LocationRequest.create().apply{ ... } is now also deprecated.

Please use LocationRequest.Builder() instead. I.E. like this:

(locationInterval, locationFastestInterval and locationMaxWaitTime corresponds to the values used before when using create())

        locationRequest = LocationRequest.Builder(Priority.PRIORITY_HIGH_ACCURACY, locationInterval)
            .setWaitForAccurateLocation(false)
            .setMinUpdateIntervalMillis(locationFastestInterval)
            .setMaxUpdateDelayMillis(locationMaxWaitTime)
            .build()

Please read more here: https://developer.android.com/reference/android/location/LocationRequest.Builder

and here: https://developers.google.com/android/reference/com/google/android/gms/location/LocationRequest.Builder

Location services were updated to version 21.0.0, and the LocationRequest.create was deprecated with the new update.

Here is how to change LocationRequest.create to recommended LocationRequest.Builder:

   fun createLocationRequest() = LocationRequest.Builder(
        Priority.PRIORITY_HIGH_ACCURACY, TimeUnit.MINUTES.toMillis(5)
    ).apply {
        setGranularity(Granularity.GRANULARITY_PERMISSION_LEVEL)
        setDurationMillis(TimeUnit.MINUTES.toMillis(5))
        setWaitForAccurateLocation(true)
        setMaxUpdates(1)
    }.build()

locationRequest = new LocationRequest.Builder(Priority.PRIORITY_HIGH_ACCURACY, 100)
                .setIntervalMillis(INTERVAL_MILLIS)             // Sets the interval for location updates
                .setMinUpdateIntervalMillis(INTERVAL_MILLIS/2)  // Sets the fastest allowed interval of location updates.
                .setWaitForAccurateLocation(false)              // Want Accurate location updates make it true or you get approximate updates
                .setMaxUpdateDelayMillis(100)                   // Sets the longest a location update may be delayed.
                .build();
