How to send an Email from your Android App?

Sending an email from your Android app can be accomplished using Intent. There are different ways to send emails, but the most common approach involves launching an email client installed on the user's device using an Intent.

Here's how you can implement this:

1. Using Intent:

The following code will allow users to select an email client installed on their device to send the email:

Intent emailIntent = new Intent(Intent.ACTION_SEND);
emailIntent.setType("text/plain");
emailIntent.putExtra(Intent.EXTRA_EMAIL, new String[] {"recipient@example.com"}); // recipients
emailIntent.putExtra(Intent.EXTRA_SUBJECT, "Email Subject");
emailIntent.putExtra(Intent.EXTRA_TEXT, "Email Body Text");

// Optionally, you can also attach files:
// emailIntent.putExtra(Intent.EXTRA_STREAM, Uri.parse("file:///sdcard/file_path"));

// Check if an Email client is installed and if yes, send the email
if (emailIntent.resolveActivity(getPackageManager()) != null) {
    startActivity(emailIntent);
} else {
    Toast.makeText(this, "No email client installed.", Toast.LENGTH_SHORT).show();
}

If you specifically want to send HTML formatted text in the email body, you can use:

emailIntent.setType("text/html");
emailIntent.putExtra(Intent.EXTRA_TEXT, Html.fromHtml("<p>This is a paragraph of <b>HTML</b> text.</p>"));

2. Using Libraries:

Another way to send emails directly from your app without user intervention is by using third-party libraries or services like JavaMail, but this requires SMTP setup and isn't recommended for sending sensitive or personal data. The user's credentials (or the email sending credentials) might be at risk, and Google might block sign-ins from the app for security reasons.

3. Backend Server:

A more secure approach for apps wanting to send email directly without user intervention is to use your backend server. Your app sends a request to your server, and the server handles the actual email sending. This keeps sensitive information, like SMTP credentials, on the server and not in the app.

Recommendations:

For most use-cases, using the Intent method is recommended because it provides the user with the choice and control over the email's content and recipients before sending.
If your app needs to send email in the background without user intervention, consider using a backend server. This is more secure and avoids exposing sensitive email credentials in your app's code.

Remember to add necessary permissions and configurations if you're attaching files or accessing other external resources.

How to implement email sending in Android:

Use Intent.ACTION_SEND to launch an email client in Android:

Intent emailIntent = new Intent(Intent.ACTION_SEND);
emailIntent.setType("text/plain");
emailIntent.putExtra(Intent.EXTRA_EMAIL, new String[]{"recipient@example.com"});
emailIntent.putExtra(Intent.EXTRA_SUBJECT, "Subject");
emailIntent.putExtra(Intent.EXTRA_TEXT, "Body of the email");

startActivity(Intent.createChooser(emailIntent, "Send Email"));

Android email intent example:

An example of using the email intent in Android:

Intent emailIntent = new Intent(Intent.ACTION_SEND);
emailIntent.setType("text/plain");
emailIntent.putExtra(Intent.EXTRA_EMAIL, new String[]{"recipient@example.com"});
emailIntent.putExtra(Intent.EXTRA_SUBJECT, "Subject");
emailIntent.putExtra(Intent.EXTRA_TEXT, "Body of the email");

startActivity(Intent.createChooser(emailIntent, "Send Email"));

Sending emails programmatically in Android:

Programmatically send emails using Intent.ACTION_SEND:

Intent emailIntent = new Intent(Intent.ACTION_SEND);
emailIntent.setType("text/plain");
emailIntent.putExtra(Intent.EXTRA_EMAIL, new String[]{"recipient@example.com"});
emailIntent.putExtra(Intent.EXTRA_SUBJECT, "Subject");
emailIntent.putExtra(Intent.EXTRA_TEXT, "Body of the email");

startActivity(Intent.createChooser(emailIntent, "Send Email"));

Using Intent.ACTION_SEND for email in Android app:

Utilize Intent.ACTION_SEND to implement email sending functionality:

Intent emailIntent = new Intent(Intent.ACTION_SEND);
emailIntent.setType("text/plain");
emailIntent.putExtra(Intent.EXTRA_EMAIL, new String[]{"recipient@example.com"});
emailIntent.putExtra(Intent.EXTRA_SUBJECT, "Subject");
emailIntent.putExtra(Intent.EXTRA_TEXT, "Body of the email");

startActivity(Intent.createChooser(emailIntent, "Send Email"));

Email sending functionality in Android development:

Add email sending functionality to your Android app using Intent.ACTION_SEND:

Intent emailIntent = new Intent(Intent.ACTION_SEND);
emailIntent.setType("text/plain");
emailIntent.putExtra(Intent.EXTRA_EMAIL, new String[]{"recipient@example.com"});
emailIntent.putExtra(Intent.EXTRA_SUBJECT, "Subject");
emailIntent.putExtra(Intent.EXTRA_TEXT, "Body of the email");

startActivity(Intent.createChooser(emailIntent, "Send Email"));

Sending emails from Android app with Intent.ACTION_SENDTO:

Use Intent.ACTION_SENDTO for sending emails:

Intent emailIntent = new Intent(Intent.ACTION_SENDTO);
emailIntent.setData(Uri.parse("mailto:recipient@example.com"));
emailIntent.putExtra(Intent.EXTRA_SUBJECT, "Subject");
emailIntent.putExtra(Intent.EXTRA_TEXT, "Body of the email");

startActivity(Intent.createChooser(emailIntent, "Send Email"));

Implementing email sending feature in Android Studio:

Implement email sending feature in Android Studio using Intent.ACTION_SEND:

Intent emailIntent = new Intent(Intent.ACTION_SEND);
emailIntent.setType("text/plain");
emailIntent.putExtra(Intent.EXTRA_EMAIL, new String[]{"recipient@example.com"});
emailIntent.putExtra(Intent.EXTRA_SUBJECT, "Subject");
emailIntent.putExtra(Intent.EXTRA_TEXT, "Body of the email");

startActivity(Intent.createChooser(emailIntent, "Send Email"));
