google places APIを使用して現在地を取得する

Question

私は現在の場所を取得するためにgoogle places APIを使用しようとしていますが、何も表示されていません。電話でこれを実行しています。このコードに関しては、forループexecuted.Iがここ

<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/> 
    <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/> 
    <uses-permission android:name="com.google.android.providers.gsf.permission.READ_GSERVICES"/> 
    <uses-permission android:name="android.permission.INTERNET"/> 
    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" /> 

のように、マニフェストファイル内のすべての必要な許可を与えているということは私のコードでされていない

Answer 1

あなたはmGoogleApiClientが時に接続されてください。このコードを実行していますか？そうは思わない。 onConnected（）メソッドでPendingResult関数を使用してみませんか？この呼び出しは非同期なので、このコードを実行するときにはまったく接続されていない可能性があります。 onConnected（）のトーストは表示されていますか？
