What is the method for building multiple modules in Android Studio?

There are two methods for building a multi-module project in Android Studio: manual configuration and using plugins.

1. manual configuration:
2. Create multiple submodules (subdirectories) in the root directory of the project, each submodule being an independent Android application module or library module.
3. Import each submodule in the settings.gradle file in the root directory: include ‘:app’, ‘:library1’, ‘:library2’
4. Configure the build settings of each submodule in their respective build.gradle file, including dependencies, compilation options, etc.
5. Use plugins.
6. Utilize the plugins recommended by the official Android Gradle plugin, such as com.android.application and com.android.library.
7. Create a build.gradle file in the root directory of the project to configure the project’s build settings, including importing plugins and specifying version numbers.
8. Include every sub-module in the settings.gradle file in the root directory: include ‘:app’, ‘:library1’, ‘:library2’
9. Configure the build settings for each submodule in their respective build.gradle files, including dependencies, compilation options, and more.

Utilizing plugins is a relatively simple method that offers more building options and functionalities. In most cases, using plugins is the preferred approach.
