Google Analytics: Tracker not started

jeudyx · November 30, 2016, 11:11pm

Hey @reedrichards, I found the problem, but its really really weird.

There is an uncaught exception in the Java code for the plugin in the UniversalAnalyticsPlugin.java file, in the execute function:

public boolean execute(String action, JSONArray args, CallbackContext callbackContext) throws JSONException {
    if (START_TRACKER.equals(action)) {
        String id = args.getString(0);
        this.startTracker(id, callbackContext);
        return true;
    } else if (TRACK_VIEW.equals(action)) {
        int length = args.length();
        String screen = args.getString(0);
        System.out.println("GoogleAnalytics JEUDY dentro de execute para llamar a trackView con screen: " + screen);
        try{
          this.trackView(screen, length > 1 ? args.getString(1) : "", length > 2 ? args.getBoolean(2) : false, callbackContext);
        }catch(Exception ex){
          System.out.println("GoogleAnalytics OOPS something wrong on execute: " + ex.getMessage());
          this.trackView(screen, "", false, callbackContext);
        }

This showed up in my logs:

11-30 17:08:14.917 7119 7164 I System.out: GoogleAnalytics OOPS something wrong on execute: Value null at 2 of type org.json.JSONObject$1 cannot be converted to boolean

So just to test I went ahead and called trackView with the default params and voilá ! got activity in GoogleAnalytics.

So the problem is that trackView was never being called in the java code of the plugin. No idea how it works for others or why it fails on my installation.

Congrats!!! Was a pretty good idea to add traces to the plugin itself, well done.

May I ask, where do you mean with “I went ahead and called trackView with the default params”?

Graphefruit · December 1, 2016, 1:45pm

Did you already report this issue?
I tried to change this on my side aswell but tracker still not starting

jeudyx · December 1, 2016, 2:36pm

In the catch, I call it

this.trackView(screen, “”, false, callbackContext);

but that was just for testing.

jeudyx · December 1, 2016, 2:37pm

Hi @Saalbach

This issue in the java part is for the trackView, when the tracker is already started.

What fixed the “tracker not started” for me was to implement everything in a service, and make sure you include the cordova.js file in your index.html before including the other js files.

reedrichards · December 1, 2016, 2:50pm

Thx for the documentation. Maybe would it be good to open a ticket in the project’s GitHub.

And again, congrats for finding the solution, have fun now

Graphefruit · December 1, 2016, 2:57pm

Hi @jeudyx

I’ve changed it within the Java-Part but had no effect for me, but I’ve already seen that you commited an Bug on Github! Maybe the fixed PR will help me.

Thanks so far

nhatnxbk · December 2, 2016, 10:50am

I had the same problem too . Any one please help

If you are using plugin version 1.7 that it has a bug, it won’t work on Android… I had same issue so I downgrade to 1.6.0 and it’s start working again…

you can also track bug on https://github.com/danwilson/google-analytics-plugin/issues/291

platform.ready().then(() => {
GoogleAnalytics.startTrackerWithId(YOUR-ANALYTICS-ID);      GoogleAnalytics.setAllowIDFACollection(true);
});

GoogleAnalytics.trackView('Track what you want to.');

Glad I found this thread. It’s a bit of a consolation to see that I’m not the only one having bad luck with this!

For those who got it to work on Android, how did you make sure it’s 1.6.0? Is it that it shows the version on “ionic plugins”? Did you also have to update config.xml and package.json with the 1.6.0 version?

I started looking at alternatives to Google Analytics for this, but couldn’t really come up with anything. Ionic’s version of Analytics (https://docs.ionic.io/services/analytics/) is not yet available.

reedrichards · December 5, 2016, 8:09am

Maybe try removing the plugin:

cordova plugin remove cordova-plugin-google-analytics --save

And then adding the specific version:

cordova plugin add cordova-plugin-google-analytics@1.6.0 --save

jigsaxis · December 5, 2016, 9:10am

Yes you can do as reedrichards told, you can check your plugin version under plugin/google-analytics-plugin/plugin.xml file

xke · December 6, 2016, 6:33pm

@reedrichards and @jigsaxis, thank you for the tips!

looks like my Google Analytics tracking is now working, using the 1.6.0 version. Woohoo!

baadier1 · December 7, 2016, 9:49am

@reedrichards and @jigsaxis.

I downgraded to 1.6.0 and still not able to build Google Analytics.

I get the following error:

* What went wrong:
Execution failed for task ':processDebugGoogleServices'.
> Please fix the version conflict either by updating the version of the google-services plugin (information about the latest version is available at https://bintray.com/android/android-tools/com.google.gms.google-services/) or updating the version of com.google.android.gms to 9.2.0.

Nothing that I’ve found in Google works.

Any ideas?

reedrichards · December 7, 2016, 10:37am

No idea. Maybe a targetSdkVersion problem or maybe your local android sdk should be updated?

analista.carlosh · December 29, 2016, 1:20pm

Thank’s, for me resolved.

Try to use Google Analytics Native Plugin for Ionic 3 Applications check tutorial here http://www.freakyjolly.com/add-google-analytics-in-ionic-3-application-using-cordova-and-ionic-native-plugin/

czumelzu · July 23, 2019, 5:08pm

Is a problem related with google-play-services incompatibilities. For fix it you have to make sure that all the PLAY_SERVICES_VERSION are the same, in my case for google-maps, googleplus and the rest I used 15.0.2, but for analytics I have to use 15.0.2 (because there are not a 15.0.1 in maven repo).

SO go to your config.xml and add/change your analytics plugin tag to

    <plugin name="cordova-plugin-google-analytics">
        <variable name="PLAY_SERVICES_VERSION" value="15.0.2" />
    </plugin>

and make sure that all the other plugins have some 15.* version. (if you are using another one just make sure that all play service use the same version)

Then if you already added a platform, go to platforms/android/project.properties and the same, just make sure that all play-services libraries are the same version. for example I have:

cordova.system.library.10=com.google.android.gms:play-services-analytics:15.0.2
cordova.system.library.13=com.google.android.gms:play-services-maps:15.0.1

…

Hope that this work for you, work for me after a lot of research.

czumelzu · January 15, 2020, 9:20am

UPDATE: With new changes of the library now works properly with 15.0.1 version of play services. They fixed the google play version on last versions of the package
