The way this was setup previously, if an error occurred on the watchPosition observable, the observer was sent an error, which would have to be caught. This also has the side effect of completing the observable, which means anything down stream that would be subscribed would be unsubscribed and no longer receive updates. Instead of using binding the error callback to ```observer.error``` this change just binds the error callback to ```observer.next``` and lets the subscriber filter out results that match ```PositionError``` rather than having to manage re-subscribing (which could just immediately fail and enter a loop of catch/retry) |

Ionic Native
Ionic Native is a curated set of wrappers for Cordova plugins that make adding any native functionality you need to your Ionic, Cordova, or Web View mobile app easy.
Documentation
For the full Ionic Native documentation, please visit http://ionicframework.com/docs/v2/native/.
Promises and Observables
Ionic Native wraps plugin callbacks in a Promise or Observable, providing a common interface for all plugins and ensuring that native events trigger change detection in Angular 2.
import { Geolocation } from 'ionic-native';
Geolocation.getCurrentPosition().then(pos => {
console.log('lat: ' + pos.coords.latitude + ', lon: ' + pos.coords.longitude);
});
let watch = Geolocation.watchPosition().subscribe(pos => {
console.log('lat: ' + pos.coords.latitude + ', lon: ' + pos.coords.longitude);
});
// to stop watching
watch.unsubscribe();
Angular 1
Ionic Native works as a stand-in for ngCordova. In many cases, the usage is identical, but we import ionic.native instead of ngCordova as our module.
As a rule of thumb: take the ES6 class name of the plugin and add $cordova to get the service name. For example, Geolocation would be $cordovaGeolocation, and Camera will be $cordovaCamera:
angular.module('myApp', ['ionic', 'ionic.native'])
.controller('MyCtrl', function($scope, $cordovaCamera) {
$scope.takePicture = function() {
$cordovaCamera.getPicture(opts).then(function(p) {
}, function(err) {
});
};
});
For services that return observables, the Angular 1 digest cycle must be done manually (currently):
angular.module('myApp', ['ionic', 'ionic.native'])
.controller('MyCtrl', function($scope, $cordovaGeolocation) {
$scope.takePicture = function() {
$cordovaGeolocation.watchPosition(opts).subscribe(function(p) {
$scope.$apply(function() {
$scope.position = p.coords;
});
}, function(err) {
});
};
});
Runtime Diagnostics
Spent way too long diagnosing an issue only to realize a plugin wasn't firing or installed? Ionic Native lets you know what the issue is and how you can resolve it.
Installation
Run following commmand to install ionic-native in your project.
npm install ionic-native --save
Plugin Missing?
Let us know or submit a PR! Take a look at the Developer Guide for more on how to contribute. ❤️
