How to reset Android Studio

I only know how to do this on Windows (but it should be similar on any OS, you will just need to find the correct location yourself - google search would help with that).

On Windows:

Go to your User Folder - on Windows 7/8 this would be:

[SYSDRIVE]:\Users\[your username] (ex. C:\Users\JohnDoe\)

In this folder there should be a folder called .AndroidStudioBeta or .AndroidStudio (notice the period at the start - so on some OSes it would be hidden).

Update

Now, Android Studio settings is at:

C:\Users\<Your User>\AppData\Roaming\Google\.AndroidStudio4.X

Delete this folder (or better yet, move it to a backup location - so you can return it if something goes wrong).

This should reset your Android Studio settings to default.

On Mac OS X

Remove these directories:

~/Library/Application Support/AndroidStudioBeta
~/Library/Caches/AndroidStudioBeta
~/Library/Logs/AndroidStudioBeta
~/Library/Preferences/AndroidStudioBeta

From Linux this is what I did:

Remove the .AndroidStudioBeta folder:

rm -r ~/.AndroidStudioBeta

Remove the project folder. For example:

rm -r ~/AndroidStudioProjects

I needed to do both or stuff kept hanging around.

Hope this helps.

Linux

Android Studio 4.2:

rm -rf ~/.config/Google/AndroidStudio*
rm -rf ~/.local/share/Google/AndroidStudio*
rm -rf ~/.cache/Google/AndroidStudio*

Android Studio 1.0.0:

rm -R ~/.AndroidStudio/config/

Android Studio 0.8.6:

rm -R ~/.AndroidStudioBeta/config/

On Mac OS X with Android Studio >= 1.0.0

Run these lines:

rm -rf ~/Library/Application Support/AndroidStudio
rm -rf ~/Library/Caches/AndroidStudio
rm -rf ~/Library/Logs/AndroidStudio
rm -rf ~/Library/Preferences/AndroidStudio

Linux AnddroidStudio 1.1.0

rm -r ~/.AndroidStudio

For MaxOSX:

rm -rfv ~/Library/Application\ Support/AndroidStudio*
rm -rfv ~/Library/Preferences/AndroidStudio*
rm -rfv ~/Library/Caches/AndroidStudio*
rm -rfv ~/Library/Logs/AndroidStudio*
rm -rfv ~/.AndroidStudio*

For Android Studio 1.2.2 version, config path is ~/Library/Application\ Support/AndroidStudio1.2/ and ~/Library/Preferences/AndroidStudio1.2, so it's better to rm matching prefix.

Build - Clean project. Basically, this is a problem with studio 3.0. https://developer.android.com/studio/build/gradle-plugin-3-0-0.html (authorized link).

Windows Users: Look for C:->Users->YourUserName->.AndroidStudio or .AndroidStudioBeta folder. Delete that.

Mac Users: Delete these using the terminal (usage: rm -rf folderpath): ~/Library/Preferences/AndroidStudioBeta ~/Library/Application Support/AndroidStudioBeta ~/Library/Caches/AndroidStudioBeta ~/Library/Logs/AndroidStudioBeta

Linus Users: Delete these using the terminal (usage: rm -r folderpath): ~/.AndroidStudioBeta/config or ~/.AndroidStudio/config

On a Mac

Delete these using the terminal (usage: rm -rf folderpath):

~/Library/Preferences/AndroidStudioBeta
~/Library/Application Support/AndroidStudioBeta
~/Library/Caches/AndroidStudioBeta
~/Library/Logs/AndroidStudioBeta

1. Open Home
2. Press Ctrl+H (to show hidden files)
3. Delete AndroidStudio setting folder (like image below)
4. Restart Android Studio

We can no longer reset android studio to it's default state by the answers/methods given in this question from android studio 3.2.0 Here is the updated new method to do it (It consumes less time as it does not require any update/installation).

For Windows/Mac

1. Open my computer

2. Go to C:\Users\Username\.android\build-cache

3. Delete the cache/files found inside the folder build-cache

4. Note: do not delete the folder named as "3.2.0" and "3.2.1" which will be inside the build-cache

5. Restart Android studio.

and that would completely reset your android studio settings from Android studio 3.2.0 and up.

If you are using Windows and Android Studio 4 and above, the location to the directory is C:\Users(your name)\AppData\Roaming\Google\

Simple delete the Google folder to reset all settings. Open Android Studio and do not import settings when asked

close project if not done earlier or working on a new project. Now open android studio and click on the configure settings button available at the bottom of the small window of android studio, there you will see restore settings to default option. The safe way to do it.

You can reset it via menu: File > Manage IDE Settings > Restore Default Settings

On MAC delete this folder:

~/Library/Application Support/Google/AndroidStudio4.1

Open Android Studio > Configure > Restore default settings ...

for ( Android Studio Version >= 3.0.0 & macOS)

mine( Android Studio Dolphin | 2021.3.1 Patch 1 & macOS 12.6)

To reset Android Studio back to its default:

1. Open Android Studio and click on "File," located in the lower left-hand corner of your screen.

2. From the list of settings that appears, locate the option for "Restore Default Settings."

Resetting Android Studio to its default settings removes any changes and caches you have made to your settings and allows you to start fresh as if Android Studio was a brand-new installation.
