Q:

How to install two different app on android device using Ionic

I am installing an app on an android device using the following command. 
"ionic cordova run android"
but when I am installing another app, it is replacing the old app. 
so please tell me the solution so that old and another new app both should be there in android device

A:

Please check the config.xml file, and change the id of the app:
<widget id="new.app.id" version="0.0.1" xmlns="http://www.w3.org/ns/widgets" xmlns:cdv="http://cordova.apache.org/ns/1.0">

That way, it will be considered as a different app and will not replace the previous one.
