The document discusses 3 ways to implement location tracking in Android applications efficiently. Requesting one-shot location updates is suitable when location is needed on a few screens. A timer/service approach can track location continuously by starting and stopping updates on a timed interval. A geo-fence based approach uses geo-fences to monitor location, creating new fences when the user exits the existing one, providing continuous tracking with better battery optimization than other methods. The best approach depends on the application's specific location tracking needs.
