I have been working on an Android Studio Project using the Google Developers Console, the Firebase Developers Console, and Android Studio Google Maps, using Java Code to obtain Real Time Location Awareness for the apk file to publish on the Google Play Store, using the Google Merchant Account.  Following are some screen shots of the progress, and how things are progressing.

1) This code snippet shows how to utilize "Shared Preferences" to store persistent storage within the Android Application Activity

 

The editor.commit writes the values with putString into the Shared Preferencces

This code snippet tests whether the PREFS_NAME exits, and if it does from data input by the user writes the data to the Activity

This is before USER data input

This is what prompts the user, it is an Alert Dialog widget with EditText and TextView elements

This demonstrates input by the User for the values to be commited to Shared Preferences

This shows the Shared Preferences written to the Activity, and saved in the Shared Preferences

Using the Calendar Widget, and Java Code, the user can select a date to generate the logbook sheet from the values that have been saved in the Firebase Database in the Cloud

This is the result of obtaining the date from the calendar, then parsing the Firebase database to set the graphics within the Android Studio Activity to produce a logbook sheet for the date selected
