I installed it to a parallel path to the SDK directory, called OLDSDK as google warns that you should not alter the contents of this directory.
So in my code it is:
B4X:
'Not working with Play Services - V30
'#AdditionalRes: $AndroidSDK$\extras\google\google_play_services\libproject\google-play-services_lib\res, com.google.android.gms
' Installed V29 in oldSdk
#AdditionalRes: $AndroidSDK$\..\oldsdk\extras\google\google-play-services\libproject\google-play-services_lib\res, com.google.android.gms
This works fine.
Will V6.0 of B4A support the new Google Play Services structure?
