所以我有一個谷歌地圖應用程序在android工作室，我想設置它。我看着樹屋他們如何設置它與谷歌自己的位置提供商和一切必要http://blog.teamtreehouse.com/beginners-guide-location-androidAndroid Studio模擬器崩潰LocationServices.fusedLocationApi
我已經做了一切它說，它在我的手機上工作正常，但模擬器崩潰在啓動時，它說故障是在該行
LocationServices.FusedLocationApi.requestLocationUpdates(this.mGoogleApiClient, this.mLocationRequest, this);
我不知道我該怎麼辦。我甚至使用控制檯來geo修復模擬器中gps的位置，但沒有任何結果。這是我的完整代碼
