all bit of code need add if password != password2 abort register, im unsure of how that, can please assit me?

    httpclient=new defaulthttpclient();     httppost= new httppost("http://purelymean.com/android/adduser.php"); // make sure url correct.     //add data     namevaluepairs = new arraylist<namevaluepair>(4);     // use same variable name posting i.e android side variable name , php side variable name should similar,      namevaluepairs.add(new basicnamevaluepair("username",usern.gettext().tostring().trim()));  // $edittext_value = $_post['edittext_value'];     namevaluepairs.add(new basicnamevaluepair("password",password.gettext().tostring().trim()));      namevaluepairs.add(new basicnamevaluepair("password2",password2.gettext().tostring().trim()));      namevaluepairs.add(new basicnamevaluepair("email",email.gettext().tostring().trim()));       if (password != password2) {         toast.maketext(register.this,"passwords dont match",toast.length_short).show();      }      httppost.setentity(new urlencodedformentity(namevaluepairs));     //execute http post request     response=httpclient.execute(httppost);     // edited james coderzheaven.. here....     responsehandler<string> responsehandler = new basicresponsehandler();     final string response = httpclient.execute(httppost, responsehandler);     system.out.println("response : " + response);      runonuithread(new runnable() {         public void run() {             tv.settext("response php : " + response);             dialog.dismiss();         }     }); 

don't use password != password2 comparing strings.to compare strings use string1.equals(string2). if condition false toast passwords not match , cancel registration.

if (!(password.equals(password2))) {    toast.maketext(register.this,"passwords dont match",toast.length_short).show(); }
