It works, after downloading installing updating three times in a row without luck, then i downloading, installling and WITHOUT updating, its now work normally without crash.
I dont know if after downloading should we update the SDK? or not?

 

[DonManfred]

should we update the SDK? or not?

Hi. I am getting the same error message

java.lang.IncompatibleClassChangeError: The method 'java.lang.Class java.lang.Object.getClass()' was expected to be of type interface but instead was found to be of type virtual (declaration of 'com.google.android.gms.dynamic.ObjectWrapper' appears in /data/app/b4a.identity-2/base.apk)

(refers to other libraries) on a tablet with Android version 7 when I use the latest Admob artifacts and try to load an ad with the LoadAD function. This seems to indicate that there is some kind of incompatibility. I only update the libraries indicated by the B4A SDK Manager.

I only update the libraries indicated by the B4A SDK Manager.

you should not update it i guess.

There is another identical thread about this recently and the solution was to reinstall the SDK and NOT updating anything.

Edit: it is this thread. See above

You should have created a new thread for your issue for sure.

 

[Rubsanpe]

Thank you Manfred. I was going to do it by creating a new thread, but coincidentally the error message is the same even though they are different libraries that are calling com.google.android.gms.dynamic.ObjectWrapper.

Only @Erel can say if the SDK has changed and if we should not do any updates.
In the past his answer was always not to update anything.
