title: Does Compiling My Android App On A Different Computer Create A New Signing Certificate?
body: <p>I created an app on my Windows PC and from that PC I published the app to the Google Play Store. I have migrated(transferred via external hard drive) all my projects from my PC to my Mac. </p>
  
  <p>I am now wondering will compiling that same app on the Mac cause it to create a new certificate?</p>
  
  <p>The reason I would like to know is because I want to publish an update and would prefer to work on the project on the Mac but I don't want a problem to occur, that when I decide to publish the app from the Mac the Play Store will see a different certificate and the app will be published as if it were a totally brand new APK.</p>
