Goal of the app: get geolocation on each move and log location either when app is in foreground and background.
I've tried so many code and combination but I can't manage to have it working (2 days from now...).
The classic geolocation (getCurrentPosition) is working fine but when we close the app the background geolocation is launched but nothing happen... Function "callbackFn" is never fired.
I'm testing on IOS with xcode > Capabilities Audio & location activated for background activity. I also made working the jQuery sample example given in plugin so I saw it working but never with ionic/angularjs.
Here is the current controller handling the background:
.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
})
I've put all my code (a complete ionic app starter) on github: https://github.com/Jeff86/ionic_ngcordova_backgroundgeo_test/tree/master
I read this article http://ngcordova.com/docs/plugins/backgroundGeolocation/
I see that you should put your code into
document.addEventListener("deviceready", function () { ... });
Do you find any solution?
You definitely don't want to use the std Cordova-geolocation plugin in the bg, it'll kill the battery in no time.
I'm the author of the underlying background-geolocation plugin for Ionic. I've created a New Ionic-based SampleApp.

Context:
Hello, I am working on a Ionic application (made in Typescript). In this application, I control a wifi camera via HTTP Request to the IP (http://192.72.1.1/myCommand to be precise).
Main actions I do with the camera:
Start recording
Stop recording
Get videos list
Download a video
When I use the Ionic DevApp:
With the Ionic DevApp, everything works perfectly, I can do all mains actions without a problem.
When I compile the application on IOS:
I compile with the command ionic cordova build ios --prod, then I archive with Xcode and send it to the AppStore to test it with Test Flight.
I got no errors while compiling / archive the application. But when I try it on my iPhone, I can start / stop recording, but can't download the video.
Problem:
Some commands are not working, but I don't know if it is getting the list or downloading the video, I have no logs. I don't understand why some commands are working but others no.
IOS is blocking download requests? How to solve my problem?
Notes:
I already tried all basic things like delete the IOS platform, recompile, uninstall, ...
I tried different Ionic HTTP plugins, same problem with all of them.
Some code:
Start / Stop the camera: (it is the same command to start / stop).
startCamera(){
var url = "http://192.72.1.1/changeRecordStatus";
var result = this.http.get(url);
result.subscribe(data => {
console.log("Works");
},
err => {
console.log("Error" + err);
}
);
}
Getting the name of the last video:
getLastVideo(){
var url = "http://192.72.1.1/listVideos";
this.http.get(url, {}, {})
.then(data => {
var xml = data.data
var xmlDOM = new DOMParser().parseFromString(xml, 'text/xml');
var temp = this.xmlToJson(xmlDOM); // function that convert XML to JSON
var resultArray = Object.keys(temp).map(function(i){
let ite = temp[i];
return ite;
});
resultArray = resultArray[0]['file'].reverse();
this.lastVideo = resultArray[0]['name']; // lastVideo is a global variable
},
(error) =>{
console.log("Error while getting the name of the last video" + error);
});
}
Downloading the file from the camera:
downloadFileFromCamera() {
this.getLastVideo();
var basename_file = this.lastVideo;
var url = "http://192.72.1.1" + basename_file;
this.fileTransfer.download(encodeURI(url), this.file.dataDirectory + '/videos/' + basename_file, true).then((entry) => {
this.video[this.counterVideos] = entry; // video is a global array
this.counterVideos +=1;
}, (error) => {
console.log("Error while downloading the last video" + error);
});
}
If someone knows how to solve my problem, I would be so grateful! Thanks in advance.
I am currently using, IONIC v1.0.0, AngularJs and ngCordova v0.1.23-alpha on IOS and Android.
I have come across an issue with my login view freezing up.
It happens after opening InAppBrowser and hitting "back to app" (close button caption used for IOS to get back) is freezes my login view disabling the ability to touch on the whole screen and making me unable to login. It only happens if I call InAppBrowser when starting the app, if I use it during the app life cycle (after login in), it doesn't do it.
Here are some of my code pieces
In app.js:
angular.module('MyApp', ['ionic', 'MyApp', 'ngCordova', 'mainController', 'loginController', 'pascalprecht.translate', 'ngStorage', 'ngSanitize', 'ngAnimate', 'ngTouch', 'ngCookies', 'ngLocale', 'testController'])
In mainController I have Factory:
.factory('customMainFunction', function ($rootScope, $ionicLoading, $ionicScrollDelegate, $ionicPopup,
$timeout, $localStorage, $location, $ionicHistory, $window, $cordovaInAppBrowser) {
var Token = "";
return {
openBrowser: function (link) {
var options = {
location: 'yes',
clearcache: 'yes',
toolbar: 'yes',
closebuttoncaption: 'Back to App'
};
document.addEventListener("deviceready", function () {
$cordovaInAppBrowser.open(link, '_blank', options)
.then(function (event) {
// success
})
.catch(function (event) {
// error
});
}, false);
$rootScope.$on('$cordovaInAppBrowser:loadstart', function (e, event) {
//console.log(event);
var url = "";
var positionNumber;
var res;
url = event.url;
positionNumber = url.search("ssoToken=");
res = url.substr(Number(positionNumber)+9);
/*positionNumber = url.search("module=");
res = url.substr(Number(positionNumber)+6);*/
if(url !== "" && positionNumber >= 0 && res.length > 0) {
$rootScope.$broadcast('ssoToken', { token: res });
$cordovaInAppBrowser.close();
}
});
$rootScope.$on('$cordovaInAppBrowser:loadstop', function (e, event) {
console.log("loadstop");
//console.log(event);
// insert CSS via code / file
//$cordovaInAppBrowser.insertCSS({
// code: ''
//});
// insert Javascript via code / file
//$cordovaInAppBrowser.executeScript({
// file: ''
//});
});
$rootScope.$on('$cordovaInAppBrowser:loaderror', function (e, event) {
});
$rootScope.$on('$cordovaInAppBrowser:exit', function (e, event) {
});
}
}
})
If anybody has encounter such issue please let me know what can be done to resolve it. Any question or clarifications let me know. Thanks in advance.
Found the issue of my own problem. Basically the problem is related to Threading. Look for Threading. How did I find out about it? On XCode I was able to see a message saying:
THREAD WARNING: ['InAppBrowser'] took '108.12' ms. Plugin should use a
background thread
There are two ways to solve this (I believe):
1- Using background threading (just like the message states). Please refer to:
How to run cordova plugins in the background?
2- Wrap the openBrowser function call (in my case) in a setTimeout. That will delay the call until the thread is done and UI won't be blocked. Once done (in my case) it opened the inAppBrowser and when I hit "Back to app" UI was not block at all.
Hope this helps someone out there.
I am building a food delivery app using Ionic. And I am having problems getting the app to work on mobile for the address creation step. After creating an account the user must create a delivery address, at which point the app figures out what delivery location to use.
Address creation works in Chrome (ionic serve) and in iOS simulator (ionic run ios -l -c -s).
However, once I've uploaded the app to my Ionic View iOS app for testing, it gets stuck at the Address creation step.
But at the address creation step, the Ionic loading wheel starts but it doesn't go away and there is no state transition to the menu.
Here is the implementation in the controller.
Address.create($scope.newAddress, $scope.user)
.then(function(response) { // never gets a response back in Ionic View
console.log("address created");
user.save(null,
{ success: function(user) {
// success callback
}, error: function(error) {
// throw error
}
});
}, function(error) {
// throw error
});
The Address.create() method I have implemented is fairly lengthy:
...
.factory('Address', ['$http', '$q', 'PARSE_HEADERS'
function ($http, $q, PARSE_HEADERS) {
return {
create: function(data, userID) {
var deferred = $q.defer();
var zipArray = ['1111','22222','33333'];
var inZone = false;
var restaurantCoords = {
latitude: 11.11111, longitude: 22.22222
};
for (var i=0, bLen=zipBrooklyn.length; i<bLen; i++) {
if(data.zipCode==zipArray[i]) {
inZone = true;
}
}
if (inZone == true ) { // valid zip
function onSuccess(coords) {
var limit = 3041.66;
var meters = getDistance(coords, restaurantCoords);
if (meters < limit) {
$http.post('https://api.parse.com/1/classes/Address', data, {
headers: PARSE_HEADERS
})
.success(function(addressData) {
deferred.resolve(addressData);
})
.error(function(error, addressData) {
deferred.reject(error);
});
}
function onError() {
deferred.reject("Unable to Geocode the coordinates");
}
// GET COORDS
navigator.geocoder.geocodeString(onSuccess, onError, data.address1 + ',' + data.zipCode);
}
}
return deferred.promise;
}]);
I've stripped out all of the code that I believe was working.
So a valid answer for this question could take multiple forms:
I'd accept an answer giving a decent way to debug apps IN Ionic View.
Or, if someone could provide an answer as to why it might be working in the browser and in iOS Simulator, but not iOS itself, that would be appreciated even more.
Ionic view doesn't support all the plugins yet. please take a look at this link for the list of supported plugins.
Device is always better (First Option). If you have a ios device and apple developer account. You can create and configure the required certificate with the device id and run the app using 'ionic run ios'. Second option is iOS simulator. You can use the simulator for your whole app, though few tasks would need a device.
Even if you use the simulator for the whole development, it is always advisable to test in the device before launcing the app.
I have spent lot of time to find correct cordova plugin for parse push notifications for both Android & iOS platforms.
My requirements are:
To receive parse push notification (in both android & iOS)
Able to store all the incoming push notifications in mobile local storage Sqlite.
I have tried all the below parse push cordova plugins for both Android & iOS platforms.
https://github.com/avivais/phonegap-parse-plugin
https://github.com/taivo/parse-push-plugin
https://github.com/campers/parse-push-plugin
https://github.com/manishiitg/parse-push-plugin
For Android: All the above plugins are working perfectly to fulfill my above mentioned requirements.
For iOS: Only 1st plugin i.e https://github.com/avivais/phonegap-parse-plugin is working. And that too i was not able to save the notifications in local storage sqlite. That means only my 1st requirement is fulfilled but not my 2nd requirement.
All the github pages of remaining plugins (i.e 2nd, 3rd, 4th) states that:
"Please note that I've only worked on the Android aspect of this fork. The iOS side is not yet up to date."
Is there any plugin which will work for both Android & iOS platforms to fulfill my 2 requirements?
(or)
If there is no common plugin for both the platforms, then how can I store the incoming plugins in iOS sqlite?
Please help me. Thanks in advance.
I happen to maintain https://github.com/taivo/parse-push-plugin
It looks like you caught my fork at its infancy. I picked it up when the upstream fork seemed stagnant for a while and at that time I was only addressing the Android aspect. Since then I've provided full iOS support. And it works for parse-server as well as the out-going parse.com. I also did one better and made installation just a matter of
cordova add https://github.com/taivo/parse-push-plugin
and writing a few config.xml tags to indicate server url, and app id.
That should take out the big pain of manually messing with Android Manifest, Java, and Objective C when setting up the plugin.
It should now meet or exceed your requirement. To receive push notification and store in sqlite, all you have to do is set an event handler in javascript. Be sure to wrap it with some sort of device ready or platform ready event handler to ensure the plugin has properly loaded.
$ionicPlatform.ready(function(){
if(window.ParsePushPlugin){
ParsePushPlugin.on('receivePN', function(pn){
console.log('yo i got this notif:' + JSON.stringify(pn) );
//
// do your sqlite storage here
//
});
}
});
You just might be interested in the Azure Push Notifications. It combines both Push notification services so you can send messages to both devices from one central point.
I quote:
Notification Hubs A scalable, cross-platform solution for sending push
notifications to mobile devices, Notification Hubs works well with
Cordova apps. Notification Hubs manages the registrations with each
PNS. More important, Notification Hubs lets you create template
registrations so you can send messages to all registered devices,
regardless of platform, with only a single line of code. You can also
use tags to send targeted notifications only to devices with specific
registrations. For more information about Notification Hubs, see the
Azure Web site at aka.ms/nkn4n4.
Here i have a helper class for registering your device with the pushnotification service. For sending push notifications, you can use an azure portal and send styled push notifications in json format.

Then you just need to initialize the plugin when the application starts:
//azure notificationshub connection information
notificationHubPath = "notificationhub name";
connectionString = "notificatin hub connectionstring";
//sender id for google cloud services
var senderIdGCM = "sender id from google gcm";
//tag registration (csv string), can be empty but not undefined
var registrationTagsCsv = ""; //test1, test2
var app = {
Initialize: function () {
//reg for onload event
this.AppStart();
},
AppStart: function () {
"use strict";
document.addEventListener('deviceready', app.onLoad, false);
document.addEventListener('deviceready', onDeviceReady.bind(this), false);
function onDeviceReady() {
// Handle the Cordova pause and resume events
document.addEventListener('pause', onPause.bind(this), false);
document.addEventListener('resume', onResume.bind(this), false);
// TODO: Cordova has been loaded. Perform any initialization that requires Cordova here.
};
function onPause() {
// TODO: This application has been suspended. Save application state here.
};
function onResume() {
// TODO: This application has been reactivated. Restore application state here.
};
},
onLoad: function () {
app.log("Initializing...");
//setup push notifications
Pushman.Initialize(connectionString, notificationHubPath, senderIdGCM,
app.onNotificationRegistered, app.onNotificationUnRegistered,
app.onNotificationInline, app.onNotificationBackground, app.onNotificationError);
//hookup cmd buttons
app.registerForPush();
//$("#register").click(app.registerForPush);
//$("#unregister").click(app.unRegisterForPush);
app.onAppReady();
},
registerForPush: function (a, c) {
app.log("Registering...");
//register for tags
Pushman.RegisterForPushNotifications(registrationTagsCsv);
},
unRegisterForPush: function (a, c) {
app.log("UnRegistering...");
//register for tags
Pushman.UnRegisterForPushNotifications();
},
onAppReady: function () {
app.log("Ready");
},
onNotificationRegistered: function (msg) {
app.log("Registered: " + msg.registrationId);
},
onNotificationUnRegistered: function () {
app.log("UnRegistered");
},
onNotificationInline: function (data) {
app.log("Inline Notification: " + data);
},
onNotificationBackground: function (data) {
app.log("Background Notification: " + data);
},
onNotificationError: function (error) {
app.log("Error: " + error);
},
log: function (msg) {
console.log(msg);
},
};
If you want to store the messages then you just need to add your code for storing to sql where the messages get received. You'll need an azure account to make this work, here you can get a free trail. It will allow you to send up to 1 million push notifications a month free of charge.
I think this article may be of use, it has more of a direct native workaround for your hybrid app to work

I'm working on a Cordova android app, and this seems to be a working solution
I'm developing cross platform applications. I'm able to request access to location using the Phone Gap API. If the user clicks okay, then I'm able to get the latitude and longitude using PhoneGap API and send it to the server.
However, I'm facing issues if the user clicks "Don't Allow" initially. After that, if he tries to refresh page, I want the device to show the popup again to request access to the location.
How do we do that in Single Page Applications?
var loadPanelMessage = ko.observable("Sipping..."),
loadPanelVisible = ko.observable(false),
lat = ko.observable(''),
lon = ko.observable('');
navigator.geolocation.getCurrentPosition(onSuccess, onError);
var onSuccess = function (position) {
lat(position.coords.latitude);
lon(position.coords.longitude);
timestamp(position.timestamp);
};
function onError(error) {
alert('code: ' + error.code + '\n' +
'message: ' + error.message + '\n');
//How should I handle the error, so that it asks for Geolocation again?
}
You cannot reshow that popup, it is shown by iOS and once user click's "Don't Allow" you cannot force that popup. All you can do is to let your user know about the situation and direct the user to iOS settings to enable location services for your app.
Here is a nice read about the problem:
https://medium.com/on-startups/96fa4eb54f2c
Based on the cordova plugins here org.apache.cordova.geolocation
All you need to do is a watchPosition to check the PositionError, and use also the cordova-plugin-dialogs to show the native notification
navigator.geolocation.watchPosition((function(_this) {
return function(position) {
// Do something here
};
})(this), function(error) {
var errorButton, errorMsg, errorTitle;
errorTitle = "Location Services";
errorButton = "Ok";
if (error.code === 1) {
errorMsg = "\"AppName\" needs access to your location. Please turn on Location Services in your device settings.";
}
if (error.code === 2) {
errorMsg = "This device is unable to retrieve a position. Make sure you are connected to a network";
}
if (error.code === 3) {
errorMsg = "This device is unable to retrieve a position. Make sure you have Location Services enabled for \"AppName\"";
}
if (error.code === 1 || error.code === 2 || error.code === 3) {
return navigator.notification.alert(errorMsg, errorDismissed(), errorTitle, errorButton);
}
}, {
enableHighAccuracy: true,
maximumAge: 20000,
timeout: 10000
});
