Compile error when use admob+google play service Extension

I had success to compile android with Admob extension based on this guide (https://github.com/bradparks/HaxeFlixel_extensions3) . But when i merge admob and google play service, compile failed with error message “Jar mismatch! Fix your dependencies”.

I’m guessing more than one version of Google Play Services is being included.

Due to the license terms of Google Play Services, it should not be distributed, so it shouldn’t be included in those extensions. Instead, it should be possible to install the library using the Android SDK Manager nowadays, and then to use something like this:

Perhaps it would be possible for other extensions to modified to do something like this as well (or to use this exact project)
