应用程序的目标:当应用程序处于前台和后台时,在每次移动时获取地理位置并记录位置。

我已经尝试了很多代码和组合,但我无法让它工作(从现在起 2 天......)。

经典的地理定位 (getCurrentPosition) 工作正常,但是当我们关闭应用程序时,后台地理定位已启动,但没有任何反应……函数“callbackFn”永远不会被触发。

我正在 IOS 上测试 xcode > Capabilities Audio & location 为后台活动激活。我还制作了插件中给出的 jQuery 示例示例,所以我看到它可以工作,但从来没有使用 ionic/angularjs。

这是处理背景的当前控制器:

.controller('TestCtrl', function($scope, $timeout, $cordovaBackgroundGeolocation, $ionicPlatform, $window)
{
$scope.lat_geo = "loading lat...";
$scope.long_geo = "loading long...";


//-- Geolocal launch
var options = {
    enableHighAccuracy : false,
    desiredAccuracy: 0,
    stationaryRadius: 1,
    distanceFilter: 5,
    notificationTitle: 'Background tracking', // <-- android only, customize the title of the notification
    notificationText: 'ENABLED', // <-- android only, customize the text of the notification
    activityType: 'AutomotiveNavigation',
    debug: true, // <-- enable this hear sounds for background-geolocation life-cycle.
    stopOnTerminate: false // <-- enable this to clear background location settings when the app terminates
};

$ionicPlatform.ready(function()
{
    console.log("[IONIC PLATFORM IS NOW READY]");

    //-- First launch a basic geolocalisation to get user acceptance of geosharing ;)
    navigator.geolocation.getCurrentPosition(function(location) {
            console.log('[GEOLOCAL JS1] Location from Phonegap');
    },
    function (error){
            console.log('[GEOLOCAL JS1] error with GPS: error.code: ' + error.code + ' Message: ' + error.message);
    },options);

    //-- test adaptation depuis l'app jquery
    var callbackFn = function(location) {
            console.log('[BackgroundGeoLocation] Update callback:  ' + location.latitude + ',' + location.longitude);
    };

    var failureFn = function(error) {
            console.log('[BackgroundGeoLocation] Error: '+error);
    };

    $cordovaBackgroundGeolocation.configure(callbackFn, failureFn, options);

    // Turn ON the background-geolocation system.  The user will be tracked whenever they suspend the app.
    $cordovaBackgroundGeolocation.start();

    //-- Just a timeout to retreive long / lat
    $timeout(function()
    {
        navigator.geolocation.getCurrentPosition(function(location)
        {
            console.log('[GEOLOCAL JS3] Location from Phonegap');
            startPos = location;
            $scope.$apply(function () {
                $scope.lat_geo = startPos.coords.latitude;
                $scope.long_geo = startPos.coords.longitude;
            });
            console.log("[GEOLOCAL BASIC] OK this time :)");
        },
        function (error){
            console.log('[GEOLOCAL JS3] error with GPS: error.code: ' + error.code + ' Message: ' + error.message);
        },options);
    }, 3000);

});
//-- End Geolocal
})

我已经把我所有的代码(一个完整的离子应用程序启动器)放在 github 上:https ://github.com/Jeff86/ionic_ngcordova_backgroundgeo_test/tree/master

我读了这篇文章http://ngcordova.com/docs/plugins/backgroundGeolocation/

我看到您应该将代码放入

document.addEventListener("deviceready", function () { ... });

你有什么解决办法吗?

您绝对不想在 bg 中使用 std Cordova-geolocation 插件,它会立即耗尽电池。

我是 Ionic 底层背景地理定位插件的作者。我创建了一个新的基于离子的 SampleApp。
