Proximity sensor event not being fired

[tophed]

Hi,

I recently starting using this library with a project created with react native init. I manually linked the library per the instructions.

I noticed the proximity sensor functionality was not working as expected. After calling InCallManager.start(), the screen would not turn off when something was close to the sensor.

I checked the code in RNInCallManager.m and found the function for starting the proximity sensor, and noticed _currentDevice.proximityMonitoringEnabled set to NO:

- (void)startProximitySensor
{
    if (_isProximityRegistered) {
        return;
    }

    NSLog(@"RNInCallManager.startProximitySensor()");
    // _currentDevice.proximityMonitoringEnabled = YES;
    _currentDevice.proximityMonitoringEnabled = NO;
    
    // --- in case it didn't deallocate when ViewDidUnload
    [self stopObserve:_proximityObserver
                 name:UIDeviceProximityStateDidChangeNotification
               object:nil];

    _proximityObserver = [self startObserve:UIDeviceProximityStateDidChangeNotification
                                     object:_currentDevice
                                      queue: nil
                                      block:^(NSNotification *notification) {
        BOOL state = _currentDevice.proximityState;
        if (state != _proximityIsNear) {
            NSLog(@"RNInCallManager.UIDeviceProximityStateDidChangeNotification(): isNear: %@", state ? @"YES" : @"NO");
            _proximityIsNear = state;
            [self sendEventWithName:@"Proximity" body:@{@"isNear": state ? @YES : @NO}];
        }
    }];

    _isProximityRegistered = YES;
}

I uncommented the line setting it to YES and commented the line setting it to NO, and it starting working after rebuilding. However it now gives this warning:

-[UIApplication setExpectsFaceContact:inLandscape:] must be used from main thread only

I'm wondering if this is the actual fix or if I am missing something. Thanks!

try to import NativeModules and put the line in your JS code NativeModules.InCallManager.addListener('Proximity');

@tophed what did you end up doing here? The NativeModules solution above doesn't seem to work for me
