title: How to update app on google play
body: <p>im very new to the google play and mobile app world.</p>
  
  <p>I would like to know the process of updating my app on the google play store as im not sure how. It is Android app.</p>
  
  <p>I am using xamarin for the app. I have increased the version name to by .1 and if I do this, do I have to also increase the version number to 2 ? because it cannot take decimal points.</p>
  
  <p>I have a simple understanding of It so im not sure if I have to create a new apk or update the existing one, and if so, how ?</p>
  
  <p>and then on google play, do I just go and select the new apk, or updated apk ?</p>
  
  <p>Thanks in advance</p>
