Android access to PHP retrieve JSON data

PHP Code ============================

$array = Array ( 
   
  ' username ' => ' Yang Ji ', ' 
   
  password ' => ' 123456 ', 
   
  ' user_id ' =>1 
   
); 
   
   
echo Json_encode ($array);

Java Code ============================

private void Starturlcheck (String username,string password) {httpclient client = new Defaulthttpclient (); 
   
    
   
StringBuilder builder = new StringBuilder (); 
   
HttpGet myget = new HttpGet ("http://10.0.2.2/Android/index.php"); 
   
try {httpresponse response = Client.execute (Myget); 
   
BufferedReader reader = new BufferedReader (New InputStreamReader (Response.getentity (). GetContent ())); 
   
for (String s = reader.readline (); s!= null; s = Reader.readline ()) {builder.append (s); 
   
} jsonobject jsonobject = new Jsonobject (builder.tostring ()); 
   
String re_username = jsonobject.getstring ("username"); 
   
String Re_password = jsonobject.getstring ("password"); 
   
int re_user_id = Jsonobject.getint ("user_id"); 
   
Settitle ("User id_" +re_user_id); 
   
LOG.V ("url response", "true=" +re_username); 
   
LOG.V ("url response", "true=" +re_password); 
   
catch (Exception e) {log.v ("url response", "false"); 
   
E.printstacktrace (); }
   
} 

Run Results ===================================

Where http://10.0.2.2 is the IP address of the native URL for Android access. http://127.0.0.1 for testing on the computer

An exception is thrown when code is executed php100.com

Java.net.SocketException:Permission denied

This is not sufficient for application access to the network in Androidmanifest.xml, the following configuration is required:

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

is added to

</manifest>

It was good before.

Then the test passes.
