42. JBからのAndroid Beamのupdate
Android Beamに関する機能追加あり
Android Beam now supports large payload transfers over Bluetooth.
When you define the data to transfer with either the new setBeamPushUris() method or
the new callback interface NfcAdapter.CreateBeamUrisCallback, Android hands off
the data transfer to Bluetooth or another alternate transport to achieve faster transfer
speeds. This is especially useful for large payloads such as image and
audio files and requires no visible pairing between the devices. No additional work
is required by your app to take advantage of transfers over Bluetooth.
The setBeamPushUris() method takes an array of Uri objects that specify the data you
want to transfer from your app. Alternatively, you can implement the
NfcAdapter.CreateBeamUrisCallback interface, which you can specify for your
activity by calling setBeamPushUrisCallback().
