an app working like sony smart tags and...
and it can detect ANY NFC tags as functional cards.
when it's detected a certain card. it will change the settings programmed.
i solved the codes of
wifi switch on/off
auto brightness on/off
auto sync on/off
launch vpn settings
connect to a certain wifi hotspot
here is the examples.
with Card A - Company Card (used my canteen card)
wifi on, auto sync on, dim brightness, and launch the vpn,
try to connect to my personal wifi hotspot.
with Card B - Outdoor Card (used my traffic card)
wifi off, auto sync off, auto brightness on,
with Card C - Home Card
wifi on, sync on, dim brightness.
so when i go outdoor and don't need to find the widget to turn on auto brightness, just tap the traffic card. done!
but this app is too personalized, not suitable for everyone. all the tags used now is static data in the codes. :P
anyone wants to expand the app to have settings, menus, and nice UIs?
