我刚刚安装了新版本的 Android Studio 并尝试使用内置模板创建项目。

我的环境是: Windows 7，SP1，64 位 在安全的域环境中，我是我机器上的域管理员。

这是我看到的:

Answer 1

问题出在您的 gradle/wrapper/gradle_wrapper.properties 文件中。我不确定它是怎么发生的，但是你有一个不正确的 URL 用于 Gradle 的可下载分发。从此更改该行:

distributionUrl=file://C:/Users/stuz/.gradle/wrapper/dists/gradle-1.10-all.zip

为此:

distributionUrl=http\://services.gradle.org/distributions/gradle-1.10-all.zip
