Where does Jitsi Mobile create RTCPeerConnection object? - react-native

I’m trying to find the code where the addresses from the STUN server are received/collected from react-native and when Jitsi creates RTCPeerConnection object. My purpose is, I want to pass along additional parameters to RTCPeerConnection.js inside react-native-webrtc since I have our own customized webrtc and need to set some value there. Does anyone know which part of Jitsi takes the value from react-native and creates RTCPeerConnection object? I already try to take a look at here but seems react-native does not use this code.
Thank you for help

How to setup connection between React Native app and Thingspeak (cloud service)?

I'm a beginner in react native and I'm working on a mobile app for school. Within it, I need to send and receive data (draw graphs) from the cloud. We use cloud services from Mathworks - Thingspeak. Would you please advise me on how to start this communication? Is it necessary to set this communication on every screen where graphs will be displayed or send data? Is it possible to use write & read API keys for this task?
Thank you for every answer
You can use REST API for communication,

For write: https://www.mathworks.com/help/thingspeak/writedata.html
There are example requests on both pages.
You don't need to install a separate package, you can do it with fetch

How is anyone processing payments with React Native apps at present?

Trust me when I say I've tried every single solution people are currently downloading. tipsi-stripe, react-native-payments, react-native-paypal, you name it.
Every single guide says to link the library using link. Or automatically using yarn/npm. I've tried both ways, doesn't work. The new React Native version is certainly preventing this, and all the npm packages are failing. It seems no one can update the packages to work with react native yet.
If this is the case, how is anyone at all processing payments in react native? There doesn't appear to be any workable option here. Going to have to cancel my client's project due to impossible needs, simply payments.
I would think the best solution is to have a server or webservice that calls an API like PayPal v2/checkout/orders, to set up and capture a transaction. See "Create Order" and "Capture Order" here: https://developer.paypal.com/docs/business/checkout/server-side-api-calls/#server-side-api-calls
Then, for the approval flow, you can open a secure browser view to the approval_url the create call returns, having set the return_url in your creation to be a deeplink back to your app, which when opened immediately calls your server or webservice to do the capture and respond with success/failure.

Pass encrypted parameters with Deep Linking

I am new to react-native and I am trying to open another app from my react-native application(kind of app launcher). I understand that deep linking must be implemented on the app that I am trying to open, but in addition to that, I want to pass parameters(probably encrypted) from my react-native application so that another app can use those parameters. The parameter that I want to pass is sensitive and hence I want to keep it encrypted. So far I am not able to find anything related to the same. Is there a way to achieve the same.

How to trigger an UI action when the app is closed in React Native?

Apologies if my question is already answered in any other ways. I am very new to react-native with no knowledge of android or java.
I am trying to make a video conferencing app with react native. I used Agora for video calling and linked it with socket.io and react-native-callkeep for real time experience.
Now i am stuck in a situation where i have to make the app functional when someone is calling and the app is ""Closed"". Something like Whatsapp. I thought of implementing Firebase Cloud Messaging for push notification. And though it will open the application in someway. But the application opens when user opens the notification.
Can anyone please help me with any of the following or better ideas:
1. Keep the socket io open even when app is closed
Or 2. Open my application with incoming push notification (Without Opening It)
Please avoid abstruct answers as i am very new in this sector. I really appreciate the help. Thank you.
I think the second method is the way to go you can also look at this library called react-native-callkeep I think it fits your use-case as well.

Voice call connection routing React-Native

I am trying to build an application which works this way: I as a user want to start a call with another user. The way I want the connection be made is by random. So it will connect to one of the many clients out there by random. Also when other clients try to make a call, it should connect to another random client and so on. I want those phone calls be made via application(such as WhatsApp) not as a phone call.
Now, the question is; is Twilio a good approach for this purpose?
If yes can you tell me which of their feature would fit my app the best?
Thanks for any suggestions!
Twilio developer evangelist here.
I can answer that Twilio would be a good approach for you to do this within your own application. I'd recommend using Twilio Video to build this as it allows cross platform communication via audio or video (in your case, you may not need the video, but this will give you the best audio quality).
As an example, my colleague Dominik built a video roulette application. It is the case that the interface was built in JavaScript for the web, but the idea would be the same for a native app. The code for the server side part of the application should give some insight into how to connect random pairings.
It's also possible to integrate Twilio Video with CallKit and Connection Services so that you can make outbound calls to other devices that ring like a real incoming call.
