Are you setting your linker to full?

[Big-ED]

Can you tell more? I will check, inapp billing implemented by another developer, so I not fully understand yet how it's work

Thanks, I found what I have "SDK assemblies only", I will try to change to "SDK and User assemblies"

or I should set - none?

Also I have proguard turned on.

[EmilAlipiev]

it is other way around "SDK assemblies only" shouldnt give any problem.

[jamesmontemagno]

I recommend only "SDK assemblies only"

[Toine-db]

I have the same issue with "SDK assemblies only"

[jamesmontemagno]

Most likely has to do with the billing library itself.

Will eventually upgrade to: https://android-developers.googleblog.com/2017/09/google-play-billing-library-10-released.html

in the latest version i now ask on Connect what type of purchase you are tryign to make.

If i get an exception then i return false on connect as things are supported on that device.
