Google Analytics missing sample & possibly not working

[jpancik]

Hello,

I have a problem with google analytics. My tracking code is not sending any data (tested with realtime and also checked on the next day). It worked in previous versions and I have updated my libs properly.

As there is no sample to check against, I will post my code here and if I'm doing something wrong please point it out. Maybe somebody could share their working tracking code?

Thanks.

public class IOSAnalyticsClient implements GoogleAnalyticsClient {
    private String id;

    private GAIDefaultTracker tracker;

    public IOSAnalyticsClient(String id) {
        this.id = id;
    }

    @Override
    public void startSession() {
        GAI.getSharedInstance().setDryRun(false);
        GAI.getSharedInstance().setDispatchInterval(20.0);

        tracker = GAI.getSharedInstance().getTracker(id);
    }

    @Override
    public void stopSession() {
        try {
            tracker.dispose();
        } catch (Throwable e) {
            e.printStackTrace();
        }
    }

    @Override
    public void trackEvent(String category, String action, String label, long value) {
        tracker.send(GAIDictionaryBuilder.createEvent(category, action, label, NSNumber.valueOf(value)).build());
    }

    @Override
    public void trackPageView(String name) {
        tracker.set("kGAIScreenName", name);
        tracker.send(GAIDictionaryBuilder.createAppView().build());
    }

    @Override
    public void trackTiming(String category, long timeInMilliseconds, String name, String label) {
        tracker.send(GAIDictionaryBuilder.createTiming(category, NSNumber.valueOf(timeInMilliseconds), name, label).build());
    }

    @Override
    public void trackException(String description, Throwable t, boolean fatal) {
        tracker.send(GAIDictionaryBuilder.createException(description, fatal).build());
    }

    @Override
    public void dispatch() {
        //System.out.println("dispatching");
        GAI.getSharedInstance().dispatch();
    }
}

[milos1290]

Yeah, i trying everything also, and its not working. Last version i've used was working correctly.

[BlueRiverInteractive]

@milos1290 @jpancik I have never used this binding myself but could you check the content of each NSMutableDictionary you are sending? Just call System.out.println(GAIDictionaryBuilder.createAppView().build()); or similar. I assume during conversion to the new bindings something went wrong and maybe these dictionaries are empty now.

[jpancik]

Okey, I've tried in my tracking event code

System.out.println(GAIDictionaryBuilder.createEvent(category, action, label, NSNumber.valueOf(value)).build());

It printed things like:

{
    "&ea" = Debris;
    "&ec" = Experience;
    "&el" = Vase;
    "&ev" = 0;
    "&t" = event;
} 

so I guess this works properly?

[BlueRiverInteractive]

Ok this is interesting. You are also sure that GAI.getSharedInstance().dispatch(); gets called? Otherwise it seems like the binding is working as expected. Maybe it's a problem that dispatch is called from the wrong thread? The facebook binding don't really work, if we don't make the calls from the main thread. You could try to wrap your Analytics calling code inside this:

NSOperationQueue.getMainQueue().addOperation(new Runnable() {
    @Override
    public void run () {
        // your analytics code like dispatch()...
    }
});

[jpancik]

I've tried this:

@Override
public void trackEvent(String category, String action, String label, long value) {
    NSOperationQueue.getMainQueue().addOperation(new Runnable() {
        @Override
        public void run () {
            tracker.send(GAIDictionaryBuilder.createEvent(category, action, label, NSNumber.valueOf(value)).build());
            GAI.getSharedInstance().dispatch();
        }
    });
}

but still no go. Any further things I can try?

[StevenGlrz]

I simply do this and everything works fine

in the main method

    GAI.getSharedInstance().setDispatchInterval(20);
    GAI.getSharedInstance().setDefaultTracker(GAI.getSharedInstance().getTracker("trackingidhere"));

and in method where I initiate UI things

        UIWindow trackWindow = new UIWindow(new CGRect(0, 0, 0, 0));
        GAITrackedViewController trackedViewController = new GAITrackedViewController();
        trackedViewController.setScreenName("Game");

        trackWindow.setRootViewController(trackedViewController);
        trackWindow.makeKeyAndVisible();

Tell me if this works for you

[jpancik]

Please tell me more about the UI part.

rootViewController = UIApplication.getSharedApplication().getKeyWindow().getRootViewController();

this is how I acquire root view controller from libgdx, replacing it with GAITrackedViewController would not work I think.

this is my whole didFinishLaunching code for libgdx game:

@Override
    public boolean didFinishLaunching(UIApplication application, NSDictionary<NSString, ?> launchOptions) {
        boolean result = super.didFinishLaunching(application, launchOptions); 

        rootViewController = UIApplication.getSharedApplication().getKeyWindow().getRootViewController();

        /* here I removed some code where I create some banner ads */   

        rootViewController.getView().addSubview(banner1);
        rootViewController.getView().addSubview(banner2);

        return result;
    }

[StevenGlrz]

I create the view controller when create() is called in the LibGDX application listener. You don't have to modify the view controller that LibGDX has, just create a new one as I posted. I'm not sure if that leads to any issues, but I haven't ran into anything so far.

[jpancik]

I'm sorry, I don't follow. Could you possibly post code of the whole function? You can ofc remove parts that are irrelevant.

[StevenGlrz]

The code I posted that creates the GAITrackedViewController is created in the create() method that LibGDX calls when the app first starts. Sorry if I'm not being clear enough, but if you're using LibGDX, then you should know where create() is being called at.

[jpancik]

Well, the thing I don't understand is this - in create() method I can't call any iOS platform specific code, unless I implement a method in my interface which calls platform specific code. So I'm supposed to do that?

[animvs]

Hello guys. I'm suffering from this exactly problem. I've also tried this code after initializing my tracker:

    UIWindow trackWindow = new UIWindow(new CGRect(0, 0, 0, 0));
    GAITrackedViewController trackedViewController = new GAITrackedViewController();
    trackedViewController.setScreenName("Game");

    trackWindow.setRootViewController(trackedViewController);
    trackWindow.makeKeyAndVisible();

No data being received although. I'm using the ROBOVM's last version.

Any ideas ? Thanks!

[StevenGlrz]

Hmm, that's odd. Try running it on the main thread using the code that BlueRiverInteractive posted earlier in this post.

[zino78]

Hi!

For me isnt working analytics for me too :(

I dont understand how bindings work exactly, but i see something, what i dont understand.

The GAIDefaultTracker class has an empty send method. I think this method dont call the native ios method. In the earlier version the gaitrackerimpl class send method call the native method.

Maybe that is the problem?

My program work fine, but dont send any data to analytics.

Thanks for help!

Z.

[animvs]

Ok, here is the output from builder.build():

{
    "&t" = appview;
    "LEVEL 1-1" = "&cd";
}

[BlueRiverInteractive]

@zino78 You could be onto something. I just pushed a basic implementation of the GAIDefaultTracker. I'm not sure if this does anything (haven't used this binding myself yet) but can you please try if this works for you? Maybe you need to explicitly use the GAIDefaultTracker class via setDefaultTracker().

[zino78]

Thanks a lot! I try it in this eveneing! After it, i write the result. :)

[animvs]

OK, i got this exception from the new build:

Exception in thread "main" java.lang.UnsatisfiedLinkError: @Bridge method      org/robovm/bindings/googleanalytics/GAIDefaultTracker.$m$send$(Lorg/robovm/bindings/googleanalytics/GAIDefaultTracker;Lorg/robovm/objc/Selector;Lorg/robovm/apple/foundation/NSDictionary;)V not bound

[zino78]

Hi! I haven't yesterday time to try the new code, but today i try it!

[animvs]

@zino78 , have youe been able to test it yet ?

[zino78]

Sorry, i don't have time, but today i try it. It make a class castexcpetion, but i don't know why.

java.lang.ClassCastException: org.robovm.bindings.googleanalytics.GAIDefaultLogger cannot be cast to org.robovm.objc.ObjCObject

I try to understand it :)

[animvs]

Thats because GAIDefaultLogger should inherit from NSObject class. You can either change GAIDefaultLogger by yourself (make it extends NSObject) or just don't use it since it is not a required class

[windlord0408]

After updarage code, i got this error: java.lang.UnsatisfiedLinkError: @Bridge method org/robovm/bindings/googleanalytics/GAIDefaultTracker.$m$send$(Lorg/robovm/bindings/googleanalytics/GAIDefaultTracker;Lorg/robovm/objc/Selector;Lorg/robovm/apple/foundation/NSDictionary;)V not bound at org.robovm.bindings.googleanalytics.GAIDefaultTracker.$m$send$(Native Method) at org.robovm.bindings.googleanalytics.GAIDefaultTracker.objc_send(GAIDefaultTracker.java) at org.robovm.bindings.googleanalytics.GAIDefaultTracker.send(GAIDefaultTracker.java) Please help me to fix it. Thanks alot

[animvs]

Same here... Anyone got any clue on this ?

[BlueRiverInteractive]

I'm trying to fix this but I need some help.

1. Did it work with the first binding version long time ago? 1.1 If so, can you point me to the commit where it still did work?
2. How is the Google Analytics binding supposed to be used? 2.1 Can you provide me a really basic sample code?

[animvs]

@BlueRiverInteractive , thanks for your time.

1. I had not used the bindings before; when i got to it, it was [apparently] not working; it does compiles before the last commit, but did not send any data.
2. Im not sure i got your point here, but this is how the analytics SDK should be implemented on iOS: https://developers.google.com/analytics/devguides/collection/ios/v3/

2.1 Ok, im building a simple prototype, will send it to you tomorrow.

[windlord0408]

Hi @BlueRiverInteractive, thanks for your answer. I have some information:

1. My project worked fine with older binding version. 1.1 Here's the old version I mentioned above: https://github.com/BlueRiverInteractive/robovm-ios-bindings/tree/ceee584865bfb6db7f2436e5034d22c47eb7a930/google-analytics/src/org/robovm/bindings/googleanalytics 2.2 This's simple class use to call Google Analytics binding:

public class RobovmGoogleAnalytics extends GoogleAnalytics {

private static RobovmGoogleAnalytics instance;

public static RobovmGoogleAnalytics getInstance() {
    if (instance == null) {
        instance = new RobovmGoogleAnalytics();
    }
    return instance;
}

GAIDefaultTracker tracker;

private RobovmGoogleAnalytics() {
    GAI.getSharedInstance().setTrackUncaughtExceptions(true);
    GAI.getSharedInstance().setDispatchInterval(20);
    tracker = GAI.getSharedInstance().getTracker("UA-9999999-9");
}

@Override
public void sendView(String appScreen) {
    tracker.set(GAIFields.kGAIScreenName, appScreen);
    tracker.send(GAIDictionaryBuilder.createAppView().build());
}

@Override
public void sendEvent(String category, String action, String label,
        Long value) {
    tracker.send(GAIDictionaryBuilder.createEvent(category, action, label,
            NSNumber.valueOf(value)).build());
}

@Override
public void sendException(String description, boolean fatal) {
    tracker.send(GAIDictionaryBuilder.createException(description, fatal)
            .build());
}

@Override
public void sendSocial(String network, String action, String target) {
    tracker.send(GAIDictionaryBuilder.createSocial(network, action, target)
            .build());
}

@Override
public void sendTiming(String category, long intervalInMilliseconds,
        String name, String label) {
    tracker.send(GAIDictionaryBuilder.createTiming(category,
            NSNumber.valueOf(intervalInMilliseconds), name, label).build());
}

}

Hope you will fix it soon. Thank you very much.

[BlueRiverInteractive]

Thanks for your help! I've checked the old binding version and the current but couldn't find any real differences. I have now reverted GAITracker and GAIDefaultTracker. Can you please tell me if this changes anything?

[BlueRiverInteractive]

Ok I just found some difference. Seems like the creator of the initial version of the binding made GAITrackerImpl class and used it in several places in the GAI class. However, according to the obj-c header file, at these places the generic interface GAITracker should be used in these places. I just pushed another commit that removes the GAITrackerImpl (or GAIDefaultTracker as it is named now). I hope this fixes the issue finally.

[windlord0408]

After update newest code and replace GAIDefaultTracker with GAITracker in RobovmGoogleAnalytics, I got this error:

java.lang.IncompatibleClassChangeError: Class org.robovm.apple.foundation.NSObject does not implement the requested interface org.robovm.bindings.googleanalytics.GAITracker at com.test.RobovmGoogleAnalytics.sendEvent(RobovmGoogleAnalytics.java)

Please help me to fix it. Thanks.

[fechy]

I'm getting the same issue. I get:

Exception in thread "main" java.lang.IncompatibleClassChangeError: 
Class org.robovm.apple.foundation.NSObject does not implement the 
requested interface org.robovm.bindings.googleanalytics.GAITracker

My code looks like:

@Override
public boolean didFinishLaunching (UIApplication application, NSDictionary<NSString, ?> launchOptions) {
        boolean b = super.didFinishLaunching(application, launchOptions);

        // Configure Google Analytics
        GAI.getSharedInstance().setTrackUncaughtExceptions(true);
        GAI.getSharedInstance().setDryRun(false);
        GAI.getSharedInstance().setDispatchInterval(20.0);

        // Get Google Analytics
        tracker = GAI.getSharedInstance().getTracker(Settings.ANALYTICS_TRACK_ID);

        // Track page view
        this.sendView("Game");

        return b;
}

private void sendView(String appScreen) {
     tracker.set(GAIFields.kGAIScreenName, appScreen);
     tracker.send(GAIDictionaryBuilder.createAppView().build());
}

Any thoughts? Thanks!

[alessandro-lac]

Any news?

we are getting the same issue as windlord0408 and fechy. Tried to mess around with the library without any luck :(

[animvs]

I got the same error:

Exception in thread "main" java.lang.IncompatibleClassChangeError: Class org.robovm.apple.foundation.NSObject does not implement the requested interface org.robovm.bindings.googleanalytics.GAITracker

[jpancik]

java.lang.IncompatibleClassChangeError: Class org.robovm.apple.foundation.NSObject does not implement the requested interface org.robovm.bindings.googleanalytics.GAITracker

got same error. Any update?

Thanks

[animvs]

@jpancik, Sadly no. I've been messing around this issue without success.. I guess we need someone with more knowledge about robovm bindings..

[marcinjakubowski]

This has worked for me: https://gist.github.com/marcinjakubowski/fcf7e7f81925a51c3203 :

1. Create a new file GAITrackerImpl.java and copy the contents from the linked gist
2. Modify GAI.java according to my gist (basically change all occurrences of GAITracker to GAITrackerImpl)

I won't submit this as a pull request because I have no idea what I'm doing, it's probably not the right way it should be done, but I have never written a line of Objective-C in my life and it's my second day working with RoboVM. But it works and Google Analytics gets the data correctly, so I don't really care. Hope this helps someone.

[rotter]

I can confirm that @marcinjakubowski 's solution WORKS (thanks a lot!). And also I have no clue what he's done, as I have also never written a line of ObjC code and I'm very very new to RoboVM, started today playing with bindings.

Just to be clear, this is what I did:

GAI.getSharedInstance().setTrackUncaughtExceptions(true);
GAI.getSharedInstance().setDispatchInterval(20);

GAITrackerImpl tracker = GAI.getSharedInstance().getTracker("UA-key-stuff");

GAI.getSharedInstance().setDefaultTracker(tracker);

tracker.set(GAIFields.kGAIScreenName, "MyGameName");
tracker.send(GAIDictionaryBuilder.createAppView().build());

The GAITrackerImpl class is new, copied from @marcinjakubowski 's link. The GAI class was also copied from his link (replacing the original one).

[jpancik]

@marcinjakubowski @rotter Thank you! I also confirm it works. Already submitting new version to iTunes app store.. @BlueRiverInteractive could you look at this? Why it works?

[marcinjakubowski]

@jpancik I can explain a bit why it works: it's because Google has an implementation of the interface GAITracker which is private: the GAITrackerImpl. I read somewhere that one of RoboVM's limitations is support for such private implementations. I found out the name of the private class by reading toString of the returned GAITracker object (returned GAITrackerImpl@....), and then took the idea on how to make it work from Google Play Game Services implementation of GPPShareBuilder. But I think it's done better there, somehow the methods return the interface and not the private implementation and RoboVM recognizes the returned object correctly. I could not make it work so that GAI getTracker returns GAITracker and RoboVM recognizes it's GAITrackerImpl underneath, so I just made it dirty and had getTracker return GAITrackerImpl. I'm hoping someone who knows what they're doing can do it "the right way" :)

[WillCalderwood]

Does someone who's got this working want to push their fix? As no one else has suggested anything better in the last 6 months it's the best solution that we have.

[dungelin]

Below is code i used in my game, It work fine.

//Start Google Analytics
    GAI.getSharedInstance().setDispatchInterval(20);
    GAI.getSharedInstance().setTrackUncaughtExceptions(true);
    GAI.getSharedInstance().setDryRun(false);
    tracker = GAI.getSharedInstance().getTracker(gaID);
    //End Google Analytics      
           //send view
    tracker.send(GAIDictionaryBuilder.createEvent("Game Event", "Start Game", "Start Game",    NSNumber.valueOf(0)).build());
    // Track events with parameters.
    tracker.set(GAIFields.kGAIScreenName, "Game Screen");
           tracker.send(GAIDictionaryBuilder.createAppView().build())

[WillCalderwood]

Thanks @dungelin. I just did an exact copy/paste of your code and set my tracking id and I'm getting the error

java.lang.IncompatibleClassChangeError: Class org.robovm.apple.foundation.NSObject does not implement the requested interface org.robovm.bindings.googleanalytics.GAITracker

I guess there must be some issue with the way I'm importing the binding.

[marcinjakubowski]

@WillCalderwood have a look at the solution I posted here https://github.com/BlueRiverInteractive/robovm-ios-bindings/issues/48#issuecomment-48248092

[WillCalderwood]

@marcinjakubowski - if dungelin has got it working fine as is, then I might see if I can do the same first. I try to avoid hacking about with 3rd party libraries as then I just have a headache when they're updated which is why I suggested your solution should be pushed as the fix.

@marcinjakubowski & @dungelin What version of robovm are each of you using?

Thanks for the help

[marcinjakubowski]

I was on initially on 0.0.8 when my solution worked fine for me, updated to 0.0.10 and it was still working. I am now migrating to 1.0.0-alpha-04, but haven't finished yet so I'm not sure if it works correctly.

[dungelin]

@WillCalderwood i use latest robovm and Analytics here.

[dungelin]

@WillCalderwood I forgot, must include hack from @marcinjakubowski

[WillCalderwood]

Thanks, glad I didn't try without that. :-)

[wolfgangpue]

Does somebody have a link to the *.jar file of @marcinjakubowski fixed version? I use libgdx and don't want to compile the bindings by myself.

[marcinjakubowski]

You can just download the files and add them to your project directly, that's what I did. But maybe someone has a jar.
