None of the answers on stackoverflow worked for me. A lot of them are for Ionic 1 or those answers are deprecated or they are not working for android device.
I have seen a lot of solutions on stackoverflow about getting current location of device but non of them seems to be working for Android .
what i have tried:-
using geolocation.getCurrentPosition() , which is working for IOS and browser but not for Android.
using this.geolocation.watchPosition() , which is working for IOS and browser but not for Android.
using navigator.geolocation.getCurrentPosition(),which is working for IOS and browser but not for Android.
using fiddle solution provided by this question getCurrentPosition() and watchPosition() are deprecated on insecure origins
Anyway , all of these are deprecated by google due to :-
getCurrentPosition() and watchPosition() are deprecated on insecure
origins, and support will be removed in the future. You should
consider switching your application to a secure origin, such as HTTPS.
See goo.gl/rStTGz for more details.
what worked for me is (https://ionicframework.com/docs/native/background-geolocation/ ) & (https://www.joshmorony.com/adding-background-geolocation-to-an-ionic-2-application/ ) both of these are based on background-geolocation plugin but,it's taking almost 50-55 sec on Android device, again it's working fine for ios
The problem with joshmorony(https://www.joshmorony.com/adding-background-geolocation-to-an-ionic-2-application/ ) solution is foreground is not working for Android physical devices but working fine for browser and ios. Background tracking is working fine , which is taking almost 50 sec to give lat & lng for the first time.
Please help me with this. I want a way to get current location in minimum time. For your info, I am using google javascript map sdk / api .
I tried every solution provided by all of you and others also on internet. Finally i found a solution.You can try this plugin cordova-plugin-advanced-geolocation (https://github.com/Esri/cordova-plugin-advanced-geolocation ) from ESRI . But this plugin will work for Android not IOS. For ios you can go with same old approach . i.e - using this.geolocation.getCurrentPosition(...) or this.geolocation.watchPosition(..).
Add cordova-plugin-advanced-geolocation Plugin Like this :-
cordova plugin add https://github.com/esri/cordova-plugin-advanced-geolocation.git
then Add below line at the top of Class / Component
declare var AdvancedGeolocation:any; //at the top of class
Now add these lines inside relevant function of component ( P.S. - I have included code for both Android & IOS)
//**For Android**
if (this.platform.is('android')) {
this.platform.ready().then(() => {
AdvancedGeolocation.start((success) => {
//loading.dismiss();
// this.refreshCurrentUserLocation();
try {
var jsonObject = JSON.parse(success);
console.log("Provider " + JSON.stringify(jsonObject));
switch (jsonObject.provider) {
case "gps":
console.log("setting gps ====<<>>" + jsonObject.latitude);
this.currentLat = jsonObject.latitude;
this.currentLng = jsonObject.longitude;
break;
case "network":
console.log("setting network ====<<>>" + jsonObject.latitude);
this.currentLat = jsonObject.latitude;
this.currentLng = jsonObject.longitude;
break;
case "satellite":
//TODO
break;
case "cell_info":
//TODO
break;
case "cell_location":
//TODO
break;
case "signal_strength":
//TODO
break;
}
}
catch (exc) {
console.log("Invalid JSON: " + exc);
}
},
function (error) {
console.log("ERROR! " + JSON.stringify(error));
},
{
"minTime": 500, // Min time interval between updates (ms)
"minDistance": 1, // Min distance between updates (meters)
"noWarn": true, // Native location provider warnings
"providers": "all", // Return GPS, NETWORK and CELL locations
"useCache": true, // Return GPS and NETWORK cached locations
"satelliteData": false, // Return of GPS satellite info
"buffer": false, // Buffer location data
"bufferSize": 0, // Max elements in buffer
"signalStrength": false // Return cell signal strength data
});
});
} else {
// **For IOS**
let options = {
frequency: 1000,
enableHighAccuracy: false
};
this.watch = this.geolocation.watchPosition(options).filter((p: any) => p.code === undefined).subscribe((position: Geoposition) => {
// loading.dismiss();
console.log("current location at login" + JSON.stringify(position));
// Run update inside of Angular's zone
this.zone.run(() => {
this.currentLat = position.coords.latitude;
this.currentLng = position.coords.longitude;
});
});
}
EDIT : First installation is always going fine. But Sometimes you might get errors for no reason in subsequent installations. To make this error (any error with this plugin ) go away.Follow these steps :
1. Remove this plugin from your project (including config.xml and package.json).
2. Delete/Remove android platform.
3. Delete plugins folder.
4. Now reinstall this plugin again, following the steps above.
I have gone through the problem and find the solution.
the best way to get geolocation of the user is to use this plugin https://ionicframework.com/docs/native/geolocation/
do not forget to add this is app.moudle.ts as its a provider.
by simply adding this code in app component i was able to get location( do not forget to import and add in constructor)
this.geolocation.getCurrentPosition({ enableHighAccuracy: true }).then((resp) => {
console.log(resp);
}, Error => {
console.log(Error);
}).catch(Error => {
console.log(Error);
})
i only have the same error while i was using ionic cordova run
android --livereload that is insecure origin
but when i use ionic serve i can see the response in browser and also after
using ionic cordova run android
just to confirm response in android i check the chrome debugger.
It works for me
import { Geolocation } from '#ionic-native/geolocation/ngx';
import { NativeGeocoder, NativeGeocoderOptions, NativeGeocoderResult } from '#ionic-native/native-geocoder/ngx';
geoencoderOptions: NativeGeocoderOptions = {
useLocale: true,
maxResults: 5
};
constructor(
private geolocation: Geolocation,
private nativeGeocoder: NativeGeocoder
) {
getCurrentLocation() {
this.geolocation.getCurrentPosition()
.then((resp) => {
this.getGeoencoder(resp.coords.latitude, resp.coords.longitude);
}).catch((error) => {
console.log('Error getting location', error);
});
}
//geocoder method to fetch address from coordinates passed as arguments
getGeoencoder(latitude, longitude) {
this.nativeGeocoder.reverseGeocode(latitude, longitude, this.geoencoderOptions)
.then((result: NativeGeocoderResult[]) => {
const address = this.generateAddress(result[0]);
})
.catch((error: any) => {
// alert('Error getting location' + JSON.stringify(error));
});
}
//Return Comma saperated address
generateAddress(addressObj) {
let obj = [];
let address = "";
for (let key in addressObj) {
obj.push(addressObj[key]);
}
obj.reverse();
for (let val in obj) {
if (obj[val].length)
address += obj[val] + ', ';
}
return address.slice(0, -2);
}
you need to provide the permission for Android app as follows:
<feature name="Geolocation">
<param name="android-package" value="org.apache.cordova.GeoBroker" />
</feature>
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_LOCATION_EXTRA_COMMANDS" />
I ran into a similar problem. When I build from the terminal with the --prod flag, I no longer see this error since it is now requesting position over https.
Built without --prod flag
Built using the --prod flag
Edit: Sorry for the format, I hope that this makes a little more sense. I used the following function in a service that I could call from anywhere to get the latitude, longitude, accuracy, and timestamp. The key though is using the --prod flag in the terminal when building the app.
this.geolocation.getCurrentPosition().then(position => {
let locationObj = {
lat: position.coords.latitude,
lon: position.coords.longitude,
timestamp: position.timestamp,
accuracy: position.coords.accuracy
};
resolve(locationObj);
})
this method is working for bot android and browser
watchLocation() {
this.watchLocationUpdates = this.geolocation.watchPosition({ maximumAge: 60000, timeout: 25000, enableHighAccuracy: true })
.subscribe(resp => {
this.latitude = resp.coords.latitude;
this.longitude = resp.coords.longitude;
this.altitude = resp.coords.altitude;
this.accuracy = resp.coords.accuracy;
this.altAccuracy = resp.coords.altitudeAccuracy;
this.heading = resp.coords.heading;
this.speed = resp.coords.speed;
this.timestamp = new Date(resp.timestamp);
});
}
I found solution for me: use google api https://www.googleapis.com/geolocation/v1/geolocate?key={API_KEY}
If platform Android I use google api.

I am working on a personal project and I am using flutter to develop an app (cross platform) that reads in the user's health data from google fit (Android) or Apple Health. I am using this package and even the EXACT same code like in the documentation (I am currently only testing on Android):
Future fetchStepData() async {
int? steps;
// get steps for today (i.e., since midnight)
final now = DateTime.now();
final midnight = DateTime(now.year, now.month, now.day);
bool requested = await health.requestAuthorization([HealthDataType.STEPS]);
if (requested) {
try {
steps = await health.getTotalStepsInInterval(midnight, now);
} catch (error) {
print("Caught exception in getTotalStepsInInterval: $error");
}
print('Total number of steps: $steps');
setState(() {
_nofSteps = (steps == null) ? 0 : steps;
_state = (steps == null) ? AppState.NO_DATA : AppState.STEPS_READY;
});
} else {
print("Authorization not granted - error in authorization");
setState(() => _state = AppState.DATA_NOT_FETCHED);
}
}
Then I am calling this function with await and I also have inserted the correct permission in all Android Manifest files:
Also I set up an OAuth2 Client ID for the project and added my google account as a test user.
BUT THE FUNCTION SETS THE VARIABLE STEPS ALWAYS TO NULL? The boolean variable "requested" is true, so it seems like the actual connection is working?
I am really disappointed by myself guys and I really need help - THANK YOU!
I tried adding the correct android permissions, asking for permissions explicitly, different time intervalls but nothing worked for me, I always got a null value back.
I'm trying to send the geolocation by ajax in intervals of 30 seconds in the background, since this application is being used to know the "real time" location of the deliverers at all times. The problem is that when you enable the plugin in the android version when generating the apk and installing it on the cell phone it doesn't work, even when you put the application in the background and put it back in the foreground it restarts completely.
These are the versions that I am using for the development of the application:
Cordova 10
Nodejs 14.16
JQuery 3.5
Structure:
js
login.js
home.js
index.html -- this is the login page where the login.js file is located
home.html -- this is the home page where the home.js file is located
login.js
document.addEventListener('deviceready', function () {
cordova.plugins.backgroundMode.enable();
});
home.js
let isSending = false;
let intervalId = null;
let email = window.localStorage.getItem("user_email");
let token = window.localStorage.getItem("token");
let path = window.localStorage.getItem("api_url");
let onMapSuccess = function (position) {
let latitude = position.coords.latitude;
let longitude = position.coords.longitude;
if (!isSending) {
$.ajax({
type: "GET",
url: path + "/geoTransportista/" + email + "/" + latitude + "/" + longitude,
headers: {
Authorization: "Bearer " + token,
"Content-type": "application/json",
},
beforeSend: function() {
isSending = true;
}
}).done((res) => {
if (res.state == "successful") console.log("ENVIO EXITOSO");
}).fail((err) => {
console.log(err);
}).always(() => {
isSending = false;
});
}
};
let onMapError = function (error) {
isSending = false;
}
let getLocation = () => {
navigator.geolocation.getCurrentPosition(onMapSuccess, onMapError, {
enableHighAccuracy: true,
});
return getLocation;
}
document.addEventListener('deviceready', function (e) {
intervalId = setInterval(getLocation(), 30000);
cordova.plugins.backgroundMode.on('activate', function (e) {
cordova.plugins.backgroundMode.disableWebViewOptimizations();
if (intervalId) clearInterval(intervalId);
intervalId = setInterval(getLocation(), 30000);
});
cordova.plugins.backgroundMode.on('deactivate', function (e) {
if (intervalId) clearInterval(intervalId);
intervalId = setInterval(getLocation(), 30000);
});
});
#justin is wrong it works on Cordova 10+ but it does not support GPS however you can recall GPS function when you resume to app. I'm on Cordova 11.0.0 and its working fine. Also you can take a look a cordova-plugin-advanced-background-mode
cordova-plugin-background-mode does not work on Cordova 10. You can try downgrade to Cordova 9. The repo seems inactive for a while now, not sure if the author will ever fix it.
I have a Node js API written in express framework.
I am sending some data over all my api does is calculate number of Packages to make For example :- 100/10 = 10 packages to make.
Loops and creates packages in sales force and firebase one by one.
Works fine from postman.
Problem:
When i try to hit the api from my app it works fine when the package count is <= 10. when > 10 ,Lets say 25 it calculates packages and run a loop of 25 and creates packages,crashes after 11th iteration and restarts the route, calculate again 25 packages to create and resulting in "Over weight error".
1- thought it was from android error may be i was hitting two request one after an other ( this was not the case ).
2- Tried sending header "Connection" "Keep-Alive" ( as Postman does ) not working.
3- tried to put up the timeout in the below code it did not work either ( tried variations of time out like 0, 50,000 ms )
else {
console.log('=====By Item=============');
const supplierFinishedGood = {
Name: parentBatchDoc['itemName'],
Supplier_Product__c: parentBatchDoc['id'],
Package_Size__c: 'a090S000001ZQ5kQAG', // Hard coded PackageSize in 'Gram' as per SALESFORCE
On_Hand_Amount__c: childBatch['batchWeight']
}
console.log('=====By Item============= 2');
const SupplierFinishedProductID = await createSupplierFinishedProduct(supplierFinishedGood, bearerToken);
const Quantity_Packaged__c = Math.floor((childBatch['batchWeight'] - childBatch['batchTestAmount']) / noOfPackage);
console.log('=====By Item============= 3');
//console.log('Quantity_Packaged__c ==== Remaining_Grams_Available_for_Packaging__c', Quantity_Packaged__c, parentBatchSalesforce['Remaining_Grams_Available_for_Packaging__c']);
for (let index = 0; index < noOfPackage; index++) {
if (parentBatchSalesforce['Remaining_Grams_Available_for_Packaging__c'] > Quantity_Packaged__c) {
let package = {
Batch__c: childId,
Product__c: SupplierFinishedProductID,
Inventory_Location__c: 'a030S000003x7M7QAI', //Hard coded InventoryLocation 'StorageFinished' as per SALESFORCE
Number_Of_Items__c: noOfItemInPackage,
Quantity_Packaged__c: Quantity_Packaged__c,
Date_Packaged__c: datePackaged,
Expiration_Date__c: expirationDate
};
console.log('Before creating apcaktge ', index);
const packageID = await createPackage(package, bearerToken);
console.log('After creating package ', index, parentBatchSalesforce['Remaining_Grams_Available_for_Packaging__c']);
package['parentBatchId'] = parentId;
package['status'] = 'Ready to checkout';
package['uid'] = packageID;
const packageFBResponse = await db.collection('packages').doc(packageID).set(package, { merge: true });
reponseBody.push(packageID);
} else {
console.log('======Over
Weight====');
}
Above code is what produces the error.
There is a If condition before this it works fine i have tested it
as it has some other scenario.
End result should not be a timeout error.
API should create all the packages and return the result.
I have found a workaround. I am Playing around batch status and my code returns me the IDs which i need and packages are created.
This is not the ultimated best solution it is a work around. i am still open to know what the actual problem is.
parentBatchDoc['childBatches'][childId]['batchStatus'] = "In Processing";
const parentBatchDocResponse = await db.collection('batches').doc(parentId).set(parentBatchDoc, { merge: true });
if(parentBatchDoc['childBatches'][childId]['batchStatus'] !== "In Processing"){
===================Rest of the case of =======================

While developing a Progressive-Web-App the following Problem occurred:
Standalone mode works perfectly without including the service worker - but does NOT work with.
Without Service-Worker a2hs (added to Homescreen) PWA gets correctly started in "standalone"-Mode.
After adding the Service-Worker (a2hs + installed / Web-APK) PWA opens new Tab in new Chrome-Window.

The following questions / answers were considered - but no solution was found:
PWA wont open in standalone mode on android
WebAPK ignores display:standalone flag for PWA running on local network
PWA deployed in node.js running in Standalone mode on Android and iOS
Technical Background
The Moment you add your Service-Worker (along all other PWA-Requirements) your App gets created as an Real PWA - with Web-APK getting installed.
Therefore you also need to use Default-HTTPS-Port 443 - make sure you use a valid HTTPS-Certificate.
Before adding the Service-Worker, this mandatory requirement was missing so your PWA was NOT installed and therefore needed less other requirements to be displayed in "standalone-mode".
It's just a shame that this is nowhere documented... and we had to "find out" for ourselves.
Short-List of Mandatory Requirements for "Installable Web-APK":
(As we could not find a full List, i try to include all Points)
Registered Service-Worker (default-implementation like yours is enough)
manifest.json (yours is valid)
https with valid certificate
https default-port (443, eg. https://yourdomain.com/test/)
... for the rest just check chrome audit tool (HINT: you don't need to pass all requirements - your web-apk should work when switching to https-default-port)
When gps is enabled geolocationsuccess work perfectly. But when gps diabled it not calling geolocationerror in mobile device.Working on ionic framework using phonegap geolocation for checking is gps enable or not. codes are here
var locOptions = {
maximumAge : 10000,
timeout : 5000,
enableHighAccuracy : true
};
function onLocationSuccess(position) {
console.log(position);
// alert('success');
$rootScope.pos = new google.maps.LatLng(position.coords.latitude,
position.coords.longitude);
var geocoder = new google.maps.Geocoder();
geocoder.geocode({'latLng': $rootScope.pos}, function address(results, status) {
if (status == google.maps.GeocoderStatus.OK) {
if (results[1]) {
$rootScope.currentposition = results[1].formatted_address;
console.log($rootScope.currentposition);
if($scope.switchToState=='signedIn'){
$ionicLoading.hide();
$http.get($rootScope.url +'api/price/?key=movo1026868hk738hkl')
.success(function(response) {
$rootScope.truckfare=response.datasets;
});
console.log('reached here2');
$state.go('app.home');
}
else{
$ionicLoading.hide();
$state.go('start');
}
}
}
});
}
// onError Callback receives a PositionError object
//
function onLocationError(error) {
alert("Geolocation error: #" + e.code + "\n" + e.message);
}
navigator.geolocation.getCurrentPosition(onLocationSuccess, onLocationError, locOptions);
Geolocation API will not give you an error if the GPS is off because that is not an error state. It will just timeout if it is not able to get a lock in the time limit you specify.
Unfortunately, this is a real problem. If you turn off GPS and Geolocation API times out, you will not be able to make it work again unless you restart a whole application. So even if you turn GPS back online API will not work again unless an application is restarted.
There's a simple workaround here. Before you initialize Geolocation API check if GPS is online. You can do that using this PhoneGap/Cordova plugin:
https://github.com/mablack/cordova-diagnostic-plugin
Essentially, this plugin will solve your initial problem + problem I mentioned you before.
