I am trying to push android project to private empty repo with android studio . But I cannot find simple solution. How can I do this ?
Github helpfully provides a guide for adding an existing code base into a repository which already exists, here. Whilst not specific to android studio, it will allow you to use whatever normal commit method you use.
In a nutshell:
git init
git add .
git commit -m "your commit message"
git remote add origin your@git:repo/name
git remote -v
git push origin master
