Android Question Material Design and Google Play Services theme attribute conflict

[Ohanian]

Hi,

I’m working on a project that uses google map, I’ve decided to start using material design on this project, but it seems that there’s some conflict between some attributes.

Here’s the code of the project (just an empty project with these attributes) and the error message:

#AdditionalRes: ..\resource
#AdditionalRes: C:\Users\USER\AppData\Local\Android\android-sdk\extras\android\b4a_appcompat, de.amberhome.objects.appcompat
#AdditionalRes: C:\Users\USER\AppData\Local\Android\android-sdk\extras\android\support\v7\appcompat\res, android.support.v7.appcompat
#Extends: android.support.v7.app.ActionBarActivity


#AdditionalRes: C:\Users\USER\AppData\Local\Android\android-sdk\extras\google\google_play_services\libproject\google-play-services_lib\res, com.google.android.gms

error message :

C:\Users\USER\AppData\Local\Android\android-sdk\extras\android\support\v7\appcompat\res\values\attrs.xml:505: error: Attribute "theme" has already been defined

Any suggestion?
