通知无法正常工作。即使其中一种解决方案确实对我有用，但它们似乎都不安全。将依赖项的依赖项安装到项目中之后，修改它们的依赖项有些不对劲。
有没有人找到将Googe登录和推送通知添加到Ionic应用程序的好解决方案？此时，如果无法解决，我准备用其他方式重写它。这两个功能对于我的应用程序都是必不可少的。没有通知，它将毫无用处。而且我讨厌不得不编写自己的身份验证模块，因为我无法让这些插件协同工作。
任何帮助将不胜感激。
