Install Android Studio on an external SSD for Flutter
When I work in the office I use a desktop with a one terabyte Fusion drive. That is plenty of storage for my development needs. On the laptop I use when I work from home, on the other hand, the available storage is low. Too low to run all the development tools I need.
For this reason, I decided to install Android Studio on an external SSD.
I downloaded it from the official website, moved it to the SSD, which I named Skynet, and launched it.
During installation I chose a custom setup, to set the location of the Android SDK to a folder in the SSD.
Then I run flutter doctor, but I got the error Android license status unknown.
So I run flutter doctor --android-licenses, which gave me a very weird message.
flutter doctor --android-licenses

After a quick Internet search, I opened Android Studio and clicked Configure.
And I added two packages:
- NDK (Side by Side)
- Android SDK Command-line Tools (latest)
I guess only the command-line tools are needed.
At this point flutter doctor --android-licenses worked as expected, but flutter doctor still complained that Android Studio was not installed.

So I run flutter config --android-studio-dir /Volumes/Skynet/Android\ Studio.app, and finally, no errors.
