In this post, I will show you how to read and write an NFC tag on an Android device. We would be using Android’s NFC capabilities to read and write a tag.
NFC tags come in a wide array of technologies and can also have data written to them in many different ways. Android has the most support for the NDEF standard, which is defined by the NFC Forum. NDEF data is encapsulated inside a message (NdefMessage) that contains one or more records (NdefRecord).In order to understand NFC, you need to know about the NFC Data Exchange Format (NDEF), which is the lingua franca for NFC devices and tags. In this chapter, you’ll learn about the structure of NDEF and the records it carries. NFC Intents can have three different actions depending on the data contained in the tag: ACTION_NDEF_DISCOVERED: When the tag contains data in NDEF format and a known type; ACTION_TECH_DISCOVERED: When the tag does not contain data in NDEF format or that cannot be mapped to known types;NFC Data Exchange Format (NDEF) NDEF is a standardized data format specification by the NFC Forum which is used to describe how a set of actions are to be encoded onto a NFC tag or to be exchanged between two active NFC devices.
I'm trying to create an NFC tag that will trigger two separate actions: open a Bluetooth connection. launching an app (or going to the play store) I've used nfc-eclipse-plugin to create a message containing two suitable records, however, when written to a tag, it always only triggers the first action.

Encapsulating the MIME type or URI and the payload into an intent. These first two steps are described in How NFC tags are mapped to MIME types and URIs. Starts an activity based on the intent.
Work with supported tag technologies. When working with NFC tags and Android-powered devices, the main format you use to read and write data on tags is NDEF. When a device scans a tag with NDEF data, Android provides support in parsing the message and delivering it in an NdefMessage when possible. NFC tags like MIFARE Classic® cards can be configured as NDEF tags and data written on those cards by an NFC device can be understood and you can access it with any other device compliant with NDEF. NDEF messages can be exchanged in peer-to-peer mode between two NFC devices.Read and Write NDEF messages on NFC Tags with Arduino. NFC Data Exchange Format (NDEF) is a common data format that operates across all NFC devices, regardless of the underlying tag or device technology.
