在应用开发中我们常常需要网络获取位置的方法，这里做一个工具类的封装，使用的是Android原生定位，包含两种方式，一种是原生GPS一种是网络定位的封装实现：

工具类代码如下所示：

package com.vondear.tools.tools;

import android.Manifest;

import android.content.BroadcastReceiver;

import android.content.Context;

import android.content.Intent;

import android.content.IntentFilter;

import android.content.SharedPreferences;

import android.content.pm.PackageManager;

import android.location.Location;

import android.location.LocationListener;

import android.location.LocationManager;

import android.net.ConnectivityManager;

import android.net.NetworkInfo;

import android.os.Bundle;

import android.support.v4.app.ActivityCompat;

import android.app.Activity;

import android.support.v4.content.LocalBroadcastManager;

import android.view.accessibility.AccessibilityManager;

import android.widget.Toast;

import com.ta.utdid2.android.utils.SharedPreferenceHelper;

import java.io.BufferedReader;

import java.io.BufferedWriter;

import java.io.FileInputStream;

import java.io.FileOutputStream;

import java.io.IOException;

import java.io.InputStreamReader;

import java.io.OutputStreamWriter;
