对不起我的英语，请帮助我
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'
并删除此行
buildToolsVersion '28.0.3
这对我来说是工作.
您可以在那里查看最新版本的appcompat-v7：https://mvnrepository.com/artifact/com.android.support/appcompat-v7?repo=google。
所以，你可以找到appcompat-v7:28.0.0.
你必须改变appcompat-v7:28.0.3appcompat-v7:28.0.0.没有别的了。
