iOS screen broadcast freezes after the app is moved to the background for a few minutes. #1641

harshmdr · 2024-07-30T01:13:19Z

After moving background, open any app like gmail etc and then leave it for some seconds and now screen streaming is frozen in IOS. Once you back into foreground, it is working again.

Any suggestion/solution here?

It is working on debug mode while developing but not for release app.

I will look into that.

Thank you @vendroid12

A year ago, I faced this issue and after investigations, I realized that starting iOS CallKit is necessary because it keeps your app as a high priority.

harshmdr · 2024-07-31T03:17:50Z

Can you please explain a little bit more like what steps do I need to do? @lambiengcode
I just need to broadcast IOS screen on all other apps.
Thank you

When broadcasting my phone screen, if I switch to other apps for a few minutes without starting CallKit, the system assumes my app is using unnecessary energy. I noticed that apps like Jitsi and Google Meet start CallKit to avoid this issue. After implementing CallKit in my app, it worked correctly as well.

You can use: https://pub.dev/packages/flutter_callkit_incoming and implement some code in native iOS:

import Flutter
import UIKit
import waterbus_callkit_incoming

public class WaterbusSdkPlugin: NSObject, FlutterPlugin {
  var uuidCall: String = ""

  public static func register(with registrar: FlutterPluginRegistrar) {
    let channel = FlutterMethodChannel(name: "waterbus-sdk/native-plugin", binaryMessenger: registrar.messenger())
    let instance = WaterbusSdkPlugin()
    registrar.addMethodCallDelegate(instance, channel: channel)
  }

  public func handle(_ call: FlutterMethodCall, result: @escaping FlutterResult) {
    switch call.method {
    case "getPlatformVersion":
      result("" + UIDevice.current.systemVersion)
      break
    case "startCallKit":
      let arguments = call.arguments as? [String: Any] ?? [String: Any]()
      let uuidCallPartner = NSUUID().uuidString
      self.uuidCall = uuidCallPartner

      let nameCall = arguments["nameCaller"] as? String ?? "Waterbus"
      var info = [String:Any?]()
      info["id"] = uuidCallPartner
      info["nameCaller"] = nameCall
      info["handle"] = "0123456789"
      info["type"] = 1
      
      SwiftFlutterCallkitIncomingPlugin.sharedInstance?.startCall(waterbus_callkit_incoming.Data(args: info), fromPushKit: true)
      result(true)
      break
    case "getCurrentUuid":
      result(self.uuidCall)
      break
    default:
      result(FlutterMethodNotImplemented)
    }
  }
}

After call connected, call startCallKit. Take a look at: https://github.com/waterbustech/waterbus-flutter-sdk/blob/migration/v2/ios/Classes/WaterbusSdkPlugin.swift

Thanks @lambiengcode

harshmdr · 2024-07-31T03:43:58Z

I am not using incoming and outgoing calls in our app, so you mean we just need to show that we are using call, Is that right?
@lambiengcode

lambiengcode · 2024-07-31T03:50:07Z

My app does not use incoming calls. I implemented CallKit solely for screen sharing. Is is clear?

harshmdr · 2024-07-31T10:28:30Z

@lambiengcode Thanks, now your solution is working for me.
I have used https://pub.dev/packages/flutter_callkit_incoming , no need to add native code.

Future<bool> startOutGoingCall() async {
    if (Platform.isIOS) {
      try {
        // Generate a UUID
        String uuid = const Uuid().v4().toString();
        // Ready Params
        CallKitParams params = CallKitParams(
            id: uuid,
            nameCaller: "harsh tyagi",
            handle: '0123456789',
            type: 1,
            extra: <String, dynamic>{'userId': 'harshtyagimdr'},
            ios: const IOSParams(
                iconName: "Logo", // ios/Runner/Assets.xcassets/Logo.imageset
                handleType: 'generic',
                audioSessionActive: false,
                configureAudioSession: false));

        await FlutterCallkitIncoming.startCall(params);

        callListener = FlutterCallkitIncoming.onEvent.listen((event) {
          switch (event!.event) {
            case Event.actionCallStart:
              print("call started");
              break;
            case Event.actionCallEnded:
              print("call Stopped");
              break;
            default:
              break;
          }
        });
        setState(() {
          currentUuid = uuid;
        });
        return true;
      } catch (e) {
        showToast("Something went wrong! Please start again", isError: true);
      }
    }
    return false;
  }

  Future<void> stopOutGoingCall() async {
    if (currentUuid != null && Platform.isIOS) {
      try {
        await FlutterCallkitIncoming.endCall(currentUuid!);
        setState(() {
          currentUuid = null;
        });
        callListener?.cancel();
      } catch (e) {
        print("Error while stop outgoing call: $e");
      }
    }
  }
