Firebase助手無法啟動（撲動）

Question

我似乎無法讓Firebase Assistant在Android Studio中工作，並出現以下錯誤。

我已經安裝了所有必需的插件和SDK工具，包括：
Google Repository Firebase App Indexing Firebase Services Firebase Testing

我的配置如下。

當我嘗試將任何Firebase集成到應用程序中時，我會遇到一系列編譯錯誤，這些錯誤會在刪除該代碼時消失。 我懷疑我配置錯誤或某處存在版本沖突。

我正在運行Android Studio 3.1

Answer 1

我有同樣的問題。 我轉到“設置”>“插件”，然后刪除了所有3個firebase插件。 重新啟動。 返回插件，添加所有3個firebase插件。 重新開始。 然后工作正常！

Answer 2

我也遇到了這個問題，並通過更新所有內容解決了它：

• Android Studio 3.1-> 3.2
• 我已經安裝的所有SDK工具（工具> SDK管理器> SDK工具）
• Flutter和Dart插件（“首選項”>“插件”）

我還嘗試了Justin的答案，即卸載Firebase插件，然后重新啟動，然后重新安裝。

完成所有操作后，重新啟動Android Studio，並讓IDE完成其所有索引編制和其他任務，然后打開Firebase助手（“工具”>“ Firebase”）
