How can I use multiple accounts with Telegram? There is a question here but that is for Ubuntu on PC.
I have the same question for an android device.


  Is there a way to have two copies of telegram app in Android each with
  a different account?  


I'm using the version Kitkat 4.4.
Use the Parallel Space app. Using this app, you can run more than one copy of almost any app. Here is a link to the app: https://play.google.com/store/apps/details?id=com.lbe.parallel.intl
