Project 3: Recognizing Activities with Android Sensors, (8/100 of course grade)
CS 528 Fall 2018 Semester
Due date: Friday, October 25, by class time

Overview

The aim of this project is to get you familiar with Android Sensors, specifically the activity recognition API. You will also explore GeoFences and Android Maps. You should do the project in your groups of 5 students.

Project Preparation

Step 1: Review Slides for Lectures 4 - 5

Step 2: Review the following information on Activity Recognition

Google recently deprecated thecActivity Recognition API. Android now uses a NEW Activity Recognition Client. Please use the new AR client instead. Information about the new AR client is at:

https://developers.google.com/android/reference/com/google/android/gms/location/ActivityRecognitionClient

Make sure you fully understand how services and broadcasts work in Android before trying to use the Activity Recognition Client. The recognition code above is used in the BackgroundDetectedActivitiesService class. To be specific, the following is the only code in the class you need for registering for activity detection.

Task task = mActivityRecognitionClient.requestActivityUpdates(
                Constants.DETECTION_INTERVAL_IN_MILLISECONDS,
                mPendingIntent);
 
        task.addOnSuccessListener(new OnSuccessListener() {
            @Override
            public void onSuccess(Void result) {
                Toast.makeText(getApplicationContext(),
                        "Successfully requested activity updates",
                        Toast.LENGTH_SHORT)
                        .show();
            }
        });
 
        task.addOnFailureListener(new OnFailureListener() {
            @Override
            public void onFailure(@NonNull Exception e) {
                Toast.makeText(getApplicationContext(),
                        "Requesting activity updates failed to start",
                        Toast.LENGTH_SHORT)
                        .show();
            }
        });
}

To assist you, I got a student of mine to create a code example using the new Android Activity Recognition Client API and put it up on gitHub. Please feel free to use his code for your work.

Step 3: Get Activity Recognition Working

Step 4: Get GeoFencing Working

• [ Tutplus Tutorial: How to work with GeoFences on Android by Tin Megali ]

Step 5: Implement step counting

Project Requirements

You are to develop an app that continously recognizes 3 of the user's activities (walking, running, and still). Whenever an activity is recognized, an appropriate picture is displayed and text describing the activity is displayed as well. Display the following images corresponding to the activities:

[ Running ]
[ Still ]
[ Walking ]

Whenever a user switches to a new activity, a toast pops up displaying how long the last activity lasted. For instance, if the user was walking and became still, a toast may pop up announcing "You have just walked for 1 min, 36 seconds".

Set up 2 GeoFences at the following locations:

• At the front door of fuller labs
• At the Front of the Gordon Library
