i have a problem when answering call on via callkit ui if my app is in lockscreen and killed state. I am currently using skyway for the audio and video call
issue description
this issue doesn't happen on ios 15 version
I realise this is a little late but we ran in to a similar issue and managed to solve it by making sure the device is unlocked before fulfilling the CXAnswerCallAction.
The code looked like this:
func provider(_ provider: CXProvider, perform action: CXAnswerCallAction) {
checkUnlockedAndFulfill(action: action, counter: 0)
}
private func checkUnlockedAndFulfill(action: CXAnswerCallAction, counter: Int) {
if UIApplication.shared.isProtectedDataAvailable {
action.fulfill()
} else if counter > 180 { // fail if waiting for more then 3 minutes
action.fail()
} else {
DispatchQueue.main.asyncAfter(deadline: .now() + 1) {
self.checkUnlockedAndFulfill(action: action, counter: counter + 1)
}
}
}
Hopefully this helps.
Hi Radther,thanks for your answer. I'm trying to implement this on flutter. Do you know where should I put that code? Could AppDelegate.swift be the right place? Thanks
This seems to help me when my app is locked and in the background, but when locked + killed the app doesn't start up once the call has been answered and unlocked.
I've had this bug for over a year. THANK YOU! Thought I was going crazy. This worked perfectly.
Hello Team
Facing same issue tried above solution not work for me please help.
Hi there, I got this problem even IOS < 16, any new solution now?
Hello, maybe I'm a bit late to the party but what worked for me when the app is killed and user delays unlocking for seconds is @Radther answer but adding UIApplication.shared.applicationState == .active as AND condition
func provider(_ provider: CXProvider, perform action: CXAnswerCallAction) {
checkUnlockedAndFulfill(action: action, counter: 0)
}
private func checkUnlockedAndFulfill(action: CXAnswerCallAction, counter: Int) {
if UIApplication.shared.isProtectedDataAvailable,
UIApplication.shared.applicationState == .active // <-- This
{
// Add your videocall view to view hierarchy here, not before
action.fulfill()
} else if counter > 30 { // Timeout in seconds
action.fail()
} else {
DispatchQueue.main.asyncAfter(deadline: .now() + 1) {
self.checkUnlockedAndFulfill(action: action, counter: counter + 1)
}
}
}
