Android Developers. The build process for a typical Android app module, as shown in figure 1, follows these general steps: The compilers convert your source code into DEX Dalvik Executable files, which include the bytecode that runs on Android devices, and everything else into compiled resources.
The packager signs your APK or AAB using either the debug or release keystore: If you are building a debug version of your app, that is, an app you intend only for testing and profiling, the packager signs your app with the debug keystore.
Android Studio automatically configures new projects with a debug keystore. If you are building a release version of your app that you intend to release externally, the packager signs your app with the release keystore that you need to configure. To create a release keystore, read about signing your app in Android Studio.
Before generating your final APK, the packager uses the zipalign tool to optimize your app to use less memory when running on a device. Android build glossary Gradle and the Android plugin help you configure the following aspects of your build: Build types Build types define certain properties that Gradle uses when building and packaging your app, and are typically configured for different stages of your development lifecycle.
For example, the debug build type enables debug options and signs the app with the debug key, while the release build type may shrink, obfuscate, and sign your app with a release key for distribution. You must define at least one build type in order to build your app—Android Studio creates the debug and release build types by default.
To start customizing packaging settings for your app, learn how to Configure build types. Product flavors Product flavors represent different versions of your app that you may release to users, such as free and paid versions of your app. You can customize product flavors to use different code and resources, while sharing and reusing the parts that are common to all versions of your app. Product flavors are optional and you must create them manually. To start creating different versions of your app, learn how to Configure product flavors.

Make and Soong comparison Here is a comparison of Make configuration with Soong accomplishing the same in a Soong configuration Blueprint or. Modules A module in an Android.
Types Variables and properties are strongly typed, with variables dynamically based on the first assignment, and properties set statically by the module type. Globs Properties that take a list of files, such as srcs , can also take glob patterns. Variables An Android. Comments Android. Conditionals Soong doesn't support conditionals in Android. Special modules Some special module groups have unique characteristics.
Defaults modules A defaults module can be used to repeat the same properties in multiple modules. Otherwise, Soong first looks for a module named D declared in namespace N.
