I'm currently working on web-app using apache cordova, ionic and google map.
I'm getting issues trying to load correctly the google map js api. The problem is that the app don't work on my device but works just fine when I emulate it on Ripple.
So I have a controller for a Ionic View, when the user enter this view a condition check if the google maps api is loaded, if not we load it and then start using the GM Api. I can't figure where it has gone wrong.
Here is the condition making the call for the loading function...
$scope.$on('$ionicView.loaded', function () {
var test = false;
if (test) {
alert("Google Map api fully loaded");
}
else {
alert("Google map api not loaded"); //The alert is fired.
$scope.loadApi();
}
});
The loading function
$scope.loadApi = function () {
if ($cordovaNetwork.isOnline()) //check if device is connected {
alert('Loading api'); //The alert is fired
$.getScript('https://maps.googleapis.com/maps/api/js?sensor=false&key=xxx',
function () {
alert("Api Loaded"); //Alert not fired on device
$scope.startGeo(); // The function isn't called so no map
});
}
else {
alert('Check your connexion');
}
};
Here is the html part, in case I forgot something....

I've tried many things such as using angular-load, replacing the getScript function by an ajax call (that is basically just the same thing), tried this answer to see if it could help..
Thanks for your help.
FIRST SOLUTION
Solved my problem by replacing the Google Map loading links.
index.html
Installed the whitelist plugin and added in the head :
<meta http-equiv="Content-Security-Policy" content="default-src *; script-src 'self' 'unsafe-inline' 'unsafe-eval' *; style-src 'self' 'unsafe-inline' *">
Replaced google Map loading link :
<script src='//maps.googleapis.com/maps/api/js?sensor=false'></script>
Got rid of the https: from the link.
controller.js
In the map's controller :
The loading function, I replaced the https protocol by the http one.
$scope.loadApi = function () {
if ($cordovaNetwork.isOnline()) {
console.log($scope.logs.apiLoading);
$.getScript('http://maps.googleapis.com/maps/api/js?sensor=false', function () {
$scope.startGeo();
});
}
else if($cordovaNetwork.isOffline()) {
alert($scope.logs.deviceOffline);
}
};
SECOND SOLUTION (Using angular-google-maps)
Just a reminder of angular google map's config in the app.js
For those using Angular google Map. The library load google map automatically, you just have to set it up properly. There is also an event to check if the google map is loaded. I wasn't aware of this at the time, and mixed everything, angular google maps loading process with mine. etcetera :)
angular.module('myapp').config(function (uiGmapGoogleMapApiProvider) {
uiGmapGoogleMapApiProvider.configure({
key: 'myKey',
v: '3.20', //defaults to latest 3.X anyhow
libraries: 'weather,geometry,visualization,places'
});
})

I just build a flutter web project. I hosted it on github pages. After successfully from creating repository to deploying project I am getting this following error...
(index):46 Uncaught ReferenceError: _flutter is not defined
I don't understand why is this happening. I tried flutter clean.
I searched for the solution. but many people suggested that run flutter clean command but it made no effect on the project.
Here is my code code for web build.

Uncaught ReferenceError: _flutter is not defined is may caused by wrong deployed folder.
you have to delpoy web directory insted of build/web
here some reference from github issue: https://github.com/flutter/flutter/issues/107448#issuecomment-1181591460
or you may try this solution :
Is `Flutter build web` supposed to output a file called flutter.js? Because it does not by me :(
I am trying to set up my facebook instant game.
I have followed https://developers.facebook.com/docs/games/instant-games/test-publish-share , to test locally then deploy into production.
When testing, everything works fine. However, in production, nothing shows up (black screen) when I open my game. <app-root> doesn't render, app-home's constructor isn't called and it takes up 0x0 pixels.

'initialized' is printed in the console, when I open the game. There are two errors there with it (which might have to do with the error I am having)

The 404 error (resource not found) is a .js file which I checked was included in the .zip file which I uploaded.
This is what i see when I inspect element on the game

Also, on mobile, nothing is displayed (white screen)
Any help would be greatly appreciated.
Thanks! :)
I've been stuck on this issue for 10+ hours now and I'm having no luck in fixing it by myself. The problem is that I'm trying to use this dialog plugin on my Cordova app but its not working. I don't even think that the deviceready script is working.
Any questions feel free to ask

The <plugin name="cordova-plugin-dialogs" spec="^1.3.3" /> is in config.xml
Your code in <script> tag seems alright. If you have added the dialogs plugin using -
cordova plugin add cordova-plugin-dialogs
that should work fine.
And don't add src="cordova.js" for the script containing your code. Just do this -
<script>
document.addEventListener("deviceready", onDeviceReady(), false)
function onDeviceReady() {
navigator.notification.alert(
'Script has loaded', // message
alertDismissed, // callback
'Loaded', // title
'Done' // buttonName
);
};
function alertDismissd() {
// do something
};
</script>
If it still doesn't work, can you inspect in Google Chrome, see and list the error messages under Console tab? There might be some error before that <script> if that onDeviceReady() is not triggered.
UPDATE after seeing error messages from here -
Remove <script src="cordova_plugins.js"></script> That's not required. Plugins are directly called from js.
Cannot read property 'alert' of undefined => the plugin is not properly installed. Install it first using cordova plugin add cordova-plugin-dialogs in cmd.
Remove <script src="js/index.js"></script>. As you are doing everything inside <script> tag, you don't need index.js or its js contents (has errors).
I reinstalled windows 10 and reinstalled cordova as a whole. Now all plugins work :) sorry if this isnt the answer you wanted but it worked for me! Have a good day!
I am completely new to developing applications that bring in maps. I am developing a mobile application using Apache Cordova, Javascript, HTML5, and Leaflet. On the index.html page, I need to display a map on the page. I have a DIV on the page for the map but the map does not display. I have tried it in a few different emulators with no luck. I have made sure that the img-src attribute allows for images to be pulled in from the correct resource. I have also tried a few different free providers. Lastly, I moved the javascript code from the bottom of the index.html file to the onDeviceReady() handler in the index.js file. My code for the two files are below. Can anyone tell why my map isn't showing? I have followed the examples I viewed and it looks fine from what I can tell, but that doesn't mean a thing. Any help would be greatly appreciated. Thanks.
index.js file:

In light of mattesCZ's comment above, I decided to change the height defined on the map DIV from a percentage to pixels and the map displayed with no problem at all.
I have an ionic cordova Android app where I am trying to use the Google maps API. Specifically I want to use the geocoder feature. In my Cordova Android app code I have a line of code to get access to the geocoder:
var geocoder = new google.maps.Geocoder();
This line of code is in the ''file and is throwing an error: 'ReferenceError google is not defined'.
I am adding the google maps api in the index.html file as follows:

I can't see why google is undefined?
You are loading the Google Maps API after all your other scripts, so when you try to use google.maps it doesn't exist yet.
Move <script src="http://maps.googleapis.com/maps/api/js?libraries=places&sensor=false"></script> to the top to fix it.
Look for the meta security tag. and debug the ionic app using chrome://inspect/#devices in the chrome browser. You will notice the meta security errors.
