I have this issue where every time when create a new user account, it replace the current user that is already signed in.
you should use push() method. Push is creating new id for every entry so data cannot be overwritten.

I have an app that accepts shared data from other apps.
So in my onCreate(...) function, I have
intent.extras?.getString("android.intent.extra.TEXT")?.let{query -> someCallback(query)}
This works fine if my app has not been started yet. However, I also want to call someCallback when data is shared after my Activity has already been created? How do I hook into the event of receiving shared data from another app?

I want user to input some information on the first time they start the app so that those information can be used from that on. What are the possible ways to do this?
if you are looking at storing large or complicated data you can save it with room database. if you need to store simple data you can use shared preferences.
you can save a variable in shared preferences such as isFirstTimeUser=true or false then you can check this variable when the app starts. If it is the users first time to use the app present them with ui to create the fields you require. If not then proceed to fetch the details

Its not clear why you want to use firebase and for what purpose. I mean how you want to use firebase here. Please give some more detail about it.
Set the value like is_admin == 1 and is_doctors == 2 and is_patients == 3 and please give some more detail about it.

I have below FireStore data
And I have a list specialUsers which is defined as
val specialUsers = arrayOf("stark#gmail.com", "lannester#gmail.com")
So I want to get collections which are in the specialUsers, something like
collection("users").whereIn(specialUsers)
But, couldn't find any documentation related to this. How can I perform above intention in Firestore?
As he says here in 6:19
There is still no way for the database to automatically grab specific user name and profile for each review as I requesting them. I would need to make separate database request for every single review I get to fetch this information and that's bad. so If we wont to automatically include information about who rote a particular review we will need to copy sample of the user profile to the particular review and this is the way (to brake data Normalization) specifically in could FireStore.
