Android: Retrieving Password via registered Email on My Server

Question

i am working on retrieving password to the user when he submits his mail id that he registered on my server. I need to check whether he entered correct registered id and give him response by sending password to his corresponding mail and set dialog as password sent to your mail or if he entered wrong mail id i have to show mail id not registered... Any Idea? This is my code...

             package com.soap;

Fallow these step then you got your answer.

1-: Parse your response ans store in a local variable like int resTemp=0;

2-:Use the given blow code accordingly.

    if(resTemp==1)
                        {
                            AlertDialog.Builder successfullyLogin = new Builder(LoginActivity.this);
                            successfullyLogin.setCancelable(false);
                            successfullyLogin.setMessage("Successfully Login !");
                            successfullyLogin.setPositiveButton("Ok",new DialogInterface.OnClickListener() 
                            {
                                public void onClick(DialogInterface dialog,int which) 
                                {
                                    finish();
                                    startActivity(new Intent(LoginActivity.this,MainMenuActivity.class));
                                }
                            });
                            successfullyLogin.show();


                        }
   else if(resTemp==-1){

                            AlertDialog.Builder unsuccessfullyLogin = new Builder(LoginActivity.this);
                            unsuccessfullyLogin.setCancelable(false);
                            unsuccessfullyLogin.setMessage("Invalid Username or Password !");
                            unsuccessfullyLogin.setPositiveButton("TryAgain",new DialogInterface.OnClickListener() 
                            {
                                public void onClick(DialogInterface dialog,int which) 
                                {
                                    etLoginUserName.setText("");
                                    etLoginPassword.setText("");
                                    etLoginUserName.requestFocus();
                                }
                            });
                            unsuccessfullyLogin.setNeutralButton("Forgot Password",new DialogInterface.OnClickListener() 
                            {
                                public void onClick(DialogInterface dialog,int which) 
                                {

                                }
                            });

                            unsuccessfullyLogin.show();

                        }

I hope it is useful to you.
