Aapt2 explains:

AAPT is the full name of Android asset packaging tool. It is an indispensable tool to build app and even Android system. Its function is to compress and package all resource files into Android APK. We can find it in the Android SDK directory. For example, I can find it in my directory D: SDK, build tools, 28.0.2, and other versions of build tools;

Aapt2 is a new version of AAPT. Starting from Android studio 3.0, it is used as the default resource packaging tool.
