class
NfcManager
extends Object
High level manager used to obtain an instance of an NfcAdapter.
Use Context.getSystemService(java.lang.String)
with Context.NFC_SERVICE to create an NfcManager,
then call getDefaultAdapter() to obtain the NfcAdapter.
Alternately, you can just call the static helper
NfcAdapter.getDefaultAdapter(android.content.Context).
