更新到android studio 2.3后,我收到此错误消息.我知道这只是一个暗示,因为应用程序正常运行,但它真的很奇怪.

所有com.android.support库必须使用完全相同的版本规范(混合版本可能导致运行时崩溃).找到的版本25.1.1,24.0.0.示例包括com.android.support:animated-vector-drawable:25.1.1和com.android.support:mediarouter-v7:24.0.0

我的朋友:

我是一名计算机科学专业的学生,​​我正在尝试熟悉为夏季业余爱好构建应用程序.但是,在过去的几天里,当我尝试同步Gradle时,它给出了同样的错误,说明了这一点

无法下载gradle-core.jar.

我将在这篇文章的底部发布完整的错误消息.

当然,我确保我不在离线模式下工作.最重要的是,我正在使用强制https://获取源http://.我还在文件https://中将distributionUrl 更改为http:// gradle-wrapper.properties.我尝试了不同的代理并更改了build.gradle文件中的存储库jcenter(), mavenCentral(), and google().

我甚至试图与我的防火墙同步并关闭防病毒软件,但没有任何工作.您将在下面找到我的整个错误消息.
