Google Play warning: Your app is using an incorrect implementation of in-app billing

Hello :slight_smile:

I’ve just received (to day) an email from Google Play who’s saying that my app is invoking the in-app billing service without setting a target package for the intent…?, this version of the app was an only BluePrint successfully builded with UE4.11 and published on Google Play since 05/16/2016…

I will investigate for that question but if someone know how to fix it, it will be very welcome :wink:

Thanks for your help

Best Regards

  4. Check back after five hours - we’ll show a warning message if the app hasn’t been updated correctly. We’re here to help

Same situation here.

Look like seriues matter, moving this to bug raport should have better reponce not to mention it’s something that needs to be fixed. Hmm do the same thing happends in 4.12?

I received same letter from Google play.
I used engine version 4.12.3. How can I resolve this issue?

Same here. I used 4.12 . Waiting for answer.

me too! 4.12.3

Same situation here.

Ok so i change version used to as there 4.12 raports

Same here, any planning on fix Epic? is up to date in 4.12 and we do the setPackage call already.

The likely issue is the version of Google Player Services. We included rev19 which is version 5.0.89. For 4.13 I have updated this to 9.2.0 by adding support for AAR files from the package repositories.

For 4.12 if you are working with source you can try integrating this GitHub commit: link text

Since GitHub doesn’t have binaries you’ll need to skip the gpg-cpp-sdk.v2.1 and OnlineExternalUIInterfaceGooglePlay.cpp updates unless you download the library (.a) files from Google and place them in Engine/Source/ThirdParty/GooglePlay/gpg-cpp-sdk.v2.1/gpg-cpp-sdk/android/lib/c++ yourself.

Make sure you delete these (they will come from the repository now):



Run the Android SDK Manager installer and under Extras, make sure you have installed Android Support Repository rev35 and Google Repository rev31.

Thx for your answer, I recently build the github release branch of UE4 (4.12.5); but I think better switch to the 4.13 Branch to stay up to date, I will keep you updated…
Thanks again

me too (on 4.12.5 version) !!! any planning on fix Epic?
