I am not able to get the solution please if anyone know the issue reply

Tizen is backwards compatible OS but it is not forward compatible so it you have a watch running Tizen 4.0 you cannot install an app at level Tizen 7.0 in that watch. You have to use the Tizen 4.0 API.

If you are talking about a Smart TV app See this list

I really need to understand what platform you are developing for.
