No location to return for getLastLocation() / java.util.NoSuchElementException

[youlovejohnny]

Hello! I'm trying to get last location: Manifest:

    <uses-permission android:name="android.permission.INTERNET" />
    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
    <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />

Function:

    fun getNewLocation(): Single<Location> {
        if (EasyPermissions.hasPermissions(context, Manifest.permission.ACCESS_FINE_LOCATION)) {
            val locationProvider = ReactiveLocationProvider(context)
            return locationProvider.lastKnownLocation.singleOrError()
        } else {
            throw Throwable("No permission")
        }
    }

But i got error:

W/GCoreFlp: No location to return for getLastLocation()

All permissions are granted, other applications are working (e.g google maps) Whats wrong?

Asus ZC600KL (asus zenfon 5 lite) 7.1 android

All works on emulator, asus 520 (7.0), xiaomi mi 8 se (9.1), samsung s7 (8)

Hi, sometimes lastKnownLocation is not available and location provider just returns null. That's why getLastKnownLocation() method returns Maybe and not Single. Forcing maybe to become single throws NoSuchElementException in case it is empty. If lastKnownLocation is not available you have to fetch location differently.
