[android-developers] Re: NFC send Photo

Sorry, I was interrupted and sent this out prematurely.

Anyway, that's the standard. Then you need to consider what the library you use is doing. If you're talking about the Android side, it looks like it does the chunking for you:

http://developer.android.com/intl/de/reference/android/nfc/NdefRecord.html

Note that it represents the unchunked record (and provides no access to the MB/ME flags referenced in the standard).  This is exactly what you would like a higher-level API to do for you.

That took even less time to find.

Send? Just what do you think NFC is, exactly? It sounds like you think it's an alternative to WiFi or Bluetooth. That's not exactly true, or only approximately true, depending on how you want to look at it.

While in theory you could use it to communicate between two devices, the short range involved, and the low speed, make it less than attractive for this. If you Bluetooth or WiFi available, those would be much more natural. So you may want to rethink whether this is the right tool for your job.

Probably as a result, the activity I'm aware of is more around RFID tags and various active readers. Probably there are people doing it, my point is just that it doesn't seem to be terribly mainstream, and you may have trouble finding code samples.

Yes, you'll have to divide it.  The details are clearly laid out in the NDEF standard document, which should only have taken you two minutes to locate. That's how long it took me, anyway, starting from never having read any technical details on NFC. Really, I just entered NFC Tag into Google, clicked on Wikipedia, and clicked on this link from the Standards section there:

http://www.nfc-forum.org/specs/

See Section 2.3.3 of the NDEF spec.
