How to receive mail message from mail in android studio

To receive mail messages in an Android app using Android Studio, you'll need to use the JavaMail API or a third-party library like Apache Commons Email. Here's a step-by-step guide to help you get started:

Option 1: Using JavaMail API

Add the JavaMail API to your project:
- In your Android Studio project, go to File > Project Structure > Modules > Dependencies.
- Click the + button and select Library > Java > JavaMail API.
- Follow the installation instructions to add the JavaMail API to your project.
Create a new Java class to handle email reception:
- Create a new Java class, e.g., EmailReceiver.java.
- Import the necessary classes: javax.mail, javax.mail.internet, and javax.mail.util.
Set up the email receiver:
- Create a Properties object to store email settings (e.g., server, port, username, password).
- Create a Session object using the Properties object.
- Create a Store object using the Session object.
- Create a Folder object to store incoming emails.
Listen for new emails:
- Use a Folder object's addMessageCountListener() method to listen for new emails.
- Implement the MessageCountListener interface to handle new email arrivals.
Process incoming emails:
- Use the Message object to retrieve email details (e.g., subject, body, attachments).
- Process the email as needed (e.g., display the email in a UI component).

Here's some sample code to get you started:

import javax.mail.*;
import javax.mail.internet.*;
import java.util.Properties;

public class EmailReceiver {
    private static final String EMAIL_SERVER = "your_email_server";
    private static final int EMAIL_PORT = 587;
    private static final String EMAIL_USERNAME = "your_email_username";
    private static final String EMAIL_PASSWORD = "your_email_password";

    public EmailReceiver() {
        Properties props = new Properties();
        props.put("mail.store.protocol", "imaps");
        props.put("mail.imaps.host", EMAIL_SERVER);
        props.put("mail.imaps.port", EMAIL_PORT);
        props.put("mail.imaps.username", EMAIL_USERNAME);
        props.put("mail.imaps.password", EMAIL_PASSWORD);

        Session session = Session.getInstance(props);
        Store store = session.getStore();
        Folder folder = store.getFolder("INBOX");

        folder.addMessageCountListener(new MessageCountListener() {
            @Override
            public void messagesAdded(Folder folder, int count) {
                // Handle new email arrivals
                Message[] messages = folder.getMessages();
                for (Message message : messages) {
                    // Process the email
                    String subject = message.getSubject();
                    String body = message.getContent().toString();
                    //...
                }
            }
        });
    }
}

Option 2: Using Apache Commons Email

Add the Apache Commons Email library to your project:
- In your Android Studio project, go to File > Project Structure > Modules > Dependencies.
- Click the + button and select Library > Java > Apache Commons Email.
- Follow the installation instructions to add the Apache Commons Email library to your project.
Create a new Java class to handle email reception:
- Create a new Java class, e.g., EmailReceiver.java.
- Import the necessary classes: org.apache.commons.email.
Set up the email receiver:
- Create a Email object to receive emails.
- Set the email server, port, username, and password using the Email object's setter methods.
Listen for new emails:
- Use the Email object's addMessageListener() method to listen for new emails.
- Implement the MessageListener interface to handle new email arrivals.
Process incoming emails:
- Use the Message object to retrieve email details (e.g., subject, body, attachments).
- Process the email as needed (e.g., display the email in a UI component).

Here's some sample code to get you started:

import org.apache.commons.email.Email;
import org.apache.commons.email.Message;
import org.apache.commons.email.MessageListener;

public class EmailReceiver {
    private static final String EMAIL_SERVER = "your_email_server";
    private static final int EMAIL_PORT = 587;
    private static final String EMAIL_USERNAME = "your_email_username";
    private static final String EMAIL_PASSWORD = "your_email_password";

    public EmailReceiver() {
        Email email = new Email();
        email.setServer(EMAIL_SERVER);
        email.setPort(EMAIL_PORT);
        email.setUsername(EMAIL_USERNAME);
        email.setPassword(EMAIL_PASSWORD);

        email.addMessageListener(new MessageListener() {
            @Override
            public void messageReceived(Message message) {
                // Handle new email arrivals
                String subject = message.getSubject();
                String body = message.getContent().toString();
                //...
            }
        });
    }
}

Remember to replace the placeholders (your_email_server, your_email_username, your_email_password) with your actual email server, username, and password.

In both options, you'll need to handle exceptions and errors that may occur during email reception. Additionally, you may want to consider implementing email filtering or processing rules to handle incoming emails more efficiently.
