Allow Google Play Store in Walled Garden

Hello All,

MY Setup is AP------NAS-----RADIUS Server

I am trying to setup wifi environment where someone connects to open Access Point and one should register for the first time. once done I want him redirect to my App on google Play store. But he should not be able access other apps on the store. I want to enforce the user to download my app. Is it possible to allow only my app location in google play with walled Garden??

Please suggest…

Regards,
Srikanth
