It’s easy enough to find out that you should modify either the ANDROID_SDK_ROOT, ANDROID_EMULATOR_HOME, or ANDROID_AVD_HOME environment variables (or even ANDROID_HOME, if you’re unlucky enough to find some really outdated documents). It’s possible, but if you’re lucky like I am, you might run into some hurdles. Imagine you’d like to reclaim space on your Mac’s main hard drive by moving your Android Studio Virtual Devices (the phones and tablets you run in the Android Emulator to test your applications).
