Question

我正在经历article，它对update your project's compileSdkVersion and targetSdkVersion to API 28说。所以我做了，但是支持库给出了错误，例如支持库不应使用与compileSdk版本不同的版本

我尝试将其更新为28.0.0，但无法正常工作并说

Failed to resolve: com.android.support:appcompat-v7:28.0.0

我知道它仍然可以与27.1.1一起使用，但是使用什么正确的版本却不会出现红色下划线？

build.gradle文件

apply plugin: 'com.android.application'

我知道已经回答了这个问题，但是我今天也需要更新我的回答，上面答案中的任何一个链接都没有真正告诉我要输入的内容。所以我必须使用以下内容：

*   Trying ::1...
* TCP_NODELAY set
* Connected to localhost (::1) port 8081 (#0)
> GET / HTTP/1.1
> Host: localhost:8081
> User-Agent: curl/7.54.0
> Accept: */*

< Connection: keep-alive

* Connection #0 to host localhost left intact

我希望这可以帮助其他人寻找放置在那里的东西。
