Felgo 2.14.0 introduced Felgo Live Code Reloading, which reduces your deployment time from minutes to seconds. Felgo 2.14.2 now adds support for using native cross-platform plugins with live code reloading.

2.14.2 also adds improvements to the SocialView components and adds improvements for Navigation components.

What is Felgo Live Code Reloading

Felgo Live reloads your project on every connected device, within seconds after code changes. This reduces the long compilation and deployment times, to only a couple of seconds. Felgo Live also allows you to run and test your applications on iOS from a Windows or Linux desktop. You don’t need to install any native SDKs for deployment with Felgo Live.


Watch this video for a quick demo of Felgo Live in action:


Felgo Live displays your app or game with the Live Client application. The desktop Live Client is part of your Felgo installation. For Android and iOS, you can download the Live Client apps in the app stores. For most projects those Live Client apps are sufficient. They have several Felgo Plugins and most of the Qt modules configured, so you can use them with Felgo Live.

Soon you will have the option to extend your own project with the live reloading feature, to build custom Live Clients. This allows you to use any custom C++ or native code together with live reloading for QML & JavaScript. This will also make it possible to use even more Felgo Plugins and features with Felgo Live.

How to Use Felgo Live

Felgo Live is super easy to use. We already covered that in our last blog post, you can read it here: How to use Felgo Live

What are Felgo Plugins

Do you want to add advertisements to your app or game? Do you want to add analytics to track and understand your audience? Do you need push notifications or other cloud services?

Felgo got you covered! With Felgo Plugins, you can add such native cross-platform plugins with just a few lines of code.




Beginning with Felgo 2.14.2, you can use many of those plugins also with Felgo Live. This helps you test a plugin without performing any extra setup steps. Felgo Live has several plugins configured already, so you can use them right away. For some plugins, this is not possible yet.

Use Felgo Plugins with Felgo Live

Here is a short video showing how to use Felgo Plugins with Felgo Live:


The following list shows which plugins you can already use with Felgo Live. There are no extra setup steps needed. For some services you will need to create an account at the service provider website. You can find the website links in the code examples below.

Access Felgo Plugins

To use Felgo Plugins in your QML code, add

import Felgo 3.0

at the top of your QML file.

Google AdMob

The AdMob plugin offers several ad formats to optimize your monetization. It features banner ads, interstitial ads and rewarded videos.

AdMobBanner {
adUnitId: "ca-app-pub-3940256099942544/6300978111"


Charboost is another advertisement service that offers interstitial ads. You can also use it to cross-promote your apps & games.

Chartboost {
appId: "your App Id from www.chartboost.com"
appSignature: "your App Signature from www.chartboost.com"
shouldRequestInterstitialsInFirstSession: true

onPluginLoaded: {
onInterstitialCached: {
onInterstitialFailedToLoad: {
console.debug("InterstitialFailedToLoad at location:", location, "error:", error)

Google Analytics

Google Analytics offers in-depth analysis how users interact with your apps & games.

GoogleAnalytics {
propertyId: "your Property Id from analytics.google.com"

onPluginLoaded: {
logEvent("Felgo Live","Test App Loaded","Test Events", 1)

Flurry Analytics

Flurry is another popular analytics service that’s provided as Felgo Plugin. Here is a short example how to use it:

Flurry {

apiKey: "your Api Key from y.flurry.com"

onPluginLoaded: {
flurry.logEvent("App started");

Local Push Notifications

Schedule local notifications based on an upcoming point in time or a time interval.

This code examples schedules a notification 5 seconds after pressing the button. If you close the app, or move it to the background, the notification will be received as push notification.

NotificationManager {
id: notificationManager
onNotificationFired: {
// Log output when the notification is fired. You can find the log output in the Live Server
console.debug("Notification fired: " + notificationId)

Notification {
id: testNotification
notificationId: "testNotification"
message: "Hey there!"
timeInterval: 5 // in seconds

AppButton {
text: "Schedule Notification"
onClicked: {
// Cancel old notification if scheduled
// Schedule testNotification

More Plugins

You can find the full list of Felgo Plugins here: Felgo Plugins

The following plugins will have no or limited functionality with Felgo Live at the moment: In-App purchases, Facebook, Google Firebase, Game Center, Google Cloud Messaging, OneSignal, HockeyApp.

Of course, you can still use those plugins with standard local deployment, as used to. Nothing changes for your existing projects.
