Hi @puneetk207

Can you provide the backtrace of the crash? you can get the log by typing bt all in the Xcode debugger. It would be helpful to get the insights about what might have caused the crash.

Thanks. -bobie

Thanks for the SDK log @puneetk207 but from the log it doesn't really indicate what caused the crash. Please use the bt all command to dump the backtrace so we can help you identify the root cause of the crash.

puneetk207 commented 4 years ago

@bobiechen-twilio I am not using Xcode. I am building an iOS app on Xamarin platform using Twilio.Voice.iOS.XamarinBinding nuget package. Please let me know if there is any command which help you out here.

bobiechen-twilio commented 4 years ago

Hi @puneetk207 There are some material about debugging the iOS native crash with Xamarin environment: https://docs.microsoft.com/en-us/xamarin/mac/deploy-test/debugging-native-crash Device (crash) logs can also be extracted using Xcode: https://docs.buddybuild.com/troubleshooting/getting_device_logs_from_xcode.html

bobiechen-twilio commented 4 years ago

Thanks @puneetk207 this is exactly what we need.

Now it seems the crash was caused by something wrong in the SDK, can you use the logging API to enable trace level SDK log? (you might need to find the mapped API in the Xamarin plugin)

    [TwilioVoice setLogLevel:TVOLogLevelTrace];
    [TwilioVoice setLogLevel:TVOLogLevelTrace module:TVOLogModuleCore];
puneetk207 commented 4 years ago

Hi @bobiechen-twilio Yes i know that how to use this two commands.

puneetk207 commented 4 years ago

Hi @bobiechen-twilio

TwilioVoice.LogLevel = TVOLogLevel.Trace; TwilioVoice.SetLogLevel(TVOLogLevel.Trace, TVOLogModule.Core);

This i get using two commands :---

bobiechen-twilio commented 4 years ago

Thanks @puneetk207! While I am checking the log, does this happen every time you try to make an outgoing call?

puneetk207 commented 4 years ago

yes every time @bobiechen-twilio

bobiechen-twilio commented 4 years ago

Hi @puneetk207

I have created a ticket for tracking this crash. One more question - what is the device you use when this happens? asking because it seems to happen when the SDK is retrieving platform information.

Thanks. -bobie

puneetk207 commented 4 years ago

@bobiechen-twilio I am running it on simulator (iOS 13.6) and do not use any physical device

puneetk207 commented 4 years ago

@bobiechen-twilio any update on this ? any workaround you can suggest ?

puneetk207 commented 4 years ago

@bobiechen-twilio any workaround for now atleast ?

bobiechen-twilio commented 4 years ago

Hi @puneetk207

Does this happen on real iOS devices in your environment? also do you know if this happen to a specific device model simulator or all of them?

We have tried the same in our environment but couldn't reproduce the same crash. Is it possible that this is caused by the Xamarin API binding? Can you open the quickstart with Xcode and see if this is happening?

Thanks, -bobie

puneetk207 commented 4 years ago

@bobiechen-twilio yes all the simulators but works on real device. It is same issue what i found while googling (see below) https://github.com/twilio/twilio-voice-ios/issues/13 So i changed the twilio sdk to 3.1.1 and it is working on simulator now.

bobiechen-twilio commented 4 years ago

Hi @puneetk207 thanks for the update.

For best compatibility, especially with the latest iOS, we still recommend using the latest version of the Voice SDK. From the crash backtrace it seems that some of the platform information or the system API might not be available with the simulators in your environment.

To help us further diagnose the issue, could you use the follow code in your app and let us know the contents of the bundleInfo variable? (you might have to find the .m file in the native Xcode project)

NSDictionary *bundleInfo = [[NSBundle mainBundle] infoDictionary];
NSLog(@"%@", bundleInfo);

Thanks, -bobie

puneetk207 commented 4 years ago

@bobiechen-twilio where to place this code while making calls or at start of app ?

bobiechen-twilio commented 4 years ago

Hi @puneetk207

At the start of app works.

puneetk207 commented 4 years ago

@bobiechen-twilio What i found after placing this code :--

{ BuildMachineOSBuild = 19G2021; CFBundleDisplayName = XXXX; CFBundleExecutable = "XXXX"; CFBundleIcons = { CFBundlePrimaryIcon = { CFBundleIconFiles = ( AppIcon20x20, AppIcon29x29, AppIcon40x40, AppIcon60x60 ); CFBundleIconName = AppIcon; }; }; CFBundleIdentifier = "XXXXX"; CFBundleInfoDictionaryVersion = "6.0"; CFBundleName = XXXX; CFBundleNumericVersion = 0; CFBundlePackageType = APPL; CFBundleShortVersionString = "XXXX"; CFBundleSignature = "????"; CFBundleSupportedPlatforms = ( iPhoneSimulator ); CFBundleVersion = "XXXXXX"; DTPlatformName = iphonesimulator; DTSDKName = "iphonesimulator13.6"; LSRequiresIPhoneOS = 1; MinimumOSVersion = "8.0"; NSMicrophoneUsageDescription = "This app needs to use your microphone"; UIBackgroundModes = ( audio, voip ); UIDeviceFamily = ( 1, 2 ); UILaunchStoryboardName = LaunchScreen; UISupportedInterfaceOrientations = ( UIInterfaceOrientationPortrait ); UIUserInterfaceStyle = Light; "com.xamarin.ios" = { Version = "13.18.2.1 (d16-6: 29c4ea731)"; }; }

bobiechen-twilio commented 4 years ago

Thanks for the update @puneetk207. I am not sure if it's the way Xamarin bindings handle the contents of the bundle information, but there are a some fields missing that the SDK uses. For better iOS compatibility we still recommend using the latest Voice SDK since you mentioned that it works fine on real devices in your environment.

deftsoftiphone commented 4 years ago

This issue is occurring on making a call from device as well it is not only simulator issue. I am having iPhone 8+ with iOS 12.2 and it is crashing with giving error:

*** Terminating app due to uncaught exception 'TVOAudioDeviceMustBeSetBeforeMediaStackSetup', reason: 'WebRTC does not allow updating the audio device once the media stack is created (i.e once a track is created or memory allocated for previously created call or connect option is not deleted). You should provide the audio device to SDK prior to creating the tracks.'

However there is no previous audio device in media stack but still it is giving same error

I am using the latest Twilio version 6.0.0. It was working fine before but now it is giving me an error

bobiechen-twilio commented 4 years ago

Hi @deftsoftiphone

The exception message you saw is from a different cause than the original issue reported here. We are happy to continue our discussion in #392.

bobiechen-twilio commented 4 years ago

Hi @puneetk207, I am closing the issue for now since the latest SDK is functioning as expected on actual devices (and on simulators in our environment). Please feel free to reach out to the team if you need further assistance.

Cheers, -bobie

deftsoftiphone commented 4 years ago

@puneetk207 are you able to fix this issue ?

puneetk207 commented 4 years ago

@deftsoftiphone yes i fixed this using old release on simulator.
