public geolocate() {
      let options = {
        enableHighAccuracy: true
      };
      console.log('in');
      
      this.locac.canRequest().then((res: boolean) => {
        if (res) {
          console.log('res'+res);

          this.locac.request(this.locac.REQUEST_PRIORITY_HIGH_ACCURACY).then(() => {
            this.geolocation.getCurrentPosition(options).then((position: Geoposition) => {
              console.log(position);
            }).catch((err) => {
              console.log('err'+JSON.stringify(err));
            })
          }, (error) => {
            console.log('err'+JSON.stringify(error));
