Git in Android Studio disappeared?

In my case the plugins "Git" and "GitHub" ware disabled. I enabled them (Settings->Plugins->Installed) and menu "Git" had been appeared.

Try this way ,

1. In Android Studio enable the version control for the project by, VCS –> Enable Version Control Integration
2. Open command line/terminal and add the project to Git repository by, git remote add
3. Add files by, VCS –> Git –> Add and commit/push by, VCS –> Commit Changes

Checkout Android Studio Git Tutorial link for more detail.

as well as check this Stack Explaination.

In Android Studio, go to ‘File’ –> ‘Settings’ –> ‘Version Control’ –> ‘Git’. Then click ‘Test’ to ensure that Git is configured properly in Android Studio.

Prior to using Git or any other version control with an existing project, ‘version control integration’ should be enabled. In Android Studio, got to ‘VCS’ –> ‘Enable Version Control Integration’. This step is for an already existing project in Android Studio, that is not is integrated with any version control.

Try this:

Settings -> Plugins -> Install JetBrains Plugin -> Type "Git" on search

Then Install: VCS Annotations Preloader

Hope this process will solve your problem
