## What is it?

Each folder in `~/Library/Android/sdk/platforms` is the Android SDK for one API level (`android.jar` and related files), used when a project compiles against that level. Older levels stay installed when you raise `compileSdk`, and each typically takes from about 100 MB to a few hundred megabytes.

## What happens if you delete it?

A project that still compiles against a removed level downloads it again on the next build through the Android Gradle plugin, or you can reinstall it in the SDK Manager.

## How to remove it properly

In Android Studio, open Settings › Languages & Frameworks › Android SDK › SDK Platforms and untick the API levels you no longer compile against; or run `sdkmanager --uninstall "platforms;android-<level>"` in Terminal (permanent).
