android WIFI定位

WIFI定位其实和基站定位都差不多，只需要把WIFI的MAC地址取到传给google就行了，下面是具体实现！

[java]
import java.io.Serializable;

import android.content.Context;
import android.net.wifi.WifiManager;
import android.util.Log;

/**
* @author yangzhiqiang
*
*/
public class WiFiInfoManager implements Serializable {

    /**
     *
     */
    private static final long serialVersionUID = -4582739827003032383L;

    private Context context;

    public WiFiInfoManager(Context context) {
        super();
        this.context = context;
    }

    public WifiInfo getWifiInfo() {
        WifiManager manager = (WifiManager) context
                .getSystemService(Context.WIFI_SERVICE);
        WifiInfo info = new WifiInfo();
        info.mac = manager.getConnectionInfo().getBSSID();
        Log.i("TAG", "WIFI MAC is:" + info.mac);
        return info;
    }

    public class WifiInfo {

        public String mac;

        public WifiInfo() {
            super();
        }
    }

}
上面是取到WIFI的mac地址的方法，下面是把地址发送给google服务器,代码如下：

[java]
public static Location getWIFILocation(WifiInfo wifi) {
        if (wifi == null) {
            Log.i("TAG", "wifi is null.");
            return null;
        }
        DefaultHttpClient client = new DefaultHttpClient();
        HttpPost post = new HttpPost("http://www.google.com/loc/json");
        JSONObject holder = new JSONObject();
        try {
            holder.put("version", "1.1.0");
            holder.put("host", "maps.google.com");

            JSONObject data;
            JSONArray array = new JSONArray();
            if (wifi.mac != null && wifi.mac.trim().length() > 0) {
                data = new JSONObject();
                data.put("mac_address", wifi.mac);
                data.put("signal_strength", 8);
                data.put("age", 0);
                array.put(data);
            }
            holder.put("wifi_towers", array);
            Log.i("TAG", "request json:" + holder.toString());
            StringEntity se = new StringEntity(holder.toString());
            post.setEntity(se);
            HttpResponse resp = client.execute(post);
            int state = resp.getStatusLine().getStatusCode();
            if (state == HttpStatus.SC_OK) {
                HttpEntity entity = resp.getEntity();
                if (entity != null) {
                    BufferedReader br = new BufferedReader(
                            new InputStreamReader(entity.getContent()));
                    StringBuffer sb = new StringBuffer();
                    String resute = "";
                    while ((resute = br.readLine()) != null) {
                        sb.append(resute);
                    }
                    br.close();

                    Log.i("TAG", "response json:" + sb.toString());
                    data = new JSONObject(sb.toString());
                    data = (JSONObject) data.get("location");

                    Location loc = new Location(
                            android.location.LocationManager.NETWORK_PROVIDER);
           &nbs
