我已经在线检查过，但没有任何效果。我被卡住了 4 天，请检查我的 App 和 Project gradle 文件并告诉我。请帮助我。提前致谢。

【问题讨论】：

能否请您发布您的项目级别的 build.gradle 文件？
嗨 Priyankagb，添加了项目构建 gradle 文件。请检查并帮助我。
可能存在版本问题，请更新所有依赖和gradle版本和google服务版本
是的，它正在从浏览器下载 .pom 文件
每次构建项目时都会出现

标签： android android-studio build.gradle

【解决方案1】：

据我所知，您在标题中提到的 Android Studio 版本已更新为 3.5.3 并且您正在使用 3.3.2 Build Gradle 版本。我认为 Gradle 版本正在创建一个问题尝试将您的 Gradle 版本更新为 3.5.0、3.5.1 或 3.5.2 [Gradle 版本]

在您的项目中构建 Gradle

dependencies {
        classpath 'com.android.tools.build:gradle:3.5.2'

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
        classpath 'com.google.gms:google-services:3.0.0'
    }

【讨论】：

您好 Vinesh，我已尝试将构建工具版本更新到 3.5.0，但每次构建项目时仍然存在异常。
您的 Android Studio 版本是 3.5.3 尝试将您的 gradle 更新到 3.5.2 或 3.5.3
我已经检查了 3.5.2、3.5.3。没有运气，还是一样

【解决方案2】：

请尝试在服务器证书中添加证书（首选项 -> 工具 -> 服务器证书 -> 单击 + 按钮 并在那里添加.cer 文件。

要获取.cer，请转到 pom library URL 并单击 URL 左侧的 lock 或 developer settings --> security 并将证书下载为 .cer 并上传到 android studio。
