Phonegap google maps api query not working - android

I am developing a simple android app using phonegap that sends a google maps geocoding api request with lat,lan location and returns an address.
When working using my desktop, everything works fine!
Once I build the app using the adobe phonegap cloud builder, it does not work. in addition, I am unable to debug as nothing is presented on the app. it simply shows an empty value.
Could this be a CORS issue? HTTPS? Some issue using a mobile user-agent for google maps requests? I am unsure. appreciate any help!
this is my code:
function maps_api(latlng){
var divdata = $('div#data');
divdata.text('cleared');
updateStatus('Starting google api: ');
var xhttp = new XMLHttpRequest();
xhttp.onreadystatechange = function() {
if (this.readyState == 4 && this.status == 200) {
updateStatus(this.responseText);
var myArr = JSON.parse(this.responseText);
var divdata = $('div#data');
divdata.text(myArr["results"][0]["formatted_address"]);
}
else
{
updateStatus(this.responseText);
var divdata = $('div#data');
divdata.text(xhttp.statusText);
}
};
xhttp.open("GET", "https://maps.googleapis.com/maps/api/geocode/json?latlng=" + latlng + "&key=myprivatekey", true);
xhttp.send();
}

I managed to resolve this by installing the whitelist-plugin and allowing communication to google maps server

Protect Google Maps API key with Restriction for Ionic app

I am working on ionic app and I want to redirect user from app to google map application for showing directions to user but when I am setting a Key restriction to NONE it works perfectly.
But when I set restriction to Android apps and provide a proper Package name & SHA-1 It give me error: Google Maps JavaScript API error: RefererNotAllowedMapError.
I think it is because:
ionic app is basically a webview. (which I am using)
and if this is the reason how can I protect my API key?
I use code to open Google map in android app is
showDirection(currentLocation, destLocation) {
let destination = destLocation.latitude + ',' + destLocation.longitude;
var directionsService = new google.maps.DirectionsService;
directionsService.route({
origin: currentLocation,
destination: destination,
travelMode: 'DRIVING'
}, function (response, status) {
if (status === 'OK') {
let mapUrl = 'http://maps.google.com/?';
var route = response.routes[0];
route.legs.forEach((value, index) => {
if (index == 0) {
mapUrl += 'saddr' + value.start_address + '&daddr=' + value.end_address;
} else {
mapUrl += '+to:' + value.end_address;
}
});
window.location.href = mapUrl;
} else {
window.alert('Directions request failed due to ' + status);
}
});
}
can someone help?
Android app restriction is only valid for Google Maps SDK for Android. In your case when you use Ionic with WebView and Google Maps JavaScript API the only supported restriction is HTTP referrer.
You can check yourself which type of restriction is supported by each API on this page
https://developers.google.com/maps/faq#keysystem
In order to set valid HTTP referrer restriction in your Ionic app you should check what value has window.location.href when you open a map in your WebView.
For example, if the window.location.href is something like file://some/path you should use this value as referrer.
Also note that URLs with a file:// protocol require special representation as explained in
https://developers.google.com/maps/documentation/javascript/get-api-key#restrict_key
Note: file:// referers need a special representation to be added to the key restriction. The "file://" part should be replaced with "_file_url_" before being added to the key restriction. For example, "file:///path/to/" should be formatted as "_file_url_//path/to/*". After enabling file:// referers, it is recommended you regularly check your usage, to make sure it matches your expectations.
UPDATE
I believe you can avoid using DirectionsService and open Google Maps directly with Google Maps URLs in directions mode
The code snippet might be
showDirection(currentLocation, destLocation) {
const destination = destLocation.latitude + ',' + destLocation.longitude;
let mapUrl = "https://www.google.com/maps/dir/?api=1";
mapUrl += "&origin=" + currentLocation;
mapUrl += "&destination=" + destination;
mapUrl += "&travelmode=driving";
mapUrl += "&dir_action=navigate";
window.location.href = mapUrl;
}
In this scenario you don't need using Google Maps JavaScript API, you don't need an API key and you don't pay for using Maps JavaScript API service.

xamarin form disallowed_useragent with webview when using Google api

I am working on Xamarin cross platform app where I am implementing Google Sign on.
From browser and postman, I am able to authticate and get user data using api.
But when I am using in Xamarin forms webview, I am getting error of disallowed_useragent .
Because Google no longer supports webview request. So I need to set user agent in andriod as well as iOS app OR something to setup in PCL project that will be used by both platform.
I didn't find solution to solve this problem
Here is my code :
private async void LoginWithGoogle_Clicked(object sender, EventArgs e)
{
ShowLoader(true);
var authRequest =
"https://accounts.google.com/o/oauth2/v2/auth"
+ "?response_type=code"
+ "&scope=email%20profile"
+ "&redirect_uri=" + Constants.GoogleRedirectUri
+ "&client_id=" + Constants.GoogleClientId;
var webView = new WebView
{
Source = authRequest,
HeightRequest = 1
};
webView.Navigated += WebViewOnNavigatedForGoogle;
Content = webView;
ShowLoader(false);
}
Check out https://github.com/xamarin/Xamarin.Auth, there is working solution :)

Cannot select item with Google drive picker on Android Browser

I am using the google drive picker to open files from google drive within a web page. The dialog works correctly in most browsers including mobile Chrome, however, with the Android browser, tapping on a file does not select it.
This is using a Samsung Galaxy Note 1 with factory settings + updates. I can replicate this problem with an unrelated application, mindmup which I will use this as the reproduction steps given its publicly accessible:
i)
http://www.mindmup.com/
From any machine, create and save a mindmap to your google drive
ii)
With the Android browser, revisit the site and choose File -> Open ->From Google Drive
iii)
The google drive picker will appear and display your file. The dialog will be scrollable and can be cancelled but tapping a file will not select it.
How can I fix this problem in the Android browser?
The official Google response is that the picker does not support Android. Huh. Works on IOS. Maybe they could add that little tidbit to their documentation.
No other recourse but to implement my own using the files.list api:
retrieveAllFiles = function(callback) {
var retrievePageOfFiles = function(request, result) {
request.execute(function(resp) {
result = result.concat(resp.items);
var nextPageToken = resp.nextPageToken;
if (nextPageToken) {
request = gapi.client.drive.files.list({
'pageToken': nextPageToken,
'q' : 'trashed = false'
});
retrievePageOfFiles(request, result);
} else {
callback(result);
}
});
};
var initialRequest = gapi.client.drive.files.list({
'q' : 'trashed = false'
});
retrievePageOfFiles(initialRequest, []);
};

Facebook Notification redirect to external URL

We are trying to implement a simple solution to our website developed via Flex and mobile apps developed using Adobe Air.
1) Our users would like to import their facebook friends onto website via www.ourwebsite.com and also via the Ourwebsite android, ios & blackberry apps.
2) We want to use the Facebook Requests dialog which allows users to select their friends and send multiple invitations at a time
3) When the recepient clicks on the notification he receives
in case of web, it should direct the notification recipient to www.ourwebsite.com
in case of mobile app, it should re-direct to respective appstore to download our app.
We tried several configurations but it's not working for us.
As previously said we have developed our website using Adobe Flex and our Mobiles apps run using Adobe Air. Do we need to install the Facebook native SDK's into our code?
Strangely the exact same requirement is working for www.naaptol.com and 9lessons.info.
But we're unable to achieve the same technique.
Can anyone guide us or advise if we're missing any important aspect of Facebook App & its policies.
Thank you.

So if I think I am understanding this right, you want to be able to open a link differently based upon the platform they are on. Here is some js that will do it for ios and android. If they have your app installed it will launch the app, otherwise it will send them to the app store
// if iPod / iPhone, display install app prompt
if (navigator.userAgent.match(/(iPhone|iPod|iPad);?/i) || navigator.userAgent.match(/android/i)) {
var store_loc = "itms://itunes.com/apps/youriOSApp";
var href = "yourPrefix://";
var is_android = false;
if (navigator.userAgent.match(/android/i)) {
store_loc = "https://play.google.com/store/apps/details?id=air.com.your.app";
is_android = true;
}
var app_loc = href;
if (is_android) {
var w = null;
try {
w = window.open(app_loc, '_blank');
} catch (e) {
// no exception
}
if (w) {
window.close();
} else {
window.location = store_loc;
}
} else {
var timeout = null;
window.location.replace(app_loc);
timeout = setTimeout(function () {
"use strict";
window.location = store_loc;
}, 300);
onblur = function () {
"use strict";
clearTimeout(timeout);
};
}
}

Create a link that opens the appropriate map app on any device, with directions to destination

I rather thought this would not be so hard to find out but appearantly it is not easy to find an awesome cross device article, like you'd expect.
I want to create a link which opens either the mobile device's browser and surf to google maps OR open a maps app (Apple Maps or Google Maps) and directly starting a route, i.e.: start at the current location, end at a given point (lat/long).
I can test on two devices (beside browserstack), an Android and an iPhone.
The following link works only on the Android:
Take me there!
Clicking this link in iPhone's Chrome, this weirdly opens Google Maps in desktop version with ads on the mobile app...
This one only works on iOS, opening Apple Maps asking me to enter a start location (i can pick "Current Location") and start the route = desired behavior. Clicking this link completely fails on Android:
Take me there!
Notice the maps:// protocol.
Is there an elegant cross device way of creating such a link? One link that works on all main mobiles?
Thanks
UPDATE: Solution found (kinda)
Here is what I've come up with. It's not quite what I imagined, though it's working.
var ua = navigator.userAgent.toLowerCase(),
plat = navigator.platform,
protocol = '',
a,
href;
$.browser.device = ua.match(/android|webos|iphone|ipad|ipod|blackberry|iemobile|opera/i) ? ua.match(/android|webos|iphone|ipad|ipod|blackberry|iemobile|opera/i)[0] : false;
if ($.browser.device) {
switch($.browser.device) {
case 'iphone':
case 'ipad':
case 'ipod':
function iOSversion() {
if (/iP(hone|od|ad)/.test(navigator.platform)) {
// supports iOS 2.0 and later: <http://bit. ly/TJjs1V>
var v = (navigator.appVersion).match(/OS (\d+)_(\d+)_?(\d+)?/);
return [parseInt(v[1], 10), parseInt(v[2], 10), parseInt(v[3] || 0, 10)];
}
}
var ver = iOSversion() || [0];
if (ver[0] >= 6) {
protocol = 'maps://';
}
else {
protocol = 'http://maps.google.com/maps';
}
break;
case 'android':
default:
protocol = 'http://maps.google.com/maps';
break;
}
a.attr('href', protocol + href)
the maps:// protocol is the url scheme for the apple maps app, which will only start working on ios 6 or higher. There are ways to test if gmaps is installed and then chose what to do with the url, but that was kind of too much for what I intended. So i just ended up creating a maps:// OR maps.google.com/ link, using the above parameters.
** UPDATE **
sadly, $.browser.device don't work since jquery 1.9
(source - http://api.jquery.com/jquery.browser )
I haven't worked much with phones, so I dont't know if this would work. But just from a html/javascript point of view, you could just open a different url depending on what the user's device is?
<a style="cursor: pointer;" onclick="myNavFunc()">Take me there!</a>
function myNavFunc(){
// If it's an iPhone..
if( (navigator.platform.indexOf("iPhone") != -1)
|| (navigator.platform.indexOf("iPod") != -1)
|| (navigator.platform.indexOf("iPad") != -1))
window.open("maps://www.google.com/maps/dir/?api=1&travelmode=driving&layer=traffic&destination=[YOUR_LAT],[YOUR_LNG]");
else
window.open("https://www.google.com/maps/dir/?api=1&travelmode=driving&layer=traffic&destination=[YOUR_LAT],[YOUR_LNG]");
}
Interestingly, http://maps.apple.com links will open directly in Apple Maps on an iOS device, or redirect to Google Maps otherwise (which is then intercepted on an Android device), so you can craft a careful URL that will do the right thing in both cases using an "Apple Maps" URL like:
http://maps.apple.com/?daddr=1600+Amphitheatre+Pkwy,+Mountain+View+CA
Alternatively, you can use a Google Maps url directly (without the /maps URL component) to open directly in Google Maps on an Android device, or open in Google Maps' Mobile Web on an iOS device:
http://maps.google.com/?daddr=1+Infinite+Loop,+Cupertino+CA
just bumped in this question and found here all the answers
I took some of the codes above and made simple js function that works on
android and iphone (it supports almost every android and iphones).
function navigate(lat, lng) {
// If it's an iPhone..
if ((navigator.platform.indexOf("iPhone") !== -1) || (navigator.platform.indexOf("iPod") !== -1)) {
function iOSversion() {
if (/iP(hone|od|ad)/.test(navigator.platform)) {
// supports iOS 2.0 and later
var v = (navigator.appVersion).match(/OS (\d+)_(\d+)_?(\d+)?/);
return [parseInt(v[1], 10), parseInt(v[2], 10), parseInt(v[3] || 0, 10)];
}
}
var ver = iOSversion() || [0];
var protocol = 'http://';
if (ver[0] >= 6) {
protocol = 'maps://';
}
window.location = protocol + 'maps.apple.com/maps?daddr=' + lat + ',' + lng + '&ll=';
}
else {
window.open('http://maps.google.com?daddr=' + lat + ',' + lng + '&ll=');
}
}
The html:
<a onclick="navigate(31.046051,34.85161199999993)" >Israel</a>
This works for me on all devices [ iOS, Android and Window Mobile 8.1 ].
Does not look like the best way by any means... but cannot be more simpler :)

var request = {

directionsService.route(request, function (response, status) {

}
});
});
}
Well no, from an iOS developer prospective, there are two links that I know of that will open the Maps app on the iPhone
On iOS 5 and lower: http://maps.apple.com?q=xxxx
On iOS 6 and up: http://maps.google.com?q=xxxx
And that's only on Safari. Chrome will direct you to Google Maps webpage.
Other than that you'll need to use a URL scheme that basically beats the purpose because no android will know that protocol.
You might want to know, Why Safari opens the Maps app and Chrome directs me to a webpage?
Well, because safari is the build in browser made by apple and can detect the URL above. Chrome is "just another app" and must comply to the iOS Ecosystem. Therefor the only way for it to communicate with other apps is by using URL schemes.
Simple URL :
https://www.google.com/maps/dir/?api=1&destination=[LAT],[LNG]
This url is specific for routing.
Reference
I found that this works across the board:
<a href="https://www.google.com/maps/place/1+Fake+Street,+City+Province/State>Get Directions</a>
For desktops/laptops the user has to click Directions when that map loads, but from my testing all mobile devices will load that link in the Google Maps app without difficulty.
Based on the documentation the origin parameter is optional and it defaults to the user's location.
... Defaults to most relevant starting location, such as user location, if available. If none, the resulting map may provide a blank form to allow a user to enter the origin....
ex: https://www.google.com/maps/dir/?api=1&destination=Pike+Place+Market+Seattle+WA&travelmode=bicycling
For me this works on Desktop, IOS and Android.
The URL syntax is the same regardless of the platform in use
String url = "https://www.google.com/maps/search/?api=1&query=" + latitude + ","+
longitude;
In Android or iOS the URL launches Google Maps in the Maps app, If the Google Maps app is not installed, the URL launches Google Maps in a browser and performs the requested action.
On any other device, the URL launches Google Maps in a browser and performs the requested action.
here's the link for official documentation
https://developers.google.com/maps/documentation/urls/guide
