Как использовать getChildFragment для googlemaps?

Question

Итак, у меня есть приложение с вкладками в студии android, где одна вкладка является картой во фрагменте. Как мне получить карту для запроса разрешения на отображение текущего местоположения с помощью getChildFragment? Iv пытался добавить getChildFragmentManager в моем onCreateView, но я не думаю, что это что-то делает.

Вот мой java

package com.example.vadtest.ui.main;

import android.Manifest;
import android.content.pm.PackageManager;
import android.location.Location;
import android.location.LocationManager;
import android.os.Build;

import android.view.View;
import android.view.ViewGroup;
import android.widget.TextView;

    }

    @Override
    public void onConnectionSuspended(int i) {

    }

    @Override

    }




}

Я застрял здесь. Я новичок в android студии, поэтому любая помощь будет оценена.
