How to wait for onMapReady to do all the processing before the onActivityResult is called in android activity?

I'm trying to call startActivityForResult() and do the processing in the onActivityResult(). I've also implemented onMapReady() callback, which is initalizing variables and states of the activity and doing some processing. The problem is I can't access variable (getting nullpointerexception) which will be used for some processing in the onActivityResult(), because the onActivityResult() is called before the onMapReady() finished (it's async). I want to know how to wait for the onMapReady() finish before accessing onActivityResult().

I've looked into this solution, but I can't call onActivityResult() manually. How to pause at an Android lifecycle stage until callback is called?

Is there anyway I can hook the lifecycle events and start onActivityResult() after the onMapReady()?

why don't you use global variables?

see this for example:

var isMapReady = false
var onActivityResultCalled = false
fun doProcesses(){
    
}

override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) {
    super.onActivityResult(requestCode, resultCode, data)
    if (isMapReady.not()) {
        onActivityResultCalled = true
    } else {
        doProcesses()
        onActivityResultCalled = false
    }
    
}

@Override
public void onMapReady(GoogleMap googleMap) {
    isMapReady = true
    if (onActivityResultCalled) doProcesses()
}
