Hi, thanks for your contribution! |

@Calinteodor PTAL. @rcidt we already have an external API equivalent on RN SDK, perhaps this could tap into that 🤔 |
|
@saghul can you point me in the right direction? |
|
Here is how a new event was added to the RN SDK: 782d46b You can borrow some inspiration from there I think. |

@saghul the I had to add a new native module to listen to the darwn notifications coming from the Broadcast Extension on the native side, and then forward those notifications via RCTEventEmitter to the JS side. |
|
Sorry, my wires crossed, ignore my previous message. We had a similar situation with ongoing notifications on Android. Since we now have basically 2 ways to do the same thing, we could move the current native handling part to JS so the same implementation works for both. |
|
@saghul that's a fair point |
…moves it into a common screen-share middleware to be used by both native and RN sdks
|
@saghul I made the suggested changes. I moved the screen share event logic out of the external-api middleware and into a common screen-share middleware to be used by both native and RN sdks. |

@rcidt I tested your PR using the sample app below. |
@rcidt I also tested screen-share feature on our end and it seems that some of the changes here broke it. |

Please check this warning
Module ScreenShareEventEmitter requires main queue setup since it overrides constantsToExport but doesn't implement requiresMainQueueSetup. In a future release React Native will default to initializing all native modules on a background thread unless explicitly opted-out of.

Thread 1: "Error when sending event: org.jitsi.meet.TOGGLE_SCREEN_SHARE with body: {\n enabled = 1;\n}. RCTCallableJSModules is not set. This is probably because you've explicitly synthesized the RCTCallableJSModules in ScreenShareEventEmitter, even though it's inherited from RCTEventEmitter."

@Calinteodor thanks for the review. I have tested this using the rnsdk but have not done so with the ios sdk. I'll find some time this week to give it a go and look at these issues. |
Did you test this using the react-native example app, if so what feature is broken? Or did you test using the ios sample app? |
I tested your changes on Jitsi Meet. I mentioned the error above on handleBroadcastStarted. |

@rcidt Ping, are you still interested in pursuing this? |
Seems like the only reason screen share was not working on RNSDK for ios was because the external api is not present, thus no darwin notification events get received by the JS in order to start the web socket.
In the PR I create a dedicated screen share event emitter module for iOS which listens for darwin notification events and forwards them to the JS side.
I made these changes directly within the node_modules in my main project and it is working fine, so I copied the changes into this fork.
