Learn about product flavors, build types, build variants, and other components of the Gradle build system, and why it is important to In-app Billing.
- [Instructor] Before we can implement Google's in-app billing functionality, there are a couple of requirements that we need to be aware of which require us to look at the build system for solutions. The first is that in-app purchases must be made on a production release APK. Making a production release APK involves two steps. The first is creating a product flavor and the other step is to create a build type and we will learn how to do both in this section.
Next, the Android build should be secured. One of several methods to make the app more secure is to use code obfuscation and we will look at how to do that also in our Gradle build system. Making a signed production release APK can be broken down into two parts and the first is creating a public key certificate and incorporating it into the production release APK and then finally building the production release APK.
Managing the public key certificates will be part of the signing config and we will create a signing config in our Gradle build system. We will also learn how to define product SKUs as part of our build config and finally we will learn also how to rename the APK using our Gradle build system.
