Video-Web | Vue2.0实现的手机端视频资源网 - Vue2 | State Container library

I am trying to implement video calling feature in react native app. I have used React native twilio video webrtc. I have implemented the same and got it working.

I don't exactly know the flow of Video calling in mobile apps. The flow which I am using for video calling is as follows:

1. User 1 taps to call User 2
2. Your app generates a unique name for a Room. Perhaps a combination of the two user's IDs.
3. User 1 connects to Room with generated unique name
4. Using FCM, send message of high priority with the unique name of the Room and token to User 2
5. User 2 to receives notification and you display a ringing UI(even when the app is killed and phone is locked)
6. User 2 accepts and connects to the same Room

Now I am stuck on point 5. I am sending the FCM notification(which shows up in tray (edit: now using voip notif) to user2 and now I need to show ringing UI on user2's mobile even if the app is killed and phone is locked. How can I achieve this?

I guess there is a package called react-native-callkit, which I should be using along with PushKit for the same. But the problem is with android flow. PushKit and CallKit is not supported in android. So, when app is in killed state the notification appears I need to grab the control and display ringing UI and wake the screen if the phone is locked and app is killed.

Some Confusions

Is there any special type of push notification which doesn't get displayed in the tray? (edit: data messages and VOIP notif I guess)

Is there any other package than react-native-callkit(for displaying ringing UI) which can be used for both android and ios?

I have integrated a webcam video capture into a Shiny app using RecordRTC and JavaScript. That works great and I can access and store my videos in a JavaScript variable named "video.blob". However, I struggle with exporting that file into my app's shiny directory upon pressing a "btn-save-recording" button.

I have tried to pass the blob to shiny as suggested here: https://shiny.rstudio.com/articles/communicating-with-js.html

I have used twilio-video:1.19.2 in angular 8.

I have implemented functionality of one-to-one video call.

Below is my code i use to enable/disable video.

I'm currently trying to build my React Native project (using ExpoKit and several native modules) for Android on a Mac running Mojave. It's working fine on iOS. However, I'm getting Could not find react-native.jar when running react-native run-android. It's looking for a react-native-33.0.0.jar file in file:/Users/username/Documents/Projekte/appname/app/node_modules/expokit/maven/com/facebook/react/react-native/33.0.0/, however, it's not there.

This is the output of react-native info:

So I am trying to setup closed captions for chromecast using the default chrome sender app, according to the docs this should be possible, as seen here. I can't figure out why my code does not work. It is almost identical to the provided sample code.
The snipper probably does not work because it's too sandboxed, see it here in a normal html page: Click!
One first should connect their chromecast using the top button, and then click on "load video".

My code:

I am facing an issue, Whenever I try to build using react-native run-android, the build fails with the following error.

\?\E:\projects\deets-mobile-cp\android\app\build\intermediates\manifests\full\release\AndroidManifest.xml:88: AAPT: No resource identifier found for attribute 'appComponentFactory' in package 'android'

FAILURE: Build failed with an exception.

• What went wrong: Execution failed for task ':app:processReleaseResources'.

  Failed to process resources, see aapt output above for details.

I have researched about the error but failed to resolve it. Whats going wrong I can't figure out. I am using gradle v3.1.2.

Does anybody have idea whats going wrong

I'm building a React-Native app using react-native-twilio-video-webrtc and I'm having trouble configuring the iOS app with pods. I followed the integration steps for iOS given in the tutorial (link above) and got this error when running pod install :
