Ya you for test you need to change your app’s package name to to any existing app in play store like me I changed package name to flipkart’s package name which is com.flipkart.android and version code and version name to 1 and 1.0 and export apk I think it doesn’t work in companion and make sure your test app’s package name do not have to match any existing app I mean if package name is flipkart then you have to uninstall original flipkart otherwise you get app not installed error See below screenshot.
Thanks.
