I have been looking for a while (on the Roku SDK docs, on this forum, on Stackoverflow, and on the web), whether the Roku SDK has any APIs or components that would channel developers to ask channel users for ratings. So far, I have found no one else discussing this topic directly (perhaps I am not using the correct search terms: roku sdk channel application ratings, and multiple other combinations and permutations.)
To be explicit, what I am trying to do (in my Scene Graph application, using no deprecated components) is to ask the user for a rating of my channel after they have used it at least a couple of times. What I would find useful is to embed some official Roku SDK component, or invoke some official API, inside my application; if that isn't available, perhaps use a button that will take the user to the Roku Channel Store where they can set their rating freely; or any alternative to that effect, replicating what developers do in their applications for mobile devices.
Obviously, I do not want to interfere in any way with the honest ratings of my channel users. Perhaps something like this is not available, or even discussed, because asking for ratings is not something that is normally done for applications in the Roku ecosystem?
