Hello,
Is it possible to check wheather app or channel is installed or unstilled by code so that when user unstilled channel and again installed they we can redirect to them for login or register but now when they installed previously and unstill after so period of time and again installed then it directly redirectsto home page so we want to avoid this

It sounds like you might want to check the Roku Single Sign On functionality here https://sdkdocs.roku.com/display/sdkdoc/Roku+Federated+Identity+Single+Sign-On
In the past Roku hasn't notified anyone when a channel is uninstalled, or even when a channel has been installed. But Single Sign-on might provide a part of what you are asking for here.
