AGP

The Android Studio build system is based on Gradle, and the Android Gradle plugin adds several features that are specific to building Android apps

Altho the Android plugin is typically updated in lock-step with Android Studio, the plugin (and the rest of the Gradle system) can run independent of Android Studio and be updated separately

NDK

...a toolset that lets you implement parts of your app in native code, using languages like C and C++

For certain types of apps, this can help you reuse code libraries written in those languages
