Мое приложение не запрашивает у пользователя разрешения на включение Location. Когда я вручную включаю Location, мое приложение работает должным образом, но когда я вручную выключаю Location, оно не работает должным образом и не запрашивает у пользователя разрешения на включение Location.
Вот мой Kotlin код:
override fun onRequestPermissionsResult(
requestCode: Int,
permissions: Array<out String>,
grantResults: IntArray
) {
super.onRequestPermissionsResult(requestCode, permissions, grantResults)
when (requestCode) {
REQUEST_CODE -> {
if (grantResults.size > 0) {
if (grantResults[0] == PackageManager.PERMISSION_GRANTED) {
Toast.makeText(this, "Permission Granted", Toast.LENGTH_SHORT).show()
} else {
Toast.makeText(this, "Permission Denied", Toast.LENGTH_SHORT).show()
}
}
}
}
}
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.activity_counties)
