I am making an app that sends email to my group when the user will press submit button without opening gmail but the app crashes just after the screen in the pic:-
This is where I declare what happens when the button is pressed:-
Button submit=(Button) findViewById(R.id.rSubmit);
submit.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
String email,subject,message;
email="the_email_id_of_receiver";
subject="Test";
message="This is a test";
SendMail sm = new SendMail(RequestBlood.this, email, subject, message);
sm.execute();
}
});
The is the class that handles the task of sending mail:-
package org.bloodconnect.bloodconnect;
import android.app.ProgressDialog;
import android.content.Context;
import android.os.AsyncTask;
import android.widget.Toast;
import java.util.Properties;
import javax.mail.Message;
import javax.mail.MessagingException;
import javax.mail.PasswordAuthentication;
import javax.mail.Session;
import javax.mail.Transport;
import javax.mail.internet.InternetAddress;
import javax.mail.internet.MimeMessage;
//Class is extending AsyncTask because this class is going to perform a networking operation
public class SendMail extends AsyncTask<Void,Void,Void> {
private Context context;
private Session session;
//Information to send email
private String email;
private String subject;
private String message;
//Progressdialog to show while sending email
private ProgressDialog progressDialog;
//Class Constructor
public SendMail(Context context, String email, String subject, String message){
//Initializing variables
this.context = context;
this.email = email;
this.subject = subject;
this.message = message;
}
@Override
protected void onPreExecute() {
super.onPreExecute();
//Showing progress dialog while sending email
progressDialog = ProgressDialog.show(context,"Sending message","Please wait...",false,false);
}
@Override
protected void onPostExecute(Void aVoid) {
super.onPostExecute(aVoid);
//Dismissing the progress dialog
progressDialog.dismiss();
//Showing a success message
Toast.makeText(context,"Message Sent",Toast.LENGTH_LONG).show();
}
@Override
protected Void doInBackground(Void... params) {
//Creating properties
Properties props = new Properties();
//Configuring properties for gmail
//If you are not using gmail you may need to change the values
props.put("mail.smtp.host", "smtp.gmail.com");
props.put("mail.smtp.socketFactory.port", "465");
props.put("mail.smtp.socketFactory.class", "javax.net.ssl.SSLSocketFactory");
props.put("mail.smtp.auth", "true");
props.put("mail.smtp.port", "465");
//Creating a new session
session = Session.getDefaultInstance(props,
new javax.mail.Authenticator() {
//Authenticating the password
protected PasswordAuthentication getPasswordAuthentication() {
return new PasswordAuthentication(Config.EMAIL, Config.PASSWORD);
}
});
try {
//Creating MimeMessage object
MimeMessage mm = new MimeMessage(session);
//Setting sender address
mm.setFrom(new InternetAddress(Config.EMAIL));
//Adding receiver
mm.addRecipient(Message.RecipientType.TO, new InternetAddress(email));
//Adding subject
mm.setSubject(subject);
//Adding message
mm.setText(message);
//Sending email
Transport.send(mm);
} catch (MessagingException e) {
e.printStackTrace();
}
return null;
}
}
This is the class where I declare my id and password:-
package org.bloodconnect.bloodconnect;
public class Config {
public static final String EMAIL ="my_email_id";
public static final String PASSWORD ="password";
}
As it can be seen in the pic, unitl the onPreExecute method in SendMail class, everything is running fine (I hope so). I am pretty new to android so please help me fix this error. Thanks in advance :)
Logcat is in 2nd pic.
