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！

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：

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);
					loc.setLatitude((Double) data.get("latitude"));
					loc.setLongitude((Double) data.get("longitude"));
					loc.setAccuracy(Float.parseFloat(data.get("accuracy")
							.toString()));
					loc.setTime(System.currentTimeMillis());
					return loc;
				} else {
					return null;
				}
			} else {
				Log.v("TAG", state + "");
				return null;
			}

		} catch (Exception e) {
			Log.e("TAG", e.getMessage());
			return null;
		}
	}
