3. Run the app on your mobile phone or emulator with Google Play Services on it.

1.androidTest
        RemindersDaoTest - tests the RemindersDao methods to ensure that read / write / delete operations function as expected.
        RemindersLocalRepositoryTest - Integration test between the RemindersLocalRepository and RemindersDao s' methods to ensure that read / write / delete operations function         as expected.
        ReminderListFragmentTest - tests the reminder's navigation functionality as well as the data ,available in the UI, to ensure that read/write/delete UI-related operations
        function as expected and error-containing snackbar is displayed if applicable.
        RemindersActivityTest - end-to-end black box test for the RemindersActivity , to ensure that the UX is smooth and the proper data and widgets are present in the UI               during specific user interactions.
        
2. test
      RemindersListViewModelTest - tests the methods of the RemindersListViewModel and the LiveData's values to ensure that read/write/delete operations deliver the expected           output and error values are produced where applicable.
      SaveReminderViewModelTest - tests the methods of the RemindersListViewModel and the LiveData's values to ensure that read/write/delete operations deliver the expected           output and error values are produced where applicable.
      

1. Create a Login screen to ask users to login using an email address or a Google account.  Upon successful login, navigate the user to the Reminders screen.   If there is no account, the app should navigate to a Register screen.
2. Create a Register screen to allow a user to register using an email address or a Google account.
3. Create a screen that displays the reminders retrieved from local storage. If there are no reminders, display a   "No Data"  indicator.  If there are any errors, display an error message.
4. Create a screen that shows a map with the user's current location and asks the user to select a point of interest to create a reminder.
5. Create a screen to add a reminder when a user reaches the selected location.  Each reminder should include
    a. title
    b. description
    c. selected location
6. Reminder data should be saved to local storage.
7. For each reminder, create a geofencing request in the background that fires up a notification when the user enters the geofencing area.
8. Provide testing for the ViewModels, Coroutines and LiveData objects.
9. Create a FakeDataSource to replace the Data Layer and test the app in isolation.
10. Use Espresso and Mockito to test each screen of the app:
    a. Test DAO (Data Access Object) and Repository classes.
    b. Add testing for the error messages.
    c. Add End-To-End testing for the Fragments navigation.
