useSupportLibrary

useSupportLibrary is a boolean value found within the Android project's Gradle build files, specifically in the `build.gradle` module-level file. When set to true, it indicates that the project intends to utilize Android Support Libraries. These libraries provide backward compatibility for older Android versions, allowing developers to use newer Android features and APIs on devices running older operating system versions. They also offer enhanced UI components and tools that are not part of the core Android framework. Setting useSupportLibrary to false means the project will not include or rely on these backward compatibility libraries. The decision to set this value is typically made during project creation or when migrating an older project. In modern Android development, the use of AndroidX libraries, which are the successor to the original Support Libraries, is now the recommended approach. AndroidX offers a more organized and consistent namespace for compatibility and Jetpack components. Therefore, while useSupportLibrary was historically important, its relevance has diminished with the adoption of AndroidX.
