元の答え

これは、FusedLocationProviderApiが最近のバージョンのGoogle Playサービスでは非推奨になったためです。こちらで確認できます。公式ガイドでは、 FusedLocationProviderClient の使用を提案しています。詳細なガイド はこちら にあります。

例えばonCreate()の内側にFusedLocationProviderClientインスタンスを作成する

 mFusedLocationClient = LocationServices.getFusedLocationProviderClient(this);

そして、あなたがしなければならないのは、電話をかけることだけです

mFusedLocationClient.getLastLocation()
    .addOnSuccessListener(this, new OnSuccessListener<Location>() {
        @Override
        public void onSuccess(Location location) {
            // Got last known location. In some rare situations, this can be null.
            if (location != null) {
                // Logic to handle location object
            }
        }
    });

単純じゃないですか?


重要なアップデート(2017年10月24日):

昨日、Googleは公式開発者ページを という警告 で更新しました。

FusedLocationProviderApiクラスを引き続き使用し、Google Playサービスバージョン12.0.0が入手可能になるまでFusedLocationProviderClientクラスに移行しないでください。これは2018年初頭に出荷される予定です。バージョン12.0.0より前のFusedLocationProviderClientを使用するとGoogle Playサービスが端末上で更新されます。ご不便をおかけして申し訳ありません。

warning だからGoogleが問題を解決するまで私たちは廃止予定のLocationServices.FusedLocationApiを使い続けるべきだと思う。


最新のアップデート(2017年11月21日):

警告は表示されなくなりました。Google Playサービス11.6 2017年11月6日、リリースノート のコメント: Fixed FusedLocationProviderClient issue that occasionally caused crashes when Google Play services updated. Play Servicesは、バックグラウンドで自動的に更新されてもクラッシュしません。それで、私たちは今新しいFusedLocationProviderClientを使うことができます。

この方法を使う

mFusedLocationClient.requestLocationUpdates(mLocationRequest, mLocationCallback, Looper.myLooper());

はい、廃止予定です。
以下はnew FusedLocationProviderClient を使用する際に必要となるポイントです。

  1. import com.google.Android.gms.location.FusedLocationProviderClient; ????としてインポートする
  2. 私はあなたが LocationListener インターフェースを実装していることに気づきます。 mFusedLocationClient.requestLocationUpdates()メソッドでは、LocationListenerをパラメータとして取りません。あなたは LocationCallback を提供することができます。これは抽象クラスなので、LocationListenerのように実装することはできません。 Googleの ガイド で述べられているように、コールバックメソッドを作り、 'this'の代わりにそれを渡してください。 import com.google.Android.gms.location.LocationCallback;としてインポート
  3. LocationCallbackでは、 onLocationChanged() の代わりに onLocationResult() を使用できます。 Locationオブジェクトではなく LocationResult オブジェクトを返します。この結果オブジェクトで利用可能な最新の位置を取得するには、LocationResult.getLastLocation()を使用します。 import com.google.Android.gms.location.LocationResult;としてインポート
