How to retrieve json data by accessing php on Android

1. [Code] php code
1 $ array = array (

2 'username' => 'yangzhu ',

3 'Password' => '123 ',

4 'user _ id' => 1

5 );

6 echo json_encode ($ array );

2. [Code] java code
01 private void startUrlCheck (String username, String password)

02 {

03 HttpClient client = new DefaultHttpClient ();

04 StringBuilder builder = new StringBuilder ();

05

06 HttpGet myget = new HttpGet ("http: // 10.0.2.2/Android/index. php ");

07 try {

08 HttpResponse response = client.exe cute (myget );

09 BufferedReader reader = new BufferedReader (new InputStreamReader (

10 response. getEntity (). getContent ()));

11 for (String s = reader. readLine (); s! = Null; s = reader. readLine ()){

12 builder. append (s );

13}

14 JSONObject jsonObject = new JSONObject (builder. toString ());

15 String re_username = jsonObject. getString ("username ");

16 String re_password = jsonObject. getString ("password ");

17 int re_user_id = jsonObject. getInt ("user_id ");

18 setTitle ("User ID _" + re_user_id );

19 Log. v ("url response", "true =" + re_username );

20 Log. v ("url response", "true =" + re_password );

21} catch (Exception e ){

22 Log. v ("url response", "false ");

23 e. printStackTrace ();

24}

25}

3. [Code] running instructions
01 http: // 10.0.2.2 is the IP address used by Android to access the local url. Http: // 127.0.0.1 tested on the computer

02

03 An exception will be thrown during code execution.

04

05 java.net. SocketException: Permission denied

06

07 in AndroidManifest. xml, the following configuration is required:

08 <uses-permission Android: name = "android. permission. INTERNET"/>

Add in 09

It was good before 11.

12. Then the test passes.
