我尝试下载，但显示是这样的：

{
  "errors" : [ {
    "status" : 404,
    "message" : "Could not find resource"
  } ]
}

我的 build.gradle 显示 Gradle 项目同步失败。基本功能将无法正常工作。

对不起我的英语，请帮助我

Answer 1

您可以替换此依赖项

implementation 'com.android.support:appcompat-v7:28.0.3'

有了这个

 implementation 'com.android.support:appcompat-v7:28.0.0'

同时删除这一行

 buildToolsVersion '28.0.3

这对我有用。

Answer 2

您可以在此处查看 appcompat-v7 的最新版本：https://mvnrepository.com/artifact/com.android.support/appcompat-v7?repo=google。
因此，您只能找到 appcompat-v7:28.0.0。

你必须改变 appcompat-v7:28.0.3 到 appcompat-v7:28.0.0。没有别的了。
