How do I free space used by Android Studio and its emulators?

Short answer: Delete unused emulators in Device Manager, remove old platforms and system images in SDK Manager, and clear ~/.gradle/caches if needed (dependencies re-download).

Android development stores large data in a few places:

  • Emulators (AVDs) — delete unused ones from Android Studio's Device Manager; each can be many gigabytes.
  • SDK packages — remove old platforms and system images in the SDK Manager.
  • Gradle caches — in ~/.gradle/caches; clearing them means dependencies re-download on the next build.

Quit Android Studio before deleting anything by hand.
