title: Switching between branches Git on Android Studio
body: <p>I am new to Git and do not understand everything yet. I usually commit after each app update and then create a new branch for the next app version, so that I can correct bugs of the currently published version while working on improving the app for future versions.</p>
  
  <p>So far it was just a precaution and I never really used it that way but I want to get serious about Git capabilities. And I face this problem:</p>
  
  <p><strong>I have two branches in addition to the master, and if I compare the files from the two branches, I can clearly see the differences.
  However, if I "checkout" from one branch to the other, nothing happens and it seems that the current code is just reassigned to a different branch.
  But what I want to do is to be able to modify both codes in parallel.</strong></p>
  
  <p>How does it work?</p>
  
  <p>Thanks.</p>
