android - GUIStatics を変数に解決できません

Question

次のコードからユーザーの場所の名前を取得しようとしています。GUIStatics を変数に解決できないため、エラーが発生します。それを修正する方法。また、このコードが場所の名前を取得するための正しい方法であるかどうかを誰でも知ることができます。

package com.example.location;

import java.util.List;
import java.util.Locale;

import android.location.Address;
import android.location.Criteria;

private double latitude,longitude;


@Override
protected void onCreate(Bundle savedInstanceState) {
    mContext=this;
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    t=(TextView)findViewById(R.id.textView1);

    lmanager=(LocationManager)getSystemService(Context.LOCATION_SERVICE);
    lmanager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 0, 0, this);
    lmanager.requestLocationUpdates(LocationManager.NETWORK_PROVIDER, 0, 0, this);

    locationUpdate();


}

    }
    catch(Exception e)
