Unified management of Android version

Preface

Because the projects are now more modular and componentized, there are more models to be used, and a model has a build.gradle file, which contains compileSdkVersion or buildToolsVersion. Inconsistent versions may cause compilation errors, so make a version Unified management

Create a new project with a .gradle file

What I created here is versions.gradle

Then write your corresponding version number in it

Instructions

Initialize in your root directory build.gradle.

This name must be the name you created

At last

Write in the build.gradle of the subdirectory.

Here is the usage of the dependency. The

above is my own set of solutions. I hope you can support me
