How to completely uninstall Android Studio on Mac?

Question

I recently downloaded Android Studio on my Macbook Pro and I messed up with it every time I open it. It gives me plugin errors and several other errors. I need to uninstall

Answer 1

Some of the files individually listed by Simon would also be found with something like the following command, but with some additional assurance about thoroughness, and without the recklessness of using rm -rf with wildcards:

find ~ \
  -path ~/Library/Caches/Metadata/Safari -prune -o \
  -iname \*android\*studio\* -print -prune

Also don't forget about the SDK, which is now separate from the application, and ~/.gradle/ (see vijay's answer).
