Gradle Mixing Assemblies

Question

Is there a way to “mix” multiple flavors in gradle?

For example, let's say I have two options: Red and Blue . Now let me say that I have two flavors that I want them to have (sub-flavors if you want): Complex and Simple .

What I know so far is that it will require me to create four flavors: Red-Complex , Red-Simple , Blue-Complex , Blue-Simple .

I do not understand how this should be structured within the project. How to define a Red code that is split between Red-Complex and Red-Simple flavors, but also has a Complex code that is split between Red-Complex and Blue-Complex ? I do not want to copy / paste the code between tastes.

What is the best way to achieve this in gradle?

Here's how flavoring works: https://proandroiddev.com/advanced-android-flavors-part-1-building-white-label-apps-on-android-ade16af23bcf

→ In your src folder you want to create 2 varieties called "red", "blue".

→ Create 2 folders with the name "red", "blue" in src (the same level as the main one).

→ folder structure as the main one.

→ Here you have the option to override any XML / resources / Java files / values, etc.

→ (resources with the same name as main will be redefined when creating Flavor).

→ Use the sample code in build.gradle to add flavor to the project.

 productFlavors { blue{ minSdkVersion 21 applicationId 'something' targetSdkVersion 28 versionCode 1 versionName "1.0.0" } red { minSdkVersion 21 applicationId 'something' targetSdkVersion 28 versionCode 1 versionName '1.0.0' } } buildTypes { Debug { } Release { } } 

Will give assembly options:

 blueDebug blueRelease redDebug redRelease 

// ================ Add additional tastes to it ================

Here: https://proandroiddev.com/advanced-android-flavors-part-2-enter-flavor-dimensions-4ad7f486f6

→ have sub-flavors such as Simple, Complex (in other words "buildTypes").

→ For sub-flavors or, say, buildTypes, we use sizes.

→ flavourDimensions "Flavor", "SubFlavour" (in your build.gradle) // It can be any keyword, use it inside yourself // think of this keyword as a group identifier that defines a collection of options as a group.

→ Use it to your liking → We may think that the Keyword “dimension” is more like defining a set of aroma and sub-aroma

 flavorDimensions "Flavour", "SubFlavour" productFlavors { // group one Simple { dimension "SubFlavour" } Complex { dimension "SubFlavour" } //group two // Take a note: do not use upper case in your flavours (one which match the folder names in src) // Sub-Flavours can have Upper case blue { dimension "Flavour" minSdkVersion 21 applicationId 'something' targetSdkVersion 28 versionCode 1 versionName "1.0.0" } red { dimension "Flavour" minSdkVersion 21 applicationId 'something' targetSdkVersion 28 versionCode 1 versionName '1.0.0' } } 

→ If configured correctly, you will see below buildVariants.

// ================== build.gradle ================= // Your build.gradle may look here.

 android { buildTypes { debug { } release { } // Any other you want to add here // Ex, development {} } flavorDimensions "Flavour", "SubFlavour" productFlavors { Simple { dimension "SubFlavour" } Complex { dimension "SubFlavour" } Blue { dimension "Flavour" minSdkVersion 21 applicationId 'something' targetSdkVersion 28 versionCode 1 versionName "1.0.0" } Red { dimension "Flavour" minSdkVersion 21 applicationId 'something' targetSdkVersion 28 versionCode 1 versionName '1.0.0' } } sourceSets { main { aidl.srcDirs = ['src/main/aidl', 'src/main/res/animation', 'src/main/res/animations'] res.srcDirs = [ 'src/main/res/anim', 'src/main/res/layouts/xyz', 'src/main/res/layouts/abc', 'src/main/res/layouts', 'src/main/res/layout', 'src/main/res' ] resources.srcDirs = ['src/main/resources', 'src/main/resources/xml'] manifest.srcFile 'src/main/AndroidManifest.xml' java.srcDirs = ['src/main/java'] } red { java.srcDirs = ['src/red/java'] res.srcDirs = [ 'src/red/res/layouts/xyz', 'src/red/res/layouts/abc', 'src/red/res/layouts', 'src/red/res' ] assets.srcDirs = ['src/red/assets'] manifest.srcFile 'src/red/AndroidManifest.xml' } blue { java.srcDirs = ['src/blue/java'] res.srcDirs = [ 'src/blue/res/layouts/xyz', 'src/blue/res/layouts/abc', 'src/blue/res/layouts', 'src/blue/res' ] assets.srcDirs = ['src/blue/assets'] manifest.srcFile 'src/blue/AndroidManifest.xml' } } } //andorid dependencies { // yout dependencies }
