I've solved the problem , and I will explain how :
Download Github For Windows client and install it.
After The client successfully installed , connect it with your github account.It should be easy , just follow the wizard.
Then you should add git.exe location to your "Path Variable". The location you should add will probably be something like : C:\Users\Your_Username\AppData\Local\GitHub\PortableGit_ca477551eeb4aea0e4ae9fcd3358bd96720bb5c8\bin
Alternatively , if you don't want to add to environment variables. You can open the android studio and go to : Settings -> Version Control -> Git In text box next to "Path to Git Executable" you will see "git.exe" , just give it a full path like so : C:\Users\Your_Username\AppData\Local\GitHub\PortableGit_ca477551eeb4aea0e4ae9fcd3358bd96720bb5c8\bin\git.exe
EDIT : For latest Github for windows versions some can find the git.exe under "...\cmd\git.exe" rather than "...\bin\git.exe". // . for my try, is this location not portabelgit\bin\git.exe.
