How to check whether NFC is enabled or not in android?

Question

How can i check whether NFC is enabled or not programmatically? Is there any way to enable the NFC on the device from my program? Please help me

Answer 1

I might be a little late here, but I've implemented a 'complete' example with detection of

1. NFC capability (hardware), and
2. Initial NFC state (enabled or disabled in settings), and
3. Changes to the state

I've also added a corresponding Beam example which uses the

nfcAdapter.isNdefPushEnabled()

method introduced in later Android versions to detect beam state like in 2) and 3).
