Hi Muthukumar,
Thanks for writing in - it's great to hear you've just completed your CleverTap integration for iOS and Android. Android requires you to explicitly enable uninstall tracking from the CleverTap Uninstall dashboard.
Once you have integrated, we do an uninstall sweep to check your entire user base once every 24 hours to see whether or not they have uninstalled your application. So, you'll need to wait for 24 hours to see your uninstalls to be reflected on the Uninstall dashboard.
Thanks,
Support.
