WHY BADA?y USER INTERACTIVE
Samsung bada platform provides aneasy, simple,
and intuitive UI without compromisingefficiency.
To enhancecreativity and userinteractivity, itprovides flash
control, web control, motion
sensing, fine-tuned vibrationcontrol, and face
detection. Also, it supportssensor-based, context-
aware applications.Byusingvarioussensorssuchas accelerometers,
tilt, weather, proximity, and
activitysensors, application developerscaneasily
implement context-awareinteractive applications.

existsin one of four possiblestates:Initializing, Running,
Terminating, or
Terminated.

UI FRAMEWORKy Frameworks enableyour app to take
advantage ofready-made behaviour.
y Badas languageis C++, badas frameworks
use C++ inheritance to share behaviourbetween the frameworks and
your app .
y The bada C++ frameworksuse derivation and
virtual functions to shareresponsibilities
between the frameworkitself, and apps thatuse the
frameworks.

BADA ECOSYSTEMy Usersexpect to be able to find and download
thesoftware
they want using their device when theyre on the move.Usersshould
beserved following a wish and usenotion.Whenusers wish to satisfy a
current need theyshould beable to get and
usecorrespondinginformation orservices
as fast and simple as possible. They want the purchasingand
installation process to besimple, which is where acentral onestop
shop such as the SamsungApps storecomesin. Developers distribute
their applicationsviaSamsungApps, onecentrallocation from which
users ofbada devicescan purchase and download apps and make
in-app purchases. Onesideeffect of this approach is
thatthenetwork operatorno longer plays the gatekeeperroleto their
devices, theusercan freely decide which apps toinstall.
-
8/7/2019 Bad A
27/42
y A further positivesideeffect resulting from the
appstoreinitiativesis that costs all of a sudden becomemuch more
transparent. Network operatorsrecognised this trend and cameup with
contractbundles with flat data rates orvolume packagesinorder to
encourage the download of apps from stores.In the past,
incomprehensible and non-transparentcost models discouraged users
from using mobileservices or downloading mobile apps because
theyfeared exaggerated costs. With new all-inclusive
models, downloading apps and invoking mobileservices has become
a lot moreuser friendly and thusaccepted.From this, weconclude that
the future ofmobile apps ahead ofusshould be quite promising.
