Is there such a link ( http://refspecs.linuxfoundation.org/FHS_2.3/fhs-2.3.html ) that explains the folders inside the main Android SDK folder?
Based on the answer I have received so far, I think I need to clarify what I'm looking for.
I wanted to know the basis for the SDK, which will be divided into these folders (screenshot below). For example, something similar to the following excerpt in the "Readme.txt SDK"
"Platform-tools contains build tools that are periodically updated to support new features on the Android platform (therefore, they are separated from the basic SDK tools), including adb, dexdump, and others."

I put a copy of the android-sdk folder in a folder separate from the IDE so that it can be shared.
