   > it only shows the option to allow get location while use, instead of always, is there a way to get this permission to always,
   
   I'm not sure how you are accessing geolocation from the background as this plugin doesn't really support this due to limitations.
   
   On Android, we don't have a geolocation implemented, we just use the browser implementation. The plugin is purely to manage permissions. This is problematic for background usage as apps in the background has no activity and the webview cannot exists outside of an Activity. For iOS, the webview is completely paused while the app is in the background. So it cannot receive GPS events during in the background.
   
   If you need background support, a third-party plugin will be required that sets up the proper background services and provides the ability to send updates to the webview when the webview is capable of handling those updates (ie when it comes into the foreground).
   
   > Also, when I am using watchposition I get an empty array and cant access the coords,
   
   This plugin doesn't pass arrays for coordinates. It passes an object with the following properties:
   
   ```javascript
   var onSuccess = function(position) {
           alert('Latitude: '          + position.coords.latitude          + '\n' +
                 'Longitude: '         + position.coords.longitude         + '\n' +
                 'Altitude: '          + position.coords.altitude          + '\n' +
                 'Accuracy: '          + position.coords.accuracy          + '\n' +
                 'Altitude Accuracy: ' + position.coords.altitudeAccuracy  + '\n' +
                 'Heading: '           + position.coords.heading           + '\n' +
                 'Speed: '             + position.coords.speed             + '\n' +
                 'Timestamp: '         + position.timestamp                + '\n');
       };
   ```
