The Android SDK folder holds platforms, build tools and system images for emulators. System images are the big part, 1–4 GB each. Remove the ones you don’t use from Android Studio’s SDK Manager rather than deleting folders, so Studio stays consistent.

The right way
In Android Studio, open Settings › Languages & Frameworks › Android SDK, untick system images and platforms you don't need, and apply. Delete unused virtual devices in Device Manager; their data lives in ~/.android/avd.

TidyMac lists big folders outside its library, checks which app owns each one and whether that app is still installed, and explains it.
