B4A Library Google Analytics v4 library

Erel · Jan 8, 2013

Google Analytics V4: https://developers.google.com/analytics/devguides/collection/android/v4/

The instructions were updated to reflect V4 changes. Note that this library will only work with B4A v3.82+.

Setup instructions:
- Download Google Play Services from Android SDK Manager and copy google-play-services.jar to the additional libraries folder.
- Create a Mobile App Analytics account: https://support.google.com/analytics/answer/1042508

The tracker is configured with an XML file. You should create a file with the following text named analytics.xml and put it under Objects\res\xml (create this folder if needed):

<?xml version="1.0" encoding="utf-8" ?>

<resources>

<string name="ga_trackingId">UA-xxxxx-y</string>


<bool name="ga_autoActivityTracking">true</bool>


<bool name="ga_reportUncaughtExceptions">true</bool>

</resources>

Make sure to set this file to be read-only. Otherwise the IDE will delete it during compilation.

You should declare a single AnalyticsTracker in Sub Process_Globals of your main module (or other module). The single tracker should be used from all modules.

B4X:

Sub Process_Globals
   Public tracker As AnalyticsTracker
End Sub

Sub Globals

End Sub

Sub Activity_Create(FirstTime As Boolean)
   If FirstTime Then
     tracker.Initialize
   End If
   tracker.SendScreenView("Main Activity")
End Sub

Other implemented methods: TrackEvent, SendTransaction, SendTiming and SendProduct. Note that you can pass empty strings for optional parameters.

Great thanks!

Great work, thanks a lot!
Unfortunately Google released beta 4 just yesterday, which changes some of the interfaces.
If I'm not mistaken, the new beta doesn't work with the library due to that.
Beta 3 isn't available on Googles servers anymore.
Could you maybe Upload beta 3 of Google's library here?

Nevermind, found a webpage hosting the library.
In case anyone needs it, it is available here:

You can use the latest version from Google. It should work fine.

JonPM · Jan 15, 2013

Even when I set analytics.xml to read only the IDE appears to delete the file and folder ("values"). Any ideas?

Erel · Jan 15, 2013

How are you setting the read-only flag?

You can also use this custom build action:

B4X:

#CustomBuildAction: 1, c:\windows\system32\attrib.exe, +r res\*.* /s

JonPM · Jan 15, 2013

In windows explorer, file properties.

Erel · Jan 16, 2013

values folder should be under res folder.

JonPM · Jan 16, 2013

I can't get this to work. Have you successfully tested this in 2.5?

Steps I'm using:
Create analytics.xml, save to desktop, set read only in file properties.
Create folder: myapp/Main/Objects/res/values/
Copy analytics.xml to values folder, confirm it is set to read-only

On compile I can see the folder 'values' being deleted still. I have tried using the CustomBuildAction code in my Main activity.
I've opened the APK and can confirm analytics.xml is not in there.

Yes.

The folder should be: myapp/Objects/res/values/

JonPM · Jan 17, 2013

Ok I found the problem. I keep all of my projects on an external wifi hard drive, when I copied to project locally and compiled it did not delete the read-only file. Seems to only do it when I compile over the network.

How can I use "Manual Screen Measurement"?
https://developers.google.com/analytics/devguides/collection/android/v2/screens

Erel · Jan 21, 2013

You should follow the instructions for automatic screen tracking. The name of each activity is: <package name>.<activity (lower cased)>

Hi Erel,
I want to use sendView as PageView that old Analitcs library method.
I used Pageview at my apps. But in new library, I can not find a right method for it.

Erel · Jan 21, 2013

The new Google library works differently. You will need to use the old library if you want to imitate page views.

QLogic · Jan 30, 2013

where is the associated libGoogleAnalyticsV2.xml file at by the way?

Erel · Jan 31, 2013

There isn't such a file. It is not needed.

QLogic · Jan 31, 2013

Noted.

But I get an error when trying to use the TrackEvent method.

B4X:

** Activity (main) Create, isFirst = true **


** Activity (main) Resume **


startService: class qlgc.pkg.pushservice


** Service (pushservice) Create **
** Service (pushservice) Start **
** Activity (main) Pause, UserClosed = true **


** Activity (portal) Create, isFirst = true **


** Activity (portal) Resume **


portal_imghpcross_click (java line: 485)

Here is the code snippet:

B4X:

Sub imgHPCross_Click
   tracker.TrackEvent("c1", "a1", "l1", 100)
   tracker.Dispatch
   Activity.RemoveAllViews
   Activity.Finish
   StartActivity("HPPortal")   
End Sub

Have you called Tracker.Start?
