How to create Forgot password in android?

Question

I want an app in which i use Forgot Password. I have a TextView, named forgot password. When i click on it, It shows a PopUp having edittext in which i can write Email Adrress and when i click on OK button it sent new passward on my mail id. I use JSSEProvider class for protocols.

public final class JSSEProvider extends Provider {

public JSSEProvider() {
    super("HarmonyJSSE", 1.0, "Harmony JSSE Provider");
    AccessController.doPrivileged(new java.security.PrivilegedAction<Void>() {
        public Void run() {
            put("SSLContext.TLS",
                    "org.apache.harmony.xnet.provider.jsse.SSLContextImpl");
            put("Alg.Alias.SSLContext.TLSv1", "TLS");
            put("KeyManagerFactory.X509",
                    "org.apache.harmony.xnet.provider.jsse.KeyManagerFactoryImpl");
            put("TrustManagerFactory.X509",
                    "org.apache.harmony.xnet.provider.jsse.TrustManagerFactoryImpl");
            return null;
        }
    });
}
}

public class GMailSender extends javax.mail.Authenticator {

Answer 1

I would suggest you to make a simple button and make the background transparent using #00000000 and make text of button whichever color you want...boom!!! you have your Forgot Password.

Answer 2

1. Pass Cus_email as parameter from android java file.
2. make a webservice and host this on server

hope this sample code work for you...

        <?php
    if (isset($_POST['cus_email']))
    {
    $cus_email = $_POST['cus_email'];
    $ans = mysql_query("SELECT cus_pass from customer where cus_email='$cus_email'") or die(mysql_error());
    $to = $_POST['cus_email'];
    $cus_mail = 'support@xyz.in';

    $cus_sub = 'Your Recovery password';
    $cus_msg = 'this is your password'.$ans;


    $headers  = 'MIME-Version: 1.0' . "\r\n";
    $headers .= 'Content-type: text/html; charset=iso-8859-1' . "\r\n";
    $headers .= "From: ".$cus_mail.""."\r\n";

    mail($to,$cus_sub,$cus_msg,$headers);
    if(mail)
    {
      echo "1";
    }
    else
    {
      echo "0";
    }

    }
    ?>

Answer 3

Try this very simple function..

    protected void sendEmail() {
      Log.i("Send email", "");

      String[] TO = {"amrood.admin@gmail.com"};
      String[] CC = {"mcmohd@gmail.com"};
      Intent emailIntent = new Intent(Intent.ACTION_SEND);
      emailIntent.setData(Uri.parse("mailto:"));
      emailIntent.setType("text/plain");


      emailIntent.putExtra(Intent.EXTRA_EMAIL, TO);
      emailIntent.putExtra(Intent.EXTRA_CC, CC);
      emailIntent.putExtra(Intent.EXTRA_SUBJECT, "Your subject");
      emailIntent.putExtra(Intent.EXTRA_TEXT, "Email message goes here");

      try {
         startActivity(Intent.createChooser(emailIntent, "Send mail..."));
         finish();
         Log.i("Finished sending email...", "");
      } catch (android.content.ActivityNotFoundException ex) {
         Toast.makeText(MainActivity.this, 
         "There is no email client installed.", Toast.LENGTH_SHORT).show();
      }
   }

Add your Password and other Text as Intent.EXTRA_TEXT's value..
