Our project structure now looks like this: I’ve forked our original example and added these changes. ProguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'ĪpplicationId '.free'ĪpplicationId '.paid' To accomplish this, we update our adle file:ĪpplicationId '' Furthermore, let’s add debug and release build types. We’ll start with our original example but add “free” and “paid” product flavors with unique application ids. Let’s introduce a quick example to illustrate this. With all these different builds, we want to run tests on each variation, and possibly even different tests for different variations. These build variants represent the set of different ways our app is built and how it behaves. The combination of build types and product flavors create build variants. This is orthogonal to Product Flavor.īuild types define how our application is packaged, meaning that they are independent of product flavor. This concept is not meant to be used to create different versions of the same application. If not, I point again to the documentation:Ī build type allows configuration of how an application is packaged for debugging or release purpose. If you are familiar with product flavors, you’re also probably familiar with build types. A single project can have different flavors which change the generated application. He cites the documentation’s definition:Ī product flavor defines a customized version of the application build by the project. If you’re unfamiliar with product flavors, Javier Manzano has written a great explanation of product flavors and how to use them. The answer is the same as with most Robolectric-related topics: “Yes, but…” Since Roboletric 3.0 was released this week, now is a good time to explore what’s needed to set everything up. Some inquisitive commenters wanted to know if this setup supported testing multiple product flavors. In a previous blog post, I discussed integrating Android Studio, Gradle and Robolectric to perform unit testing as part of Android development.
