The error message “Email Intent Value Not Set ‘TO’ : address” typically occurs in Android when attempting to launch an email intent without specifying the recipient (TO) address.

When using an email intent in Android to open an email client for sending an email, you need to ensure that you set the recipient address (TO), subject, and body of the email. If any of these essential fields are missing, you may encounter this error.

Here’s how you can set the recipient address (TO) in an email intent in Android:

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

In this code snippet:

• Intent.ACTION_SEND specifies that we want to send data to someone else.
• "message/rfc822" indicates that the intent is for sending an email.
• Intent.EXTRA_EMAIL is used to specify the recipient email address. You should replace "recipient@example.com" with the actual email address.
• Intent.EXTRA_SUBJECT is used to specify the subject of the email.
• Intent.EXTRA_TEXT is used to specify the body of the email.
• startActivity(Intent.createChooser(intent, "Send Email")) starts the activity for sending an email and allows the user to choose from available email clients.

Ensure that you provide a valid email address for the recipient (TO) field to avoid encountering the “Email Intent Value Not Set ‘TO’ : address” error.
