java - Firebase 连接不可用 Android Studio 3.2

Question

当我尝试在 Android Studio 中连接 Firebase 时，出现 null 异常。首先，“工具”选项卡下没有“Firebase”选项，因此我必须在 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.

在随之而来的小弹出框中出现了这个 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。

Answer 1

我在Windows系统中也遇到了同样的问题。这对我有用:

尝试取消选中"file">“设置”>“插件”下的“所有 firebase 插件”

单击“确定”，它将重新启动 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。
