hereの例を使用してAndroid Wear 2.0デバイスの場所を取得しようとしています。私がインポートされている：Android Wear：MainActivityはcom.google.android.gms.location.LocationListenerにキャストできません
com.google.android.gms.location.LocationListener
com.google.android.gms.location.LocationRequest
com.google.android.gms.location.LocationServices
しかし、私はエラーが発生します：

私は本当に私がcom.google.android.gms.location.LocationServicesをインポートするよ、私はandroid.location.LocationServicesをインポートしていないよ、何をするか分からないので、それはdoesnのGoogleのグーグルが2つのライブラリを切り替えるように指示しているので、なぜこのエラーが表示されるのかはわかりません。あなたがラインthisがあなたのMainActivityある
