Subject: Fixes Settings app crashing when NfcAdapter is null
X-Git-Url: http://git.osdn.net/view?a=commitdiff_plain;h=37efa64d63c3d24170a4deca4eb407f4517edfe1;p=android-x86%2Fpackages-apps-Settings.git

Fixes Settings app crashing when NfcAdapter is null

If a device doesn't support NFC then
android.settings.NFCSHARING_SETTINGS and
android.nfc.cardemulation.action.ACTION_CHANGE_DEFAULT intents shouldn't
do anything and gracefully exit.

Test: Manual; Emulate a non-NFC device and test with apks sending intents
