You are using Git 0.0.0.0 which doesn't define %HOME% environment variable properly. Consider updating Git to a newer version or define %HOME% to point to the place where the global .gitconfig is stored (it is usually %USERPROFILE% or %HOMEDRIVE%%HOMEPATH%). In android studio, this error pops up at commit. What to do ?
