Google Play Services を使用して現在の場所を見つけています。しかし、それはどのコールバック関数にも入っていません。Google API クライアントに接続できません。
LocationUtilクラスの私のコードは次のとおりです。
package com.steporganization.util;
import android.app.Activity;
import android.content.Context;
import android.location.Location;

import com.google.android.gms.location.LocationListener;
import com.google.android.gms.location.LocationRequest;
import com.google.android.gms.location.LocationServices;

別のアクティビティでは、このクラスのオブジェクトを作成してgetUserCurrentLocation(this,getApplicationContext())関数を呼び出しています。
ここで私が間違っていることを誰かに教えてもらえますか? また、それは正しいコードではありませんが、要件に応じてロジックを変更できるように、コールバック関数内に到達しない理由が私のポイントです。
また、同様の質問を見つけましたが、まだ回答がありません。
