我完全新的android.I想實現一個可拖動的谷歌地圖就像超級app.I從什麼地方找到了一個代碼，但是當我嘗試運行的幾個問題進行了未來像實現谷歌地圖一樣尤伯杯
Error:(24, 37) error: cannot find symbol class GooglePlayServicesClient Error:(26, 39) error: cannot find symbol class LocationClient
在我依賴我已經加入
compile 'com.google.android.gms:play-services:8.4.0'
以下是我所使用的代碼。

我的要求是類似這樣的東西
。 請幫我解決這個問題。任何幫助，將不勝感激。提前
我想你需要使用最新的谷歌播放庫。該錯誤表明，不能找到LocationClient類。更新您的googleplay並檢查它是否仍然存在相同問題。謝謝。 – RAAAAM
我已經更新了我的googleplay，但仍然沒有運氣.. :( –
