The Alpha Fitness app (Figure 1) has several Activities. The first Activity that will be launched at the start time is RecordWorkout Activity.

It has a fragment for portrait mode and a fragment for landscape mode. When RecordWorkout is in the portrait mode, the user can press the Start Workout button. Once clicked, the Start Workout button becomes the Stop Workout button. The distance and duration of the workout will be recorded in real time and shown on the screen.

The route for the user will be recorded using Android’s GPS services and shown on Google Map. When the user rotates the screen, the Record Workout Activity goes into the landscape more. The Workout Details fragment will be shown.

In the Record Workout Activity, there is the User Profile button. When the user clicks on this button, the second Activity screen for user profile will be activated. User can edit name, select gender and input weight information. The same screen also gives summaries such as weekly average and all time total for distance, time, number of workouts and calories burned. User can use the Android’s Go Back button to navigate back to the Record Workout screen.

The user can turn off the screen of Android phone or launch other applications after a workout session has started (after the user clicked on the Start Workout button). In order to keep recording the workout data, i hvae used a Remote Service that is in a different process from that of the activities. At the appropriate time, each workout session data will be saved to SQLite database on the phone using Content Provider.

Besides the step counts, you’ll take advantage of the build-in GPS feature on Android phone to show the path of user’s workout session. Android provides a set of Google Map APIs for Android as well as very good information on how to integrate Google Map and navigation into your app. You’ll find more information here: https://developers.google.com/maps/documentation/android-api/start.

Both Calories and distance can be estimated from the step counts. You can make reasonable assumption for both calories burnt and the stride length for each step. This article shows you a chart that converts calories burned walking from step count and the user’s weight:

You can also find the distance from steps:

For plotting real-time data for Calories and steps per 5 minutes for the Workout Details screen, I have used MPAndroidChart:

in my program. The link takes you to the official web site for MPAndroidChart on Github.com. You will find documentation as well as good examples on the website.
