Inactive GPS notification running on APP startup only

Question

Ola, I need to adjust the app I’m developing so there’s notification whenever GPS is disabled. When the app starts, if the GPS is disabled, it alerts and then starts the Switch to location settings. I happen to be using the requestLocationUpdates method of the Fusedlocationproviderclient class and, after it is started, if I disable the GPS nothing happens because 'apparently' it gets 'stuck' in the method as if it were in Loop.

NOTE: Even changing the method Looper.getMainLooper() to null in the argument of requestLocationUpdates the problem persists

This is the method that checks the GPS

private fun verificarServicoLocalizacao(): Boolean {
    val ativo: Boolean
    val gl: LocationManager = getSystemService(Context.LOCATION_SERVICE) as LocationManager
    if(gl.isProviderEnabled(LocationManager.GPS_PROVIDER)){
        ativo = true
    }else{
        Toast.makeText(this, R.string.ativar_localizacao, Toast.LENGTH_LONG).show()
        val intent = Intent(Settings.ACTION_LOCATION_SOURCE_SETTINGS)
        startActivity(intent)
        ativo = false
    }
    return ativo
}

This is the method that requests the location

private fun novaLocalizacao() {
    val locationRequest = LocationRequest()
    locationRequest.priority = LocationRequest.PRIORITY_HIGH_ACCURACY
    locationRequest.interval = 2000
    locationRequest.fastestInterval = 1000
    mFusedLocationClient.requestLocationUpdates(locationRequest,
            locationCallback, Looper.getMainLooper())
}
