[macos] How to completely uninstall Android Studio on Mac?

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 it completely from my mac. I tried to delete it from my mac and then install it again as if you would do the first time, but it did nothing and now the same problems occur.

How can I manage to remove it completely and install a fresh one again?

For someone using Android Studio 4.0 or above on MacOS 10.15.1 or above. Using command line blow:

# Deletes the Android Studio application
# Note that this may be different depending on what you named the application as, or whether you downloaded the preview version
rm -Rf /Applications/Android\ Studio.app
# Delete All Android Studio related preferences
# The asterisk here should target all folders/files beginning with the string before it
rm -Rf ~/Library/Preferences/Google/AndroidStudio*
# Deletes the Android Studio's plist file
rm -Rf ~/Library/Preferences/com.google.android.*
# Deletes the Android Emulator's plist file
rm -Rf ~/Library/Preferences/com.android.*
# Deletes mainly plugins (or at least according to what mine (Edric) contains)
rm -Rf ~/Library/Application\ Support/Google/AndroidStudio*
# Deletes all logs that Android Studio outputs
rm -Rf ~/Library/Logs/Google/AndroidStudio*
# Deletes Android Studio's caches
rm -Rf ~/Library/Caches/Google/AndroidStudio*
# Deletes older versions of Android Studio
rm -Rf ~/.AndroidStudio*

Difference

Library/Preferences/Google/AndroidStudio*

Library/Logs/Google/AndroidStudio*

Library/Caches/Google/AndroidStudio*

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).

I was also facing same kind of problem on my Macbook Pro. I took these very simple steps and freshly installed Android Studio.

These Very Simple Steps Can Solve Your Problem.

1. Type "Command+option+Space Bar"
2. Type "Android Studio"
3. Click '+' button just below search box.
4. A new bar will come up "Kind" is "any" click on "kind" --> Others --> search for "system file" and select that by putting a tick mark.! And click on Ok.
5. Then select "are included" from the drop down menu !
6. Then you get a lot of system file that need to be deleted to complete the fully un-installation of any app.
7. Click "command+A" to select all files and take a look on the file remove is some video files are also included. And click "command + Delete"
8. Empty your trash. Done

Run the following commands in the terminal:

rm -Rf /Applications/Android\ Studio.app  
rm -Rf ~/Library/Preferences/AndroidStudio*  
rm -Rf ~/Library/Preferences/com.google.android.*  
rm -Rf ~/Library/Preferences/com.android.*  
rm -Rf ~/Library/Application\ Support/AndroidStudio*  
rm -Rf ~/Library/Logs/AndroidStudio*  
rm -Rf ~/Library/Caches/AndroidStudio*  
rm -Rf ~/.AndroidStudio*  
rm -Rf ~/.gradle  
rm -Rf ~/.android  
rm -Rf ~/Library/Android*  
rm -Rf /usr/local/var/lib/android-sdk/  

To delete all projects:

rm -Rf ~/AndroidStudioProjects  

You may also delete gradle file, if you don't use gradle any where else:

rm -Rfv ~/.gradle/

because .gradle folder contains cached artifacts that are no longer needed.
