title: Android github push and pull
body: <p>First time using git and github for my small android project that I will be the base user. The rest of the team will have to submit a  <code>pull request</code> for me to review.</p>
  
  <p>I created a project and have the others forked the project. When I committed and pushed new content to my repo and notify my team members to update their copy.
  They clicked the blue down arrow on android studio but they can't seems to be able to update by pulling from me? It just says the "All files are up to date".</p>
  
  <p>They are also not able to push. <code>"Failed with error: fatal: unable to access 'https://github.com/groupmemberusername/project.git/': The requested URL returned error : 403"</code> </p>
  
  <p>From my understanding is that a <code>pull request</code> is something for you to notify the original base repo creator(which is me) to review and thus decide whether to merge the changes to the original repo. Is this understanding wrong?</p>
