Error:Attribute "theme" has already been defined

Question

I am using Android studio for building application. I am using this following dependencies:

1. play services : compile 'com.google.android.gms:play-services:5.2.08'
2. app combat v7 : compile 'com.android.support:appcompat-v7:21.0.0'
3. support Cardview : compile 'com.android.support:cardview-v7:21.0.0'
4. support Recycler view : compile 'com.android.support:recyclerview-v7:21.0.0'

I am getting following error while building my app:

Answer 1

just use latest (21)
appCompat and
google play services library

For example:

compile 'com.android.support:support-v4:21.0.0' compile 'com.android.support:appcompat-v7:21.0.0' compile 'com.android.support:recyclerview-v7:21.0.0'  compile 'com.android.support:cardview-v7:21.0.0' compile 'com.google.android.gms:play-services:6.1.11' 

then everything works :)
