Android sent mail with image
To send an email with an image attachment from an Android app, you can use the JavaMail API or a third-party library like SendGrid or Firebase Cloud Messaging. Here's an example of how to do it using JavaMail API:
Step 1: Add the JavaMail API to your project
Add the following dependencies to your Android project's build.gradle
file:
dependencies {
implementation 'com.sun.mail:android-mail:1.6.2'
implementation 'com.sun.mail:android-transport:1.6.2'
}
Step 2: Create a JavaMail session
Create a JavaMail session object:
Properties props = new Properties();
props.put("mail.smtp.host", "your-smtp-host");
props.put("mail.smtp.port", "your-smtp-port");
props.put("mail.smtp.auth", "true");
props.put("mail.smtp.starttls.enable", "true");
Session session = Session.getInstance(props, new Authenticator() {
@Override
protected PasswordAuthentication getPasswordAuthentication() {
return new PasswordAuthentication("your-email", "your-password");
}
});
Step 3: Create a MimeMessage object
Create a MimeMessage object to represent the email:
MimeMessage message = new MimeMessage(session);
message.setFrom(new InternetAddress("your-email"));
message.setRecipient(Message.RecipientType.TO, new InternetAddress("recipient-email"));
message.setSubject("Email with image attachment");
Step 4: Add the image attachment
Add the image attachment to the email:
File file = new File("/path/to/image.jpg");
DataSource source = new FileDataSource(file);
message.setDataHandler(new DataHandler(source));
message.setFileName(file.getName());
Step 5: Send the email
Send the email using the JavaMail API:
Transport.send(message);
Here's the complete code:
import android.os.Bundle;
import android.util.Log;
import javax.mail.*;
import javax.mail.internet.InternetAddress;
import javax.mail.internet.MimeMessage;
import java.io.File;
import java.io.IOException;
import java.util.Properties;
public class MainActivity extends AppCompatActivity {
private static final String TAG = "MainActivity";
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
// Create a JavaMail session
Properties props = new Properties();
props.put("mail.smtp.host", "your-smtp-host");
props.put("mail.smtp.port", "your-smtp-port");
props.put("mail.smtp.auth", "true");
props.put("mail.smtp.starttls.enable", "true");
Session session = Session.getInstance(props, new Authenticator() {
@Override
protected PasswordAuthentication getPasswordAuthentication() {
return new PasswordAuthentication("your-email", "your-password");
}
});
// Create a MimeMessage object
MimeMessage message = new MimeMessage(session);
message.setFrom(new InternetAddress("your-email"));
message.setRecipient(Message.RecipientType.TO, new InternetAddress("recipient-email"));
message.setSubject("Email with image attachment");
// Add the image attachment
File file = new File("/path/to/image.jpg");
DataSource source = new FileDataSource(file);
message.setDataHandler(new DataHandler(source));
message.setFileName(file.getName());
// Send the email
Transport.send(message);
Log.d(TAG, "Email sent successfully!");
}
}
Make sure to replace the placeholders (your-smtp-host
, your-smtp-port
, your-email
, your-password
, and recipient-email
) with your actual email settings and recipient's email address.
Also, note that this is just a basic example, and you may need to add additional error handling and configuration depending on your specific use case.
