java 获取 google地址

	private String getAddr(String latitude, String longitude){
		  String addr = ""; 

		// 也可以是http://maps.google.cn/maps/geo?output=csv&key=abcdef&q=%s,%s，不过解析出来的是英文地址
		// 密钥可以随便写一个key=abc
		// output=csv,也可以是xml或json，不过使用csv返回的数据最简洁方便解析
		String url = String.format(
				"http://ditu.google.cn/maps/geo?output=csv&key=abcdef&q=%s,%s",
				latitude, longitude);
		URL myURL = null;
		URLConnection httpsConn = null;
		try {
			myURL = new URL(url);
		} catch (MalformedURLException e) {
			e.printStackTrace();
			return null;
		}
		try {
			httpsConn = (URLConnection) myURL.openConnection();
			if (httpsConn != null) {
				InputStreamReader insr = new InputStreamReader(
						httpsConn.getInputStream(), "UTF-8");
				BufferedReader br = new BufferedReader(insr);
				String data = null;
				if ((data = br.readLine()) != null) {
//					System.out.println(data);
					String[] retList = data.split(",");
					if (retList.length > 2 && ("200".equals(retList[0]))) {
						addr = retList[2];
						addr = addr.replace("\"", "");
					} else {
						addr = "";
					}
				}
				insr.close();
			}
		} catch (IOException e) {
			e.printStackTrace();
			return null;
		}
		return addr;
