NdefRecord mimeRecord = NdefRecord.createMime("text/plain", remainingString.getBytes(Charset.forName("US-ASCII")));
ndef.writeNdefMessage(new NdefMessage(mimeRecord));

This for launch application.

NdefRecord[] records = {NdefRecord.createApplicationRecord("com.demo.abc"),

but i dont understand how to write email content.

Answer 1

you could write two records , the first one is uri_record and second one is text_record

you could write in the first one the email address and in second one the text.

NdefRecord uri_record = NdefRecord.createUri("https://abc.defg.hi");
String text = "Here is the email content";

NdefRecord text_record= NdefRecord.createMime("text/plain", text.getBytes(Charset.forName("US-ASCII")));
NdefRecord[] records = {uri_record , text_record};
NdefMessage message = new NdefMessage(records);
ndef.connect();
ndef.writeNdefMessage(message);
ndef.close();

Answer 2

for write email data

NdefRecord mimeRecord = NdefRecord.createUri("mailto:" + "abc@gmail.com" + "?body=" + "your email message");
ndef.writeNdefMessage(new NdefMessage(mimeRecord));

Understand carefully

NdefRecord.createUri("mailto:" + "abc@gmail.com") 

write if you want to write only receiver email id into NFC tag

NdefRecord.createUri("mailto:" + "abc@gmail.com" + "?body=" + "your email message")

write if you want to write receiver email id and message into NFC tag

NdefRecord mimeRecord = NdefRecord.createUri("mailto:" + "abc@gmail.com" + "?subject=" + "your email subject" + "&body=" + "your email message")

write if you want to write receiver email id, email subject and message into NFC tag
