public class androidhttprequestsactivity extends activity implements onclicklistener {      private edittext usernameedittext;     private edittext passwordedittext;     private button sendgetreqbutton;      /** called when activity first created. */     @override     public void oncreate(bundle savedinstancestate) {         super.oncreate(savedinstancestate);         setcontentview(r.layout.main);          usernameedittext = (edittext) findviewbyid(r.id.main_username_edittext);         passwordedittext = (edittext) findviewbyid(r.id.main_password_edittext);          sendgetreqbutton = (button) findviewbyid(r.id.main_sendgetreq_button);         sendgetreqbutton.setonclicklistener(this);     }      public void onclick(view v) {          if(v.getid() == r.id.main_sendgetreq_button) {             // values given in edittext fields             string givenusername = usernameedittext.gettext().tostring();             string givenpassword = passwordedittext.gettext().tostring();             system.out.println("given usernames :" + givenusername + " given password :" + givenpassword);              // pass values connectwithhttpget() method             connectwithhttpget(givenusername, givenpassword);         }             }      private void connectwithhttpget(string givenusername, string givenpassword) {          class httpgetasynctask extends asynctask<string, void, string> {              @override             protected string doinbackground(string... params) {                  string email = params[0];                 string pwd = params[1];                 system.out.println("email :" + email + " pwd :" + pwd);                   httpclient httpclient = new defaulthttpclient();                   httpget httpget = new httpget("http://ipadress/folder/filename.php?command=cmd_login&email=name&pwd=00");                  try {                     httpresponse httpresponse = httpclient.execute(httpget);                     system.out.println("httpresponse");                     // comes httpresponse                     inputstream inputstream = httpresponse.getentity().getcontent();                      inputstreamreader inputstreamreader = new inputstreamreader(inputstream);                      bufferedreader bufferedreader = new bufferedreader(inputstreamreader);                     stringbuilder stringbuilder = new stringbuilder();                     string bufferedstrchunk = null;                      while((bufferedstrchunk = bufferedreader.readline()) != null){                         stringbuilder.append(bufferedstrchunk);                     }                     system.out.println("returning value of doinbackground :" + stringbuilder.tostring());                      return stringbuilder.tostring();                 } catch (clientprotocolexception cpe) {                     system.out.println("exception generates caz of httpresponse :" + cpe);                     cpe.printstacktrace();                 } catch (ioexception ioe) {                     system.out.println("second exception generates caz of httpresponse :" + ioe);                     ioe.printstacktrace();                 }                  return null;             }              @override             protected void onpostexecute(string result) {                 super.onpostexecute(result);                  if(result.equals("1"))                 {                      toast.maketext(getapplicationcontext(), "http working...", toast.length_long).show();                 }else{                     toast.maketext(getapplicationcontext(), "invalid...", toast.length_long).show();                 }             }         }          httpgetasynctask httpgetasynctask = new httpgetasynctask();          httpgetasynctask.execute(givenusername, givenpassword);      } } 

and response in logcat this. how match result value show login sucess

if(result.equal("")) 

what should compare result? tried value==1, doesn't work.

you can possibly check 2 states of request

• http response code
  • check if data returned ´http 200 ok´
• data check
  • deserialize response (simplexml, jackson json or fasterxml project)
  • check deserialization status (if model changed or response empty, fail)
  • match fields in deserialized object conditions
