answerCall event not getting called on app killed state iOS

[shashankmeddo]

Hi,

My app works fine on iOS when the app is in background or foreground ho ever
when app is in killed state then none of the event is getting called
I am mainly interested in
answerCall Event of RNCallKeep

[shashankmeddo]

I also would like to know which method opens the app
when user answers the call

How do you mean @shashankmeddo ? What are you using to start up the app? a push notification? a voip push? are you displaying the incoming call in native land due to the recent ios13 changes... you'll need t give us some more information for us to help you

If you are using react-native-voip-push-notification to start the app, this pull request helped me to fix the same issue: react-native-webrtc/react-native-voip-push-notification#52

@danjenkins I have added 'answerCall' eventListener in my App.js in which I am navigating user to a video call screen and the case is -
App is in killed state and VOIP push arrives. So when I answered the call, it opens my application and nothing happened. That event didnt called.
But when the app was in foreground or in active state, 'answerCall' event fired and it navigate to video screen but when the app was in killed state, that event didnt fired.

I'm having this same issue on android. Does anyone have any suggestions?

Same issue here on IOS 13.3, iphone 8 (Real device), react-native 0.65.1

When i open the app for the first time everything runs ok on the background.
When kill the app process, then re-run, he does'nt work on the background.

If i found an error code i will provide one.

Maybe this is a error code related:

Can't end BackgroundTask: no background task exists with identifier 17 (0x11), or it may have already been ended. Break in UIApplicationEndBackgroundTaskError() to debug.

Same issue but in my case displayincoming event is fired and show incoming screen, but when I press answer button nothing happen, answer event didn't be occured

It happened for the first time when voip push launch the app after killed

Does anybody have an update about this issue?Any help or something? I'm stuck on this problem :(

[CaptainJeff]

@willnaoosmit nope. Still having the same issue. I only have it on older iphones though. Newer ones seem fine. I can't figure out why that is

By "Older" you mean what iPhone versions?
I'm facing this issue on a real iPhone 8 device, and a iPhone 11 simulator, if I'm not wrong.

Also, taking advantage of you here, do you have a problem with the app doesn't working on foreground or background when installed by the App store itself?

I uploaded him using the app store and it simply doesn't work even the first time :(

@willnaoosmit

So all of these were tested on real devices. It works fine on multiple iphone X's and iphone XR's (various iOS 13's) and then it works fine on the foreground for iPhone SE (13.3.1) / iPhone 7 (11.2.5) / iPhone 7 (12.4) but not the background

Edit: Its worth noting I had the same experiences testing on development and production

Make sure:

• use voip push ( the formal way to bring your app alive for callkit actions )
• add the answerCall event on the very beginning of your app entry( eg: the top of index.js or app.js ), ASAP

Personally, I didn't face this issue ( answerCall event not fired issue ), so I can not reproduce it to test something like #169

If you did the above and still have the same issue, give #169 a try

[zxcpoiu]

Also, you may try to invoke completion() later.
Choose one of the method below:

Method 1 ( react-native-callkeep )

Use #191 to invoke completion() automatically on native side right after reportNewIncomingCall are done with it's job

Method 2 ( react-native-voip-push-notification )

If you use RN voip push

You can use react-native-webrtc/react-native-voip-push-notification#52 to invoke completion() on the JS side manually after you've done your own customization.
