基站定位原理：通过手机信号获取基站信息，然后调用第三方公开的根据基站信息查找基站的经纬度值及地址信息（大概位置）。

一、通过手机信号获取基站信息（详细的可以参考：Android基站定位——通过手机信号获取基站信息（一））

[java] view plain copy

1. TelephonyManagermTelephonyManager=(TelephonyManager)getSystemService(Context.TELEPHONY_SERVICE);
3. //返回值MCC+MNC
4. Stringoperator=mTelephonyManager.getNetworkOperator();
5. mcc=Integer.parseInt(operator.substring(0,3));
6. mnc=Integer.parseInt(operator.substring(3));
8. //中国移动和中国联通获取LAC、CID的方式
9. GsmCellLocationlocation=(GsmCellLocation)mTelephonyManager.getCellLocation();
10. lac=location.getLac();
11. cid=location.getCid();
13. Log.i(TAG,"MCC="+mcc+"\tMNC="+mnc+"\tLAC="+lac+"\tCID="+cid);

二、调用第三方公开的API（根据基站信息查找基站的经纬度值及地址信息）

1、组拼JSON形式的请求参数

[java] view plain copy

1. /**
2. *获取JSON形式的基站信息
3. *@parammcc移动国家代码（中国的为460）
4. *@parammnc移动网络号码（中国移动为0，中国联通为1，中国电信为2）；
5. *@paramlac位置区域码
6. *@paramcid基站编号
7. *@returnjson
8. *@throwsJSONException
9. */
10. privateStringgetJsonCellPos(intmcc,intmnc,intlac,intcid)throwsJSONException{
11. JSONObjectjsonCellPos=newJSONObject();
12. jsonCellPos.put("version","1.1.0");
13. jsonCellPos.put("host","maps.google.com");
15. JSONArrayarray=newJSONArray();
16. JSONObjectjson1=newJSONObject();
17. json1.put("location_area_code",""+lac+"");
18. json1.put("mobile_country_code",""+mcc+"");
19. json1.put("mobile_network_code",""+mnc+"");
20. json1.put("age",0);
21. json1.put("cell_id",""+cid+"");
22. array.put(json1);
24. jsonCellPos.put("cell_towers",array);
25. returnjsonCellPos.toString();
26. }

2、通过HTTP协议网络请求源码：

[plain] view plain copy

1. requestURL:http://www.minigps.net/minigps/map/google/location
2. RequestMethod:POST
3. StatusCode:200OK
4. RequestHeadersviewsource
5. Accept:application/json,text/javascript,*/*;q=0.01
6. Accept-Charset:GBK,utf-8;q=0.7,*;q=0.3
7. Accept-Encoding:gzip,deflate,sdch
8. Accept-Language:zh-CN,zh;q=0.8
9. Connection:keep-alive
10. Content-Length:191
11. Content-Type:application/json;charset=UTF-8
12. Cookie:bdshare_firstime=1356366713546;JSESSIONID=68243935CD3355089CF07A3A22AAB372
13. Host:www.minigps.net
14. Origin:http://www.minigps.net
15. Referer:http://www.minigps.net/map.html
16. User-Agent:Mozilla/5.0(WindowsNT5.1)AppleWebKit/537.4(KHTML,likeGecko)Chrome/22.0.1229.94Safari/537.4
17. X-Requested-With:XMLHttpRequest
18. RequestPayload
19. {"cell_towers":[{"mobile_network_code":"1","location_area_code":"43018","cell_id":"11152773","age":0,"mobile_country_code":"460"}],"host":"maps.google.com","version":"1.1.0"}
21. ResponseHeadersviewsource
22. Content-Type:application/json
23. Date:Sat,03Jan201314:03:15GMT
24. Server:Apache-Coyote/1.1
25. Transfer-Encoding:chunked

3、用JAVA代码具体实现：

[java] view plain copy

1. /**
2. *调用第三方公开的API根据基站信息查找基站的经纬度值及地址信息
3. */
4. publicStringhttpPost(Stringurl,StringjsonCellPos)throwsIOException{
5. byte[]data=jsonCellPos.toString().getBytes();
6. URLrealUrl=newURL(url);
7. HttpURLConnectionhttpURLConnection=(HttpURLConnection)realUrl.openConnection();
8. httpURLConnection.setConnectTimeout(6*1000);
9. httpURLConnection.setDoOutput(true);
10. httpURLConnection.setDoInput(true);
11. httpURLConnection.setUseCaches(false);
12. httpURLConnection.setRequestMethod("POST");
13. httpURLConnection.setRequestProperty("Accept","application/json,text/javascript,*/*;q=0.01");
14. httpURLConnection.setRequestProperty("Accept-Charset","GBK,utf-8;q=0.7,*;q=0.3");
15. httpURLConnection.setRequestProperty("Accept-Encoding","gzip,deflate,sdch");
16. httpURLConnection.setRequestProperty("Accept-Language","zh-CN,zh;q=0.8");
17. httpURLConnection.setRequestProperty("Connection","Keep-Alive");
18. httpURLConnection.setRequestProperty("Content-Length",String.valueOf(data.length));
19. httpURLConnection.setRequestProperty("Content-Type","application/json;charset=UTF-8");
21. httpURLConnection.setRequestProperty("Host","www.minigps.net");
22. httpURLConnection.setRequestProperty("Referer","http://www.minigps.net/map.html");
23. httpURLConnection.setRequestProperty("User-Agent",
24. "Mozilla/5.0(WindowsNT5.1)AppleWebKit/537.4(KHTML,likeGecko)Chrome/22.0.1229.94Safari/537.4X-Requested-With:XMLHttpRequest");
26. httpURLConnection.setRequestProperty("X-Requested-With","XMLHttpRequest");
27. httpURLConnection.setRequestProperty("Host","www.minigps.net");
29. DataOutputStreamoutStream=newDataOutputStream(httpURLConnection.getOutputStream());
30. outStream.write(data);
31. outStream.flush();
32. outStream.close();
34. if(httpURLConnection.getResponseCode()==HttpURLConnection.HTTP_OK){
35. InputStreaminputStream=httpURLConnection.getInputStream();
36. returnnewString(read(inputStream));
37. }
38. returnnull;
39. }

4、读取返回的JSON数据流代码：

[java] view plain copy

1. /**
2. *读取IO流并以byte[]形式存储
3. *@paraminputSreamInputStream
4. *@returnbyte[]
5. *@throwsIOException
6. */
7. publicbyte[]read(InputStreaminputSream)throwsIOException{
8. ByteArrayOutputStreamoutStream=newByteArrayOutputStream();
9. intlen=-1;
10. byte[]buffer=newbyte[1024];
11. while((len=inputSream.read(buffer))!=-1){
12. outStream.write(buffer,0,len);
13. }
14. outStream.close();
15. inputSream.close();
17. returnoutStream.toByteArray();
18. }

三、请求参数及返回结果的JSON形式：

1、请求的JSON参数值：

[plain] view plain copy

1. {
2. "cell_towers":
3. [
4. {
5. "mobile_network_code":"1",
6. "location_area_code":"43018",
7. "cell_id":"11152773",
8. "age":0,
9. "mobile_country_code":"460"
10. }
11. ],
12. "host":"maps.google.com",
13. "version":"1.1.0"
14. }

2、返回的JSON结果值：

[plain] view plain copy

1. {
2. "location":
3. {
4. "latitude":"31.211389541625977",
5. "longitude":"121.60332489013672",
6. "address":
7. {"city":
8. "上海市浦东新区居里路432号;浦东新区光启安老院、第一三共制药上海公司、SUNPLUS[附近]",
9. "country":"",
10. "country_code":"",
11. "county":"",
12. "postal_code":"",
13. "region":"",
14. "street":"",
15. "street_number":""
16. }
17. },
18. "access_token":"dummytoken"
19. }

四、完整代码及所需权限：

在AndroidManifest.xml添加获取位置信息的权限：

[html] view plain copy

1. <uses-permissionandroid:name="android.permission.ACCESS_COARSE_LOCATION"/>
2. <uses-permissionandroid:name="android.permission.INTERNET"/>

五、测试网址：http://www.minigps.net/map.html

六、Google的基站定位http://www.google.com/loc/json或者http://www.google.com.hk/loc/json已不可用，访问返回404。官方给出的答复：https://developers.google.com/gears/?hl=zh-TW
