【问题描述】：

当我尝试在 Android Studio 中连接 Firebase 时，我得到一个空异常。首先，“工具”选项卡下没有“Firebase”选项，所以我必须在 Android Studio 中搜索它。当它从搜索中出现并单击“Firebase”时，我收到一条错误消息：

Exception in plugin Firebase Services. Moments ago. Occurred once since the last clear. Unread.

在随之出现的小弹出框中有这个 Java 异常：

我在这里做错了什么？我之前从未在这台 Macbook Pro 上将 Firebase 连接到 Android Studio。

【解决方案1】：

我在 Windows 系统中遇到了同样的问题。这对我有用：

尝试取消选中文件>设置>插件下的所有firebase插件

点击确定，会重启IDE。

之后重复相同的过程，再次检查并安装 firebase 插件。您的 IDE 将重新启动。
