Rendering Problems: Android Studio - android-studio

Question

I have just downloaded Android Studio, and when I try and create an Android Wear project it says:
Exception raised during rendering: android.support.wearable.view.WatchViewStub.requestApplyInsets()".
I've got no idea what this means or how I go about fixing it. My only guess was maybe SDK? This is what I've got:
android {
compileSdkVersion 20
buildToolsVersion "20.0.0"
defaultConfig {
applicationId "com.example.helloworld.myapplication"
minSdkVersion 20
targetSdkVersion 20
versionCode 1
versionName "1.0"
}
buildTypes {
release {
runProguard false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
}
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
compile 'com.google.android.support:wearable:+'
compile 'com.google.android.gms:play-services-wearable:+'
}
And this is the error:
If anyone has any ideas I'd be most grateful!
Thanks
