我似乎无法让Firebase助手在Android Studio中运行并出现以下错误。

我已经安装了所需的所有插件和SDK工具，包括：
Google Repository Firebase App Indexing Firebase Services Firebase Testing

我的配置如下。

的build.gradle

buildscript {
    ext.kotlin_version = '1.2.31'
    repositories {
        google()

    delete rootProject.buildDir
}

应用/的build.gradle

    localPropertiesFile.withReader('UTF-8') { reader ->
        localProperties.load(reader)
    }
}

def flutterRoot = localProperties.getProperty('flutter.sdk')
if (flutterRoot == null) {
    throw new GradleException("Flutter SDK not found. Define location with flutter.sdk in the local.properties file.")

当我尝试在应用程序中集成任何firebase时，我得到一系列编译错误，当我删除该代码时，这些错误就会消失。我怀疑我有一些配置错误或某处存在版本冲突。

我正在运行Android Studio 3.1

Answer 1

我遇到了同样的问题。我去了设置＆gt;插件然后删除所有3个firebase插件。重新启动。回到插件，添加所有3个firebase插件。重新开始。然后它工作正常！

Answer 2

我也遇到了这个问题，并通过更新所有内容解决了该问题：

Android Studio 3.1-> 3.2
我已经安装的所有SDK工具（工具> SDK管理器> SDK工具）
Flutter和Dart插件（首选项>插件）

我还尝试了Justin的答案，即卸载Firebase插件，然后重新启动，然后重新安装。

完成所有操作后，重新启动Android Studio，并让IDE完成其所有索引编制和其他任务，然后打开Firebase助手（“工具”>“ Firebase”）

Firebase助手无法启动（颤动）
