Unable to read a property on method 'trackTiming

Having this error: Unable to read a property on method 'trackTiming'
Flash Builder 4.7 + Air 4.0 - iOS

Any idea!?

if (Analytics.isSupported()) {
                Analytics.getInstance().debug = true;
                var analytics:Analytics = Analytics.getInstance();
                var tracker:ITracker = analytics.getTracker("UA-xxxxxxxxx");
                tracker.buildView("MainScreen").track();
            }

Thanks

Same here, though I only seem to get it when I call timing:

ArgumentError: Unable to read a property on method 'TrackData:trackTiming'.

at TimingBuilder/track()[/Users/alessandro.bianco/SkyDrive/Workspace/Personal/ANE-Google-Analytics/source/actionscript/agnostic/src/eu/alebianco/air/extensions/analytics/TimingBuilder.as:47]

Code:

    public function trackLoadTime( name:String, duration:uint, label:String = null, activity:String = 'loading' ):void{
        if( !Analytics.isSupported() ) return;
        var event:ITimingBuilder = googleTracker.buildTiming( activity, duration ).withName( name );
        if( label != null ) event.withLabel( label );
        event.track();
        trace( "Tracked GA Load Time", activity, name, duration, label );           
    }

No issue with IEventBuilder

Any idea!?

It sort of seems to be an issue with the initialization of the ANE. These calls all work if you call them later in the app, but I was calling mine somewhat early-on.

I haven't been able to pin down what the "cut-off" period is, however.

sorry guys for the delay, i will need to do some tests to verify it but i was just looking at the code and i can say you two things:

1. there's no warm-up period, as soon as you get an instance of a tracker you can start using it
2. from the code i can see that the message that @mrfrasier posted is due to not being able to read either the category or interval properties. double check if you're sending null values because that could mess it up
3. @mrfrasier has issues on android but @selimanac reported it to be on iOS. it could be a cross-platform issue but i really want to stress the importance of reporting as many info as possible: platform, version of the extension etc ...

i'll get back to you as soon as i can run some tests

[mrfrasier]

Sorry, I'm developing for both platforms at once, so I didn't think to specify. I tried it this morning and it worked 100% fine on Android. Will publish on iOS now (always a longer process) and see what's up.

Ok, got it to happen again on iOS. Looks like the duration passed was huge (coding issue on my end). So I guess null or values that are too large can cause this:

code:
googleTracker is [object Tracker]

would the duration number be bigger than the int limit? 2,147,483,647?
the API uses a uint which has a bigger limit, but then it might cause an error during the conversion in the native side i guess.
maybe i could change the API to make it a bit more consistent ..

I added a story on trello to keep track of it https://trello.com/c/9u7f8zOK/34-change-timing-traker-api-to-use-int-to-avoid-conversion-issues-with-big-numbers

[selimanac]

Looks like its a new compiler problem.
When i use "-useLegacyAOT no" for standart debug packaging it gives an error: "Having this error: Unable to read a property on method 'trackTiming/trackView/trackSocial'".

When i remove useLegacyAOT and package, dont have any error and it works.

Thanks

[alebianco]

oh yeah, it could be, the AOT compiler is not very reliable yet

i'm not planning to give AOT official support until it's stable but i'll stick a new story to some tests with it. thanks for pointing it out

[mrfrasier]

It shouldn't ever be that big, that was an error in my code. I've now put a check before any calls to stop any big numbers from going in should they happen.

Thanks again!
