Because Android studio and Android related SDKs and build tools have extremely fast update speeds.Modifications to relevant versions are sometimes more sensitive, especially in team projects where individuals modify the version of the relevant tool locally and accidentally submit it to a remote code repository. Others often have problems updating.The version field in the Android studio project file is very scattered. When the SDK environment changes, it is still more troublesome to modify.This article uses configuration files to centrally control build tool versions.
The gradle.properties file defines version information and assigns values in the project root directory
