Disable "sleep mode" on Tizen TV when app active - xamarin.forms

I create my first app for Tizen (with Xamarin Forms). When i run my app i need TV to stay all time active.
While the app is on, the sleep mode should not turn on on the TV.
Is it possible?
What api should I use?

Not a direct solution, but a way to go:
implement a possibility to call tizen native code from forms: https://stackoverflow.com/a/53534562/7149454
call tizen native api to set efl_util_set_window_screen_mode(win,EFL_UTIL_SCREEN_MODE_ALWAYS_ON);

iOS List of Installed Apps by User || XAMARIN FORMS

I am creating an iOS application using Xamarin Forms which is a copy of an Android application written in Kotlin.
There is a section that lists all the applications installed in the current device by the user. I want to implement the same functionality in the iOS application too.
Is it possible to get the applications list in iOS through Xamarin Forms?
This is impossible on iOS and it is not possible on Android either if you target latest API levels, so in some future when those API levels become required on Google Play you won't be able to do this.
This is a huge privacy issue, as having the list of apps may reveal something very personal and private and as soon as the app has it there is nothing that prevents it to send the info to the 3rd party server.

Push Notification in Xamarin forms PCL Project

I have created a Xamarin Forms PCL Project.
I have a SQL Server database and when my database table is updated, I want to generate a Push Notification for my Android as well as IOS Application.
I don't want to request the table again and again. Is there any other way?
I recommend using the azure but if you do not want to pay, uses Onesignal is free and works for android and ios.
For onesignal, here is a tutorial:
https://julianocustodio.com/2017/11/21/onesignal-push-notification/
You need to write background service in android & iOS which will keep checking the table in database after fixed intervals of time and will generate notifications from it.
Also you need dependency service so that you can call platform specific services from Xamarin.Forms

Adobe AIR application to receive back events from native Windows application

I'm trying to develop a simple mxml Flex application to start Skype from the AIR/Flashplayer runtime. Is it possible to get back events from a native Windows application? In the simple example of Skype, the OS returns control to the Flex app when Skype exits. But what about native applications which have their own event model and wants to communicate with the Flex event model. For example, a Face detection system which shows "Hello" on a Flex app when the camera detects a face. Can this be done in the current Flex framework?
You'll have to use a NativeProcess to get data / info back from a native windows application.
