Incoming call make app crashes.

[fedesenmartin]

Hi

I have an issue when the apps get an incoming call. It only happens in one device.But I think is something related with this

• (void)audioRouteChangeListenerCallback:(NSNotification *)notif { if (IPAD) return;

  // there is at least one bug when you disconnect an audio bluetooth headset // since we only get notification of route having changed, we cannot tell if that is due to: // -bluetooth headset disconnected or // -user wanted to use earpiece // the only thing we can assume is that when we lost a device, it must be a bluetooth one (strong hypothesis though) if ([[notif.userInfo valueForKey:AVAudioSessionRouteChangeReasonKey] integerValue] == AVAudioSessionRouteChangeReasonOldDeviceUnavailable) { _bluetoothAvailable = NO; } AVAudioSessionRouteDescription *newRoute = [AVAudioSession sharedInstance].currentRoute;

  if (newRoute) { NSString *route = newRoute.outputs[0].portType; LOGI(@"Current audio route is [%s]", [route UTF8String]);

  _speakerEnabled = [route isEqualToString:AVAudioSessionPortBuiltInSpeaker];
  if (([[AudioHelper bluetoothRoutes] containsObject:route]) && !_speakerEnabled) {
      _bluetoothAvailable = TRUE;
      _bluetoothEnabled = TRUE;
  } else {
      _bluetoothEnabled = FALSE;
  }
  NSDictionary *dict = [NSDictionary
      dictionaryWithObjectsAndKeys:[NSNumber numberWithBool:_bluetoothAvailable], @"available", nil];
  [NSNotificationCenter.defaultCenter postNotificationName:kLinphoneBluetoothAvailabilityUpdate
                                                    object:self
                                                  userInfo:dict];

  } }

Here is the crashLog ->

Hello,

at what lines does it crash ?

Thanks

[fedesenmartin]

LINE 2608 (LinphoneManager.m) -> NSString *route = newRoute.outputs[0].portType;

[ghost]

Does it happen on every call ? Can you post logs ?

Thanks

[fedesenmartin]

It happened in every call ,

I make a new branch with a change in LinphoneManager.m

if (newRoute) { // this

if (newRoute && [newRoute.outputs count]>=1) {// for this

And now the first call doest ring,but the app dont crash but it flash the screen, and the next calls are working fine without having to restart app.

I have the same bug too on iOs 12

[HuangLiang-Jun]

same issue on iOS12,I used the Linphone APP have the same issue too.

Looks like a ios12 bug. AVAudioSession fails to fill its properties. With a break point everything works fine but without breakpoints it just crash. I have put an if check for currentroute property then crashed occured inside iOS not in application code. Looks like iOS 12.2 does not have this problem. Btw I did this with totally a different application.
