Aberdeen Security Defender Demo (ii)

First step: Start Tomcat and add the following JSON file to Tomcat

{"Version": "2.0", "description": "I am the latest, to download I put", "Apkurl": "http://192.168.1.103:8080/zaizaimobilesafe-2.0.apk"}

Step two: Implement a function to display the network access server to obtain the Server data function function

Private void chackupdate ()  {    /* defines a message object that is passed as a handler parameter for data transfer */     final message message = message.obtain ();     final  long starttime = system.currenttimemillis ();     new thread (new  runnable ()  {         @Override          public void run ()  {             try {                 /* In the value folder, configure a config. getstring file, store the URL of the server for ease of maintenance, because R.string.serviceurl represents an integer that is an identity of the data, not the data itself */                 url url =  new url (getString (r.string.serviceurl));                 httpurlconnection connection =  (httpurlconnection)   Url.openconnection ();                 connection.setrequestmethod ("GET");                 connection.setconnecttimeout (4000);                 int code =  Connection.getresponsecode ();                 if  (code == 200)  {                     /* Access Successful */                     inputstream is =  connection.getinputstream ();                     /* change the flow into string*/                      string result = streamtools.readfromstream (IS);       &NBSP;&NBSP;&NBSP;&NBSP;&NBSP;&NBSP;&NBSP;&NBSP;&NBSP;&NBSP;&NBSP;&NBSP;&NBSP;&NBSP;LOG.I (TAG,  "Networking Success"  + result);                     /*json parsing */                     JSONObject object = new  Jsonobject (Result);                     verison =  (String)  object.get ("Vsersion");                     description =  (String)   Object.get ("description");                     apkurl =  (String)  object.get ("Apkurl");                     /* Check if it is a new version */                     if  (Getversionname (). Equals (Verison))  {                          message.what = enter_home;                         /* version consistent, go to the main page */                     } else {                          message.what = SHOW_UPDATE_DIALOG;                         /* Update new version */                     }                 }             } catch  (Malformedurlexception e)  {                 message.what = url_error;                 e.printstAcktrace ();            } catch  ( Ioexception e)  {                 message.what = NETWORK_ERROR;                 e.printstacktrace ();             } catch  (jsonexception e)  {                 message.what = JSON_ERROR;                 e.printstacktrace ();             } finally {                 long endTime =  System.currenttimemillis ();  &nHow much time did bsp;              /* run */                 long dtime  = endTime - startTime;                 /* let the program stay for 2 seconds */                 if  (dtime < 4000)  {                     try {                          thread.sleep (4000 - dtime);                     } catch  ( Interruptedexception e)  {                         e.printstacktrace ();                     }                 }                 handler.sendmessage (message);             }        }    }). Start ();}

Define a handler to receive data

Private handler handler = new handler ()  {          @Override         public void handlemessage ( MESSAGE MSG)  {            switch  ( Msg.what)  {                 case show_update_dialog:/* displays the upgraded dialog box */                     LOG.I (tag,  "Show upgrade dialog box");                      Showupdatedialog ();                     break;                 case enter_home:/* into the main page */                     enterhome ();                     break;                 case url_error:/*url Error */                     enterhome ();                      Toast.maketext (Getapplicationcontext (),  "URL error",  toast.length_long). Show ();                     break;                 case network_ error:/* Network Error */  &Nbsp;                  Enterhome ();                     toast.maketext (Getapplicationcontext (),  "Network Exception",  toast.length_long). Show ();                      break;                 case json_error:/*json Parsing Error */                     enterhome ();                     toast.maketext ( Getapplicationcontext (),  "JSON parsing error",  toast.length_long). Show ();                     break;                 default:                     break;             }            super.handlemessage (msg);        }    };

The next pass will give the code for the Entryhome function and the main page.
