I made a project on Android Studio and pushed the file to Github. My colleagues could pull that project and could work. I've made a few changes in the project myself, committed but when i push, it gives me the following error
Push rejected: Push to origin/master was rejected
I'm working on linux
I tried git push -u origin master and i get the following error
    To https://github.com/devilape/Iimpacttest.git
     ! [rejected]        master -> master (non-fast-forward)
    error: failed to push some refs to 'https://github.com/devilape/Iimpacttest.git'
    hint: Updates were rejected because the tip of your current branch is behind
     hint: its remote counterpart. Integrate the remote changes (e.g.
     hint: 'git pull ...') before pushing again.
     hint: See the 'Note about fast-forwards' in 'git push --help' for details.
