Obtenga la actividad actual del usuario utilizando la API de instantáneas

Para solicitudes no constantes de una sola vez para la actividad física de un usuario, use la API de instantáneas:

// Remember to initialize your client as described in the Remarks section
Awareness.SnapshotApi.getDetectedActivity(client)
    .setResultCallback(new ResultCallback<DetectedActivityResult>() {
        @Override
        public void onResult(@NonNull DetectedActivityResult detectedActivityResult) {
            if (!detectedActivityResult.getStatus().isSuccess()) {
                Log.e(getClass().getSimpleName(), "Could not get the current activity.");
                return;
            }
            ActivityRecognitionResult result = detectedActivityResult
                .getActivityRecognitionResult();
            DetectedActivity probableActivity = result.getMostProbableActivity();
            Log.i(getClass().getSimpleName(), "Activity received : " + 
                probableActivity.toString());
        }
    });

Obtener el estado de los auriculares con la API de instantáneas

// Remember to initialize your client as described in the Remarks section
Awareness.SnapshotApi.getHeadphoneState(client)
    .setResultCallback(new ResultCallback<HeadphoneStateResult>() {
        @Override
        public void onResult(@NonNull HeadphoneStateResult headphoneStateResult) {
            Log.i(TAG, "Headphone state connection state: " + 
                headphoneStateResult.getHeadphoneState()
                .getState() == HeadphoneState.PLUGGED_IN));
        }
    });

Obtener ubicación actual utilizando API de instantáneas

// Remember to intialize your client as described in the Remarks section
Awareness.SnapshotApi.getLocation(client)
    .setResultCallback(new ResultCallback<LocationResult>() {
        @Override
        public void onResult(@NonNull LocationResult locationResult) {
            Location location = locationResult.getLocation();
            Log.i(getClass().getSimpleName(), "Coordinates: "location.getLatitude() + "," + 
                location.getLongitude() + ", radius : " + location.getAccuracy());
        }
    });

Obtener lugares cercanos utilizando API de instantáneas

// Remember to initialize your client as described in the Remarks section 
Awareness.SnapshotApi.getPlaces(client)
    .setResultCallback(new ResultCallback<PlacesResult>() {
        @Override
        public void onResult(@NonNull PlacesResult placesResult) {
            List<PlaceLikelihood> likelihoodList = placesResult.getPlaceLikelihoods();
            if (likelihoodList == null || likelihoodList.isEmpty()) {
                Log.e(getClass().getSimpleName(), "No likely places");
            }
        }
    });

En cuanto a obtener los datos en esos lugares, aquí hay algunas opciones:

Place place = placeLikelihood.getPlace();
String likelihood = placeLikelihood.getLikelihood();
Place place = likelihood.getPlace();
String placeName = place.getName();
String placeAddress = place.getAddress();
String placeCoords = place.getLatLng();
String locale = extractFromLocale(place.getLocale()));

Obtener el clima actual utilizando API de instantáneas

// Remember to initialize your client as described in the Remarks section
Awareness.SnapshotApi.getWeather(client)
    .setResultCallback(new ResultCallback<WeatherResult>() {
        @Override
        public void onResult(@NonNull WeatherResult weatherResult) {
            Weather weather = weatherResult.getWeather();
            if (weather == null) {
                Log.e(getClass().getSimpleName(), "No weather received");
            } else {
                Log.i(getClass().getSimpleName(), "Temperature is " +
                        weather.getTemperature(Weather.CELSIUS) + ", feels like " +
                        weather.getFeelsLikeTemperature(Weather.CELSIUS) + 
                        ", humidity is " + weather.getHumidity());
            }
        }
    });

Obtén cambios en la actividad del usuario con Fence API

Si desea detectar cuándo su usuario comienza o finaliza una actividad como caminar, correr o cualquier otra actividad de la clase DetectedActivityFence , puede crear una cerca para la actividad que desea detectar y recibir una notificación cuando su usuario comience / Termina esta actividad. Al utilizar un BroadcastReceiver , obtendrá un Intent con datos que contienen la actividad:

// Your own action filter, like the ones used in the Manifest.
private static final String FENCE_RECEIVER_ACTION = BuildConfig.APPLICATION_ID +
    "FENCE_RECEIVER_ACTION";
private static final String FENCE_KEY = "walkingFenceKey";
private FenceReceiver mFenceReceiver;
private PendingIntent mPendingIntent;

// Make sure to initialize your client as described in the Remarks section.
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    // etc.

    // The 0 is a standard Activity request code that can be changed to your needs.
    mPendingIntent = PendingIntent.getBroadcast(this, 0, 
        new Intent(FENCE_RECEIVER_ACTION), 0);
    registerReceiver(mFenceReceiver, new IntentFilter(FENCE_RECEIVER_ACTION));

    // Create the fence.
    AwarenessFence fence = DetectedActivityFence.during(DetectedActivityFence.WALKING);
    // Register the fence to receive callbacks.
    Awareness.FenceApi.updateFences(client, new FenceUpdateRequest.Builder()
        .addFence(FENCE_KEY, fence, mPendingIntent)
        .build())
        .setResultCallback(new ResultCallback<Status>() {
            @Override
            public void onResult(@NonNull Status status) {
                if (status.isSuccess()) {
                    Log.i(FENCE_KEY, "Successfully registered.");
                } else {
                    Log.e(FENCE_KEY, "Could not be registered: " + status);
                }
            }
        });
    }
}

Ahora puede recibir la intención con un BroadcastReceiver para obtener devoluciones de llamada cuando el usuario cambia la actividad:

public class FenceReceiver extends BroadcastReceiver {

    private static final String TAG = "FenceReceiver";

    @Override
    public void onReceive(Context context, Intent intent) {
        // Get the fence state
        FenceState fenceState = FenceState.extract(intent);

        switch (fenceState.getCurrentState()) {
            case FenceState.TRUE:
                Log.i(TAG, "User is walking");
                break;
            case FenceState.FALSE:
                Log.i(TAG, "User is not walking");
                break;
            case FenceState.UNKNOWN:
                Log.i(TAG, "User is doing something unknown");
                break;
        }
    }
}

Obtenga cambios para la ubicación dentro de un cierto rango usando la API de Fence

Si desea detectar cuándo su usuario ingresa a una ubicación específica, puede crear una cerca para la ubicación específica con el radio que desee y recibir una notificación cuando su usuario ingrese o salga de la ubicación.

// Your own action filter, like the ones used in the Manifest
private static final String FENCE_RECEIVER_ACTION = BuildConfig.APPLICATION_ID +
    "FENCE_RECEIVER_ACTION";
private static final String FENCE_KEY = "locationFenceKey";
private FenceReceiver mFenceReceiver;
private PendingIntent mPendingIntent;

// Make sure to initialize your client as described in the Remarks section
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    // etc

    // The 0 is a standard Activity request code that can be changed for your needs
    mPendingIntent = PendingIntent.getBroadcast(this, 0, 
        new Intent(FENCE_RECEIVER_ACTION), 0);
    registerReceiver(mFenceReceiver, new IntentFilter(FENCE_RECEIVER_ACTION));

    // Create the fence
    AwarenessFence fence = LocationFence.entering(48.136334, 11.581660, 25);
    // Register the fence to receive callbacks.
    Awareness.FenceApi.updateFences(client, new FenceUpdateRequest.Builder()
        .addFence(FENCE_KEY, fence, mPendingIntent)
        .build())
        .setResultCallback(new ResultCallback<Status>() {
            @Override
            public void onResult(@NonNull Status status) {
                if (status.isSuccess()) {
                    Log.i(FENCE_KEY, "Successfully registered.");
                } else {
                    Log.e(FENCE_KEY, "Could not be registered: " + status);
                }
            }
        });
    }
}

Ahora cree un BroadcastReciver para recibir actualizaciones en el estado del usuario:

public class FenceReceiver extends BroadcastReceiver {

    private static final String TAG = "FenceReceiver";

    @Override
    public void onReceive(Context context, Intent intent) {
        // Get the fence state
        FenceState fenceState = FenceState.extract(intent);

        switch (fenceState.getCurrentState()) {
            case FenceState.TRUE:
                Log.i(TAG, "User is in location");
                break;
            case FenceState.FALSE:
                Log.i(TAG, "User is not in location");
                break;
            case FenceState.UNKNOWN:
                Log.i(TAG, "User is doing something unknown");
                break;
        }
    }
}
