【问题描述】:
应用的目标:在每次移动时获取地理位置并在应用处于前台和后台时记录位置。
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”从未被触发。
我正在使用 xcode 在 IOS 上进行测试 > 功能音频和位置已为后台活动激活。我还制作了插件中给出的 jQuery 示例示例,因此我看到它可以正常工作,但从未使用 ionic/angularjs。
这是当前处理背景的控制器:
.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
})
我已将所有代码(一个完整的 ionic 应用程序启动器)放在 github 上:https://github.com/Jeff86/ionic_ngcordova_backgroundgeo_test/tree/master
