How to send mail in android

Sending mail in Android can be done using the Android's built-in Intent system. Here's a step-by-step guide on how to send a mail in Android:

Method 1: Using the Android's built-in Intent

Create a new Intent object:

Intent intent = new Intent(Intent.ACTION_SEND);

Set the type of the intent to "message/rfc822" which is the MIME type for email:
```
intent.setType("message/rfc822");
```

Set the recipient's email address:

intent.putExtra(Intent.EXTRA_EMAIL, new String[] {"[email protected]"});

Set the subject of the email:

intent.putExtra(Intent.EXTRA_SUBJECT, "Subject of the email");

Set the body of the email:

intent.putExtra(Intent.EXTRA_TEXT, "Body of the email");

Start the intent:
```
startActivity(Intent.createChooser(intent, "Send Email"));
```
This will open the default email client on the device and allow the user to send the email.

Method 2: Using a third-party library

You can also use a third-party library such as JavaMail or Apache Commons Email to send mail in Android. Here's an example of how to use JavaMail:

Add the JavaMail library to your project:

dependencies {
 implementation 'com.sun.mail:android-mail:1.6.2'
}

Create a new instance of the GmailTransport class:

GmailTransport transport = new GmailTransport();

Set the recipient's email address:

transport.setRecipient(new InternetAddress("[email protected]"));

Set the subject of the email:

transport.setSubject("Subject of the email");

Set the body of the email:

transport.setTextBody("Body of the email");

Send the email:
```
transport.send();
```
Note: You need to have the necessary permissions to send email in your AndroidManifest.xml file:
```
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.SEND_SMS" />
```
Also, you need to have a valid email account set up on the device for the email to be sent successfully.

Example Code

Here's an example code that demonstrates how to send a mail in Android using the Android's built-in Intent:

Intent intent = new Intent(Intent.ACTION_SEND);
intent.setType("message/rfc822");
intent.putExtra(Intent.EXTRA_EMAIL, new String[] {"[email protected]"});
intent.putExtra(Intent.EXTRA_SUBJECT, "Subject of the email");
intent.putExtra(Intent.EXTRA_TEXT, "Body of the email");
startActivity(Intent.createChooser(intent, "Send Email"));

And here's an example code that demonstrates how to send a mail in Android using JavaMail:

GmailTransport transport = new GmailTransport();
transport.setRecipient(new InternetAddress("[email protected]"));
transport.setSubject("Subject of the email");
transport.setTextBody("Body of the email");
transport.send();
