I've created a demo wear project with android studio without touching anything. In build.Gradle this error occurs, although I find curious that it lets the app compile.
Project depends on com.google.android.support:wearable:2.0.2, so it must also depend (as a provided dependency) on com.google.android.wearable:wearable:2.0.2
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
compile 'com.google.android.support:wearable:1.4.0'
compile 'com.google.android.gms:play-services-wearable:9.4.0'
}
