External reference/variable in build.gradle file

Is it possible to use some external reference or variable in build.gradle files?

I have several build.gradle files in my app source files, including the one for module app, module base, module player, etc. (it depends on the structure of your code and the names of your packages).

Inside of each of these files is the following or similar structure:

defaultConfig {
    minSdkVersion 23
    targetSdkVersion 28
    versionCode 1
    versionName "1.0.001"
}

Is there any way I can code this the way that I don't have to change these values in every file? Is it possible to use some external reference or variable and that way I can edit my versionCode, versionName, etc. just on one place?

Yes it is.

In your project-level Gradle config (the one in the root of your project, outside any module folders), you can define variables under the buildscript block:

ext.thisVersionCode = 1
ext.thisVersionName = "1.0.001"

Then you should be able to reference them from your module-level configs:

defaultConfig {
    versionCode = rootProject.ext.thisVersionCode
    versionName = rootProject.ext.thisVersionName
}

In your Project gradle

ext {

    minSdkVersion = 14
    targetSdkVersion = 26
    compileSdkVersion = 26
    buildToolsVersion = '26.0.2'

    // App dependencies
    supportLibraryVersion = '26.1.0'
    mockitoVersion = '1.10.19'
    roomVersion = "1.0.0"
}

In your App gradle

    android {        
            compileSdkVersion rootProject.ext.compileSdkVersion
            buildToolsVersion rootProject.ext.buildToolsVersion

        defaultConfig {

        minSdkVersion rootProject.ext.minSdkVersion
        targetSdkVersion rootProject.ext.targetSdkVersion
       .
       .

    }

        }

        dependencies {
            // App's dependencies, including test
            compile "com.android.support:appcompat-v7:$rootProject.supportLibraryVersion"

        }

Go to File/Project structure/app/flavors then you can get versionCode, versionName, etc then change them what you want and it effects all of your Files.

You can define variables in top level build.gradle file and then reference these variables in each module's build.gradle - that way youll be changing them only once in one file.

to give you an example,this is top level file https://github.com/Ejstn/android-starter/blob/master/build.gradle and this one is module level file: https://github.com/Ejstn/android-starter/blob/master/app/build.gradle

You can also declare whole dependency as variable like in this google's app: https://github.com/google/santa-tracker-android/blob/master/build.gradle
