This is it. I promise.
ACTION_TECHNOLOGY_DISCOVERED -> ACTION_TECH_DISCOVERED
This was missed in our technology->tech rename.
Hide TagTechnology.reconnect()
This is used to reset any per-connection state in a tag, by reconnecting
to it. The first problem is that it belongs on Tag, not TagTechnology. The
second problem is that it may become redundant once we add Tag.rediscover()
which will also reconnect to the tag, and will also return a new Tag with
newly created technologies enumerated. And the third and most significant
problem is that you can already achieve the same result by just calling
close() followed by connect().
Hide Tag.createMockTag()
This API cannot be used reliably. First it requires using int[] for the
technology list, but those int constants are now hidden. Second it requires
knowledge of the extras parcel used to fill technology specific data - also
not public.
Introduce TagTechnology.isConnected()
Every child class already impelmented this, and given that connect() and
close() are defined on the interface, then isConnected() should be there
too.
Modify Ndef.getType to return a string (not int)
Allows more flexibility in adding new NDEF types. Current public strings are
org.nfcforum.ndef.type1
org.nfcforum.ndef.type2
org.nfcforum.ndef.type3
org.nfcforum.ndef.type4
com.nxp.ndef.mifareclassic
Add NdefFormatable.formatReadOnly()
This allows you to make the tag read-only at the same time as performing
format and write. It is important because we currently don't have any
public API to re-enumerate a tag technology list after making a tag
NDEF compatible, so you can't perform the format as a seperate step
without physically removing the tag from field and returning it.
Modify Readonly -> ReadOnly
Make Tag class final
