So I'm using Google Maps in my Android app for a country picker but I keep getting this error:
`Java.lang.IndexOutOfBoundsException: Index: 0, Size: 0`

How can I prevent this kind of error? I think the problem comes from here:
```val address = geocoder.getFromLocation(it.latitude, it.longitude, 1)
val country = address[0].countryCode.toLowerCase()```

```
address.gerOrNull[0]?.countryCode?.toLowerCase().orEmpty()

val country = if (address.isNotEmpty()) address[0].countryCode.toLowerCase() else ""
```
