    // Check condition device location is open or close.
    if( DevicesLocation === 'close' ) {
       alert('App need to run your location, please open your devices location');
       // other process 
    } else {
       navigator.geolocation.getCurrentPosition(
          (position) =&gt; {
             var initialPosition = JSON.stringify(position);
             this.setState({ initialPosition});
          },
          (error) =&gt; console.log(error.message)
