# Remote SDK configuration

Starting in SDK versions `3.16.0`, the SDK can be remotely configured through the [dashboard](https://dashboard.radar.com/settings#sdk-configuration). Configurations are targeted by OS and environment. With these configuration options, a typical tracking implementation requires only calling `Radar.initialize()` and, optionally, `Radar.setUserId()`.

### Track once on initialize

When enabled, the SDK will automatically perform a `Radar.trackOnce()` call when the app is launched or foregrounded.

### Start tracking on initialize

When enabled, the SDK will automatically start tracking with `Radar.startTracking()` when the app is launched.

### Log level

Set the SDK log level. Overrides any log level set client side.

## Remotely set tracking options

You can remotely set SDK [tracking options](/sdk/tracking) with either the default presets or a custom configuration. Remotely setting tracking options overrides any client-side specified tracking options.

In addition to the general tracking options, on-trip tracking options apply when a user is on a trip and in-geofence tracking options allow you to dictate different tracking options for when users are in geofences with the tags specified.

### Custom tracking options

Custom configurations should declare all tracking options in JSON. Example custom tracking options are below.
