physical information about the phone

screen resolution?

where is the phone?

is the phone moving?

can I alert the user?

screen orientation?

where is the phone?

GeoCoordinateWatcher watcher = new GeoCoordinateWatcher(GeoPositionAccuracy.Low); // saves power watcher.MovementThreshold = 20; // minimum of 20m - avoids noise, saves power watcher.StatusChanged += (sender, args) => { if (args.Status == GeoPositionStatus.Ready) { // ready... } }; watcher.PositionChanged += (sender, args) => { double altitude = args.Position.Location.Altitude; double latitude = args.Position.Location.Latitude; double longitude = args.Position.Location.Longitude; }; watcher.Start(); // this can throw and we should call Stop()

System.Device.Location.dll

where is that again?

CivicAddressResolver resolver = new CivicAddressResolver(); GeoCoordinate location = GetAlreadyDeterminedLocation(); resolver.ResolveAddressCompleted += (sender, args) => { if (args.Error == null) { string line1 = args.Address.AddressLine1; string line2 = args.Address.AddressLine2; string city = args.Address.City; // etc... } }; resolver.ResolveAddressAsync(location); System.Device.Location.dll

is the phone moving? can I alert the user?

AccelerometerSensor.Default.ReadingChanged += (sender, args) => { if (args.Value.State == SensorState.Ready) { // Deltas X,Y,Z from -1 to +1 – should also check timestamp here if (args.Value.Value.Y >= -0.5) { // Help! I'm falling! Not sure this will help but... VibrateController.Default.Start(new TimeSpan(0, 0, 2)); } } }; // this could throw & we should stop it at some point AccelerometerSensor.Default.Start();
