Build an Android app that monitors the user's location and then records this information to a Firebase database, so you can view the device's exact coordinates in realtime.

Google has acquired backend-as-a-service startup Firebase, maker of a development platform for building Android and iOS apps that can store and sync data in real time.

Google is also rolling out a new user interface that makes it easier to understand the data in Firebase Predictions, a machine learning-based service that predicts app users’ future behavior.
