In this chapter, we discussed and learned about creating our own LBA. We understood the details of the Google Maps API, the generation of API keys, the creation of the user interface for maps, adding markers to the map, customizing the marker, creating user interface screens for input from the user, and so on.

We also discussed the important components in the manifest file, the build.gradle file, and the XML layout files and corresponding Kotlin classes. In the next chapter, we will save the input we received from the user using shared preferences, use the location-based services from Google APIs, and enable and trigger the alarm as and when the user enters the location.
