Hey there! Let's work through fixing this GitLab account mix-up in Android Studio— I’ve dealt with this exact issue before, so these steps should get you sorted quickly:

• Fire up Android Studio, then head to the top menu: File > Settings (Windows/Linux) or Android Studio > Settings (Mac)
• In the settings window, navigate to Version Control > Git
• Next to the Test button, click the tiny gear icon and select Credentials
• You’ll see a list of saved Git accounts here— find the incorrect GitLab entry and delete it
• Close settings, then try pulling/pushing your project again. Android Studio will prompt you to enter the correct username and personal access token (pro tip: use a token instead of a password, it’s more secure and avoids issues with GitLab’s password restrictions)

Android Studio often uses your system’s credential manager to store account info, so we might need to clean that up too:

For Windows: #

• Open Control Panel > User Accounts > Credential Manager > Windows Credentials
• Look for entries linked to your GitLab domain under "Generic Credentials", right-click and delete them

For Mac: #

• Launch the Keychain Access app
• Search for your GitLab domain in the top search bar, find the matching credential, right-click and select "Delete"

For Linux: #

• Open your terminal and run git config --global credential.helper to see which credential helper you’re using
  • If it’s gnome-keyring or libsecret, open your system’s password manager and remove GitLab-related entries
  • If it’s store, delete the file at ~/.git-credentials

If the above steps don’t work, let’s tweak the local repo’s config directly:

• Go to your project’s root folder and find the hidden .git folder (enable "show hidden files" in your file manager if you don’t see it)
• Open the config file inside .git
• Locate the [remote "origin"] section, then update the url line to use your correct username:

  url = https://your-correct-username@gitlab.com/your-project-path.git
  

  (If you use SSH, the URL will look like git@gitlab.com:your-project-path.git— just make sure your SSH keys are set up correctly in GitLab)
• Save the file, go back to Android Studio, and try your Git operations again

A quick reminder: If you haven’t already, generate a personal access token in GitLab (under your account settings > Access Tokens) with read_repository and write_repository permissions. Using this token instead of a password will prevent future authentication headaches.
