使用angularjs和离子在phonegap上运行后台进程的访问

Question

我在使用angularjs和离子的phonegap项目中的地理位置后台进程（https://github.com/christocracy/cordova-plugin-background-geolocation）存在问题。这个过程运行良好，但有时我无法阻止它。
如果应用程序在前台运行，它都可以正常工作。但是当我启动后台服务，然后按下我的设备上的主页按钮（samsung galaxy s2）时，该过程在后台运行 - >正确。现在我重新打开应用程序并尝试停止后台进程，但目前它不起作用。

看来我没有正确的过程实例。

这是我的代码：

var bgGeo; 

angular.module('starter.services', []) 
.factory('LocationService', function($http, $location){ 
    function startBackgroundLocation() { 
     var gpsOptions = { 
      enableHighAccuracy : true, 
      timeout: 10000, 
      maximumAge: 5000 
     }; 
     navigator.geolocation.getCurrentPosition(function(location) { 
      console.log('Location from Phonegap'); 
     }, 
     function (error){ 
      alert('error with GPS: error.code: ' + error.code + ' Message: ' + error.message); 
     },gpsOptions); 


     bgGeo = window.plugins.backgroundGeoLocation; 

     /** 
     * This would be your own callback for Ajax-requests after POSTing background geolocation to your server. 
     */ 
     var yourAjaxCallback = function(response) { 
      //// 
      // IMPORTANT: You must execute the #finish method here to inform the native plugin that you're finished, 
      // and the background-task may be completed. You must do this regardless if your HTTP request is successful or not. 
      // IF YOU DON'T, ios will CRASH YOUR APP for spending too much time in the background. 
      // 
      // 
      bgGeo.finish(); 
     }; 

     /** 
     * This callback will be executed every time a geolocation is recorded in the background. 
     */ 
     var callbackFn = function(location) { 
      alert('[js] BackgroundGeoLocation callback: ' + location.latitudue + ',' + location.longitude); 
      // Do your HTTP request here to POST location to your server. 
      // 
      // 

      // This is never called in Android 
      yourAjaxCallback.call(this); 
     }; 

     var failureFn = function(error) { 
      alert('BackgroundGeoLocation error'); 
     } 

     // BackgroundGeoLocation is highly configurable. 
     bgGeo.configure(callbackFn, failureFn, { 
      url: apiUrl + '/position/', // <-- only required for Android; ios allows javascript callbacks for your http 
      params: {            // HTTP POST params sent to your server when persisting locations. 
       auth_token: localStorage.getItem('gcmToken') 
      }, 
      desiredAccuracy: 10, 
      stationaryRadius: 20, 
      distanceFilter: 30, 
      debug: true // <-- enable this hear sounds for background-geolocation life-cycle. 
     }); 

     // Turn ON the background-geolocation system. The user will be tracked whenever they suspend the app. 
     // wenn der Service bereits läuft, nicht mehr starten 
     bgGeo.start(); 
    } 

    function stopBackgroundLocation(){ 
     bgGeo.stop(); 
    } 

    return { 
     start: function(){ 
      init(); 
     }, 
     stop : function() { 
      stopBackgroundLocation(); 
     } 
    } 
} 

当我打电话LocationService.stop（）应用程序恢复使用后，后台地理位置不会停止。

有人知道最新错误或我必须添加什么？谢谢。

@Aleks：也许你知道一个解决方案？

我现在使用此功能：

function stopService(){ 
    var bgGeoService = window.plugins.backgroundGeoLocation 
    bgGeoService.stop() 
} 

它似乎工作。 但有另一种方法，看到这个链接：https://github.com/christocracy/cordova-plugin-background-geolocation/issues/48

希望这会有所帮助。
