More GDPR pain cometh for apps serving Ads...

MobAmuse · June 2023

'Later this year, Google will require all publishers serving ads to EEA and UK users to use a Google-certified Consent Management Platform (CMP). You can use any Google-certified CMP for this purpose, including Google's own consent management solution. If you are interested in using Google's consent management solution, start by setting up your GDPR message and implementing the UMP SDK.'

https://support.google.com/admob/answer/10113005

Just sayin.

and how can we implement this ump sdk?
is it possible in gideros?
It seems that they are already starting to ask for it

hgy29 · July 2023

Since it seems to be linked with AdMob currently, I would add it as an extension to AdMob plugin to start with, although getting consent from the user is more general than just for ads. We'll need to define new APIs at lua side.
Maybe something like ads:checkConsent(consentRequirements)' which would trigger a consent result event giving the outcome of the consent request.

It would be great if it solves the admob problem.
thank you so much.
please notify us when available...

I added an ads:checkConsent({ reset=false, underAge=false }) call for AdMob. It has to be called at every app launch. 'reset' is here for debug, and 'underAge' has to be set according to the user's age.
If the call returns true, it means consent flow is supported, and a 'AD_CONSENT' event will be triggered giving the outcome. The event has an 'error' field (textual error) and an 'errorcode' field, which is 0 if successful.

rodri · August 2023

thank you so much

we're going to try it

rodri · August 2023

excuse me
I'm a bit new to gideros...

checkConsent fixes or implements the UMP SDK?

I tried to add in an app, but I get this error:

config.lua.gideros_merged:593: attempt to call method 'checkConsent' (a nil value)

I have an object

if application:getDeviceInfo() == "Android" then
require "ads" --create real object for on device

ADMOB = Ads.new('admob')
and the call

ADMOB:checkConsent(false, false)

it gives me the error:

config.lua.gideros_merged:593: attempt to call method 'checkConsent' (a nil value)

try anyway
ADMOB:checkConsent({ reset=false, underAge=false })

or
local cons
cons=ADMOB:checkConsent(false, false)

Do you have an example of how to implement it please? @hgy29 @MoKaLux

Sorry I haven't tried Ads for a while, but I think this is how it should be setup:
ADMOB:checkConsent({ reset=false, underAge=false })
May be you need to add this code in Event.AD_CONSENT? Something like:

ADMOB:addEventListener(Event.AD_CONSENT, function(e)
	ADMOB:checkConsent({ reset=false, underAge=false })
	...
end)

hgy29 · August 2023

Hi @rodri, your code should work. Are you using Gideros 2023.8 ?

rodri · August 2023

yes
I just installed..

hgy29 · August 2023

And you rebuilt your android player with it, right ?

rodri · August 2023

sorry

I do not know how to do it...

now install the apk GiderosAndroidPlayer.apk

from the directory: gideros/players

and now I get this error:

[string "luabinding/compatibility.lua"]:79: Module ads not found

MoKaLux · August 2023

the GiderosAndroidPlayer.apk that comes with Gideros doesn't have the Ads plugin built-in, you need to build GiderosAndroidPlayer.apk yourself but don't worry it is easy

export your project
in the android tab you can change the package name
uncheck build android bundle
check build apk file
then below instead of full export, select Player (no assets)
then install it on your phone

I have it on my GH but it doesn't have the Ads plugin (couldn't make it work at the time

), I will try again with the Ads plugin later

https://github.com/mokalux/gideros-player-for-android

rodri please let me know if that doesn't help

rodri · August 2023

hello..
thank you...

I was able to create the player..

I already put a "gdpr message" in the ADMOB account

There were 3 screen formats with consent questions. and it asked me to associate it with an application...

I already did. I am testing on my pc, no consent screen or something similar appears here. Maybe when I publish the application in the playstore... or I'm not doing something right...

I still don't know very well what the event is for... what I put is very simple, just this:

CODE:

--**************************************************
-- *********** para GDPR *******************
--**************************************************

ADMOB_GDPR_READY=false

if application:getDeviceInfo() == "Android" then
require "ads" --create real object for on device

ADMOB_GDPR = Ads.new("admob")

local con=false

con=ADMOB_GDPR:checkConsent({ reset=false, underAge=false })
print ("consent",con)

ADMOB_GDPR:addEventListener(Event.AD_CONSENT, function(e)
--

ADMOB_GDPR_READY=true
print("event ok")
end)

The application works fine, but it doesn't show any consent form, maybe I'm missing something...
thanks for your cooperation.

hgy29 · August 2023

Hi @rodri,

The event tells event the outcome of the consent request:

		ads:addEventListener(Event.AD_CONSENT, function(e)
			print("AdConsent",e.error,e.errorcode)
		end)

It is only fired if 'checkConsent' returnned true in first place (meaning consent flow was actually started). The error string may help you figuring out whats wrong.

I tested with GPS version 21.5.0 without an actual admob account (I used test account).

rodri · August 2023

everything is alright

I already tried it and it works perfectly, it activates the ADMOB consent forms...

Prerequisites:
You must have a GDPR message from admob configured and linked to your application...
you can link a message to several applications...

I did it using gideros 2023.8
and GPS 22.3.0
and android target version 33

thanks for the support and regards.

MobAmuse · October 2023

Sorry late to my own party

but I just tried all this and no go...

I'm using latest Gideros 2023.10 with GPS 22.3.0 and target version 33 exporting and a test .apk sent to Google Pixel 8 Pro. I have published the GDPR message correctly in my AdMob account too for several apps.

Note: I'm also using latest Android Studio Giraffe with all updates applied.

--- Code ---

require "ads"
admob=Ads.new("admob")
admob:setKey("...removed...")
admob:checkConsent({ reset=false, underAge=false })

admob:addEventListener(Event.AD_CONSENT, function(e)
print("AdConsent",e.error,e.errorcode)
end)

--- Logcat ---

Logcat gives me this on booting the app on the device...

Without...

admob:checkConsent({ reset=false, underAge=false })

...the code runs normally but I see no consent message of course.

hgy29 · October 2023

@MobAmuse, I reviewed the code and the only reason that would lead to that crash is that the call to 'checkConsent' is issued before AdMob is compltely initialized. It turns out that the last part of intiialization started in Ads.new() is run asynchronously on UI Thread, so initialization may not be complete yet by the time you call checkConsent().

I suggest you skip one frame before calling checkConsent() (or other calls such as showing an ad).

MobAmuse · October 2023

Great suggestion, that worked

Thank you.
