Question Detail

I have updated my Android App on Play Store. Sometimes I change in my app which is totally diffrent from the last application so when old app user use the app it got crashed. 
I want to add a AlertBox in my app for show "Your App is Live now Please Update It". But i am not able to fine any APIs which help me to get Live Android App Version Code in my coding to perform task on AlertBox Accept button.

if there is a critical update and the user has not updated yet, he cannot use the app until he does so.

Is this possible using the Play Store?
