最近做一個車載裝置app，裝置獲取北斗gps資料上傳的到後臺，app通過後臺提供的經緯度反取地理編碼位置，支援Google和百度。

獲取地理位置url

//Google
public String getGoogleUrl(boolean isCn, String longitude,String latitude) {
    if (!isCn) {
        return "http://maps.google.com/maps/api/geocode/json?latlng="+latitude+","+longitude+"&sensor=false&language="
 

                + Locale.getDefault().getLanguage() + "-" + Locale.getDefault().getCountry();
    } else {
        return "http://ditu.google.cn/maps/api/geocode/json?latlng="+latitude+","+longitude+"&sensor=false&language="
                + Locale.getDefault().getLanguage() + "-" + Locale.getDefault().
 
getCountry();
    }
}

//百度，到百度地圖獲取ak金鑰
public String getBaiduUrl(String longitude,String latitude) {
    return "http://api.map.baidu.com/geocoder/v2/?" +
            "ak=ahH7ICSO020gfifmGVog5OTimwq" +
            "&mcode=DC:B1:26:FF:66:49:62:85:98:16:AE:2A:E8:69:A9:EE:AC:14:3B;com.icar.taxi" +
            "&output=json"
 
 +
            "&pois=0&location="+latitude+","+longitude;
}

獲取詳細街道地址

/**
* @return 詳細街道地址
*/
public String getAddress(String url){
    //定義一個HttpClient，用於向指定地址傳送請求
    HttpClient client = new DefaultHttpClient();

    //向指定地址傳送Get請求
    HttpGet hhtpGet = new HttpGet(url);
    StringBuilder sb = new StringBuilder();
    try {
        //獲取伺服器響應
        HttpResponse response = client.execute(hhtpGet);
        HttpEntity entity = response.getEntity();

        if(entity !=null){   
            BufferedReader reader = new BufferedReader(new InputStreamReader(entity.getContent(),"UTF-8"),8192);   
            String line =null;   
            while ((line= reader.readLine())!=null){   
                sb.append(line +"\n");   
            }   
            reader.close();   
        }   

        //將伺服器返回的字串轉換為JSONObject  物件
        JSONObject jsonObject = new JSONObject(sb.toString());
        //從JSONObject 中取出location 屬性
        if (AppConfig.mapType()) {
            return jsonObject.optJSONObject("result").optString("formatted_address");
        } else {
            return jsonObject.optJSONArray("results").optJSONObject(0).optString("formatted_address");
        }
    } catch (ClientProtocolException e) {
        e.printStackTrace();
    } catch (IOException e) {
        e.printStackTrace();
    } catch (JSONException e) { 
        e.printStackTrace();
    } catch (Exception e) {
        e.printStackTrace();
    }
    return null;
}
