I connect to device via serial port for read some data from it. I need to send this data to specific web page's DOM.
We already tried communication with content_scripts but it cannot work. I develope packaged application and content_scripts is not working in packaged application.

Cross-Origin Resource Sharing (CORS)
CORS is a mechanism that browsers use to control how one site accesses the resources of another site. It is designed such that, by default, one web-site is not allowed to make HTTP requests to another site using XHR or fetch. This prevents scripts on another site from acting on behalf of the user and from gaining access to another site’s resources without permission.
When using , , or , the browser automatically blocks access to pixels when it knows that an image is coming from another site and the CORS policy disallows access to data.
WebGL requires access to the image data in order to be able to render the image. Therefore, images to be rendered using WebGL must only come from servers that have a CORS policy configured to work with the domain that serves your application.
So if you want to still use canvaskit import them to assets folder and use it as a local asset
I have created a canvas power app. I am trying to use the paypal API: https://developer.paypal.com/docs/subscriptions/integrate/ ,which gives you html to embed into your code. I know Power Apps is a no-code platform, but are you be able to connect a Canvas app to a Web Resource with html?
you cannot use javascript directly in your canvas app but there is something called PowerApps component framework. you can use PCF to have coded component in your canvas app.
There is an pcf gallery as well which contains community crated pcf controls which could be directly used.
In addition, it is not required if you want to consume 3rd party api that you use javascript. There is something called custom connectors/ or out of box connectores in power automate, you can call power automate (flows) from your canavas app and consume output/results from your flow.
Take a look at this connector article
I have an android app working this way:
User read QR-code with my specific URL
If the app installed it intercepts this URL and handles it somehow.
If app not installed standard browser opens this URL and it leads to Google play on app page.
When user install and run app first time it read browser's history and look for my URL.
If app found URL in browser's history then it handles this URL again.
Is it possible to implement this behavior on iPhone/iPad?
I suppose key features here are to read browser history and to intercept http URL's.
If this is impossible how would you implement this thing on iOS?
Thanks in advance for your help.
You can use custom application URLs in the form: myApp://... iOS will automatically launch the application if present. The logic for handling the 'not-installed' case has to be in the QR code scanning app. can be handled by the scanned website via a forwarding link using the iOS custom URL scheme (this might be useful for usage stats).

I have developed a simple Flex application that allows to a Facebook user to record audio. This application is published in facebook posts as SWF video (using "source" parameter on facebook post). My SWF communicates to a CMS backend to receive some parameters and to upload the audio file once it is recorded locally via flash player.
The application works OK for Firefox and it communicates to CMS without problems, but it does not communicate using Explorer or Chrome browsers. Any suggestion?
Another important point: the application works OK accessing it directly on Explorer or Chrome ( without loading it via Facebook post), so the problem is just when it is accessed via Facebook post.
See the documentation here: https://developers.facebook.com/docs/feed-gaming/
I'm reasonably sure you can't make calls back to the server, you need to configure the SWF via URL parameters
This question is not about how to set up local environment to test Facebook application. Rather I've already set this up with the help of this thread. In short I changed my hosts file and its working great.
But, I've a got a doubt:
Assumption: Everywhere I've read that Facebook server works like a proxy and fetches web-pages, like a web service, from application provider's server and then sends this embedded data to browser.
For testing purposes, I've changed my hosts file like mentioned in above thread. My question is if Facebook server is fetching data from my web server then how come my browser gets this data locally after changing hosts file?
It seems either my assumption is wrong or I am missing something fundamental. Please help. Thanks.
Facebook only acts as a proxy server if you are building an FBML app. If you are building an iFrame app, the request to your application is coming directly from the client browser. You can test this out by actually setting your canvas url to something like http://localhost:8080/ and running your app locally. You will be able to run the application like normal, but obviously only you will be able to use it since it is on localhost.
