Hooking into the Android plugin

When developing for Android, most tasks we want to influence are related to the Android plugin. It is possible to augment the behavior of tasks by hooking into the build process. In the previous example, we already saw how to add a dependency on a custom task to include a new task in the regular build process. In this section, we will look at some possibilities for Android-specific build hooks.

One way to hook into the Android plugin is to manipulate the build variants. Doing this is quite straightforward; you just need the following code snippet to iterate over all the build variants of an app:

android.applicationVariants.all { variant ->
  // Do something
}

To get the collection of build variants, you can use the applicationVariants object. Once you have a reference to a build variant, you can access and manipulate its properties, such as name, description, and so on. If you want to use the same logic for an Android library, use libraryVariants instead of...
