In this project, you will create a TODO list app with location reminders that remind the user to do something when the user is at a specific location.

The app will require the user to create an account and login to set and access reminders.

• Create Login and Registration screens:
  • Login screen allows users to login using email or a Google Account
  • If the user does not exist, the app navigates to a Registration screen
• Enable user accounts using Firebase Authentication and Firebase UI.
  • The project includes a FirebaseUI dependency
  • Authentication is enabled through the Firebase console.

• Create a Map view that shows the user's current location
  • A screen that shows a map and asks the user to allow the location permission to show his location on the map.
  • After user granted permission, move camera to current user location.
  • The app works on all the different Android versions including Android Q.
• Add functionality to allow the user to select POIs or any locations to set reminders
  • The app asks the user to select a location or POI on the map and add a new marker at that location
  • Upon saving, the selected location is returned to the Save Reminder page and the user is asked to input the title and description for the reminder.
  • When the reminder is saved, a geofencing request is created.
• Style the map
  • Map Styling has been updated using the map styling wizard to generate a nice looking map.
  • Users have the option to change map type: MAP_TYPE_NORMAL, MAP_TYPE_HYBRID, MAP_TYPE_SATELLITE, MAP_TYPE_TERRAIN
• Display a notification when a selected POI is reached
  • When the user enters a geofence, a reminder is retrieved from the local storage and a notification showing the reminder title will appear, even if the app is not open.

• Add a screen to create reminders
  • Reminder data includes title and description.
  • The user-entered data will be captured using live data and data binding.
  • RemindersLocalRepository is used to save the reminder to the local DB. And the geofencing request will be created after confirmation.
• Add a list view that displays the reminders
  • All reminders in the location DB is displayed
  • If the location DB is empty, a no data indicator is displayed.
  • User can navigate from this screen to another screen to create a new reminder.
• Display details about a reminder when saved locations are reached and the user clicked on the notification.
  • When the user clicks a notification, when he clicks on it, a new screen appears to display the reminder details.

• Test the ViewModels, Coroutines, and LiveData
  • RemindersListViewModelTest or SaveReminderViewModelTest are present in the test package that tests the functions inside the view model.
  • Live data objects are tested using shouldReturnError and check_loading testing functions.
• Create a FakeDataSource to replace the Data Layer and test the app in isolation.
  • Project repo contains a FakeDataSource class that acts as a test double for the LocalDataSource.
• Use Espresso and Mockito to test the app UI and Fragments Navigation, Tests include:
  • Automation Testing using ViewMatchers and ViewInteractions to simulate user interactions with the app.
  • Testing for Snackbar and Toast messages.
  • Testing the fragments’ navigation.
  • The testing classes are at androidTest package.
• Test DAO and Repository classes:
  • Testing uses Room.inMemoryDatabaseBuilder to create a Room DB instance.
  • Testing covers:
    • inserting and retrieving data using DAO.
    • predictable errors like data not found.

• MVVM + ViewModel + LiveData + Data Binding
• Room Database
• Kotlin Coroutines
• Navigation component between Fragments
• Maps SDK for Android - Display Google Map, click on Point of Interest.
  • Custom Google Map Style
  • Get device location , move camera to current user location.
• Location permission: Manifest permission & Runtime permission
• Geofencing API - Provide contextual experiences when users enter or leave an area of interest.
• Local Test, Instrument Test using Mockito and Espresso.
• Koin - A pragmatic lightweight dependency injection framework for Kotlin.
• FirebaseUI Authentication - FirebaseUI provides a drop-in auth solution that handles the UI flows for signing.
• JobIntentService - Run background service from the background application, Compatible with >= Android O.
