I'm trying to get the context of my Service in order. The service opens up an overlay that draws on other apps. The overlay comes up but if I interact with any of the views, the app crashes and gives this error.
android.view.WindowManager$BadTokenException: Unable to add window -- token null is not valid; is your activity running?
Here is the full error.

From what I've been able to determine through Google Search and SO is that the issue is with the context. Below is the code for my Service.

I have tried several ways of getting the context, but it always seems to come back null. I have tried this, this@Dooa, this.applicationContext, I also created a class MyApp to get context that way. it didn't work either. I used this link. Code below.
class MyApp: Application() {
private var context: Context? = null
override fun onCreate() {
super.onCreate()
context = applicationContext
}
fun getContext(): Context? {
return context?.applicationContext
}
}
I've also checked out this answer about Service is a Context, but I still haven't been able to get this to work.
I have tried the code in the onCreate first then I tried the onStartCommand to no avail. What am I missing?
The window pops up, It pops up with a button click, or from a notification, either way if I click on a view, it gives me the error at the top of this question.
