In fallowing code I’m trying to access new geolocation of current device and speed of motion but I don’t know am i did it right or no, the output is attached also bellow Ho much is my speed?
@Component({
selector: 'page-page1',
templateUrl: 'page1.html'
})
export class Page1 {
public lat;
public lng;
public speed;
public watch: any;
constructor(public navCtrl: NavController, public Geolocation: Geolocation, public zone: NgZone,
public backgroundGeolocation: BackgroundGeolocation,
private deviceMotion: DeviceMotion
) {
this.startTracking();
}
startTracking() {
this.deviceMotion.getCurrentAcceleration().then(
(acceleration: DeviceMotionAccelerationData) => console.log(acceleration),
(error: any) => console.log(error)
);
var subscription = this.deviceMotion.watchAcceleration().subscribe((acceleration: DeviceMotionAccelerationData) => {
console.log(acceleration);
});
let config = {
desiredAccuracy: 0,
stationaryRadius: 20,
distanceFilter: 10,
debug: true,
interval: 2000
};
this.backgroundGeolocation.configure(config).subscribe((location) => {
console.log('BackgroundGeolocation: ' + location.latitude + ',' + location.longitude);
this.zone.run(() => {
this.lat = location.latitude;
this.lng = location.longitude;
this.speed = location.speed;
});
}, (err) => {
console.log(err);
});
this.backgroundGeolocation.start();
let options = {
frequency: 3000,
enableHighAccuracy: true
};
this.watch = this.Geolocation.watchPosition(options).filter((p: any) => p.code === undefined).subscribe((position: Geoposition) => {
console.log(position);
this.zone.run(() => {
this.lat = position.coords.latitude;
this.lng = position.coords.longitude;
});
});
}
stopTracking() {
console.log('stopTracking');
this.backgroundGeolocation.finish();
this.watch.unsubscribe();
}
}
