What is bada?

bada, (bɑdɑ, the Korean word for “ocean”,) is a new smartphone platform that allows developers to create feature-rich applications

that elevate the user experience in mobile spaces.

User-interactive

Samsung bada includes a new UI framework that supports the next generation Samsung touch UI. The main UI delivers simplicity

and ease, without decreasing usage efficiency. The UI framework introduces an open-ended evolutionary innovation from the

current touch UI to leverage better user experiences.

Some additional UI tools include the ability to embed the Adobe® Flash® Player and the WebKit Internet browser directly into

native bada applications, allowing seamless integration of premiere UI technologies. Also, the bada map control is easily

embedded in your applications to deliver interactive mapping and routing with POI features for your users.

The bada platform provides user interaction modalities including motion sensing, fine-tuned vibration control, and face detection.

These interfaces open up new possibilities for greater creativity and user interactivity in developing applications. Samsung bada

also provides a mechanism to develop sensor-based, context-aware applications. With weather service and sensors such as

acceleration, magnetic, tilt, GPS, and proximity sensors, application developers can easily implement context-aware, interactive

applications.

Service-oriented

Samsung bada introduces several new service-oriented capabilities that differentiate it from conventional mobile operating

systems. These new features include social networking, content management, location-based services, and commerce services,

all supported by back-end bada servers. Developers can now create service-oriented applications without additional effort

compared to developing mobile standalone applications.

Social networking applications can manage user profiles, including buddy information for application users, and can integrate

users on most popular social networking services. Content management applications can store and search contents on devices

and servers. Location applications can use landmark stores, maps, and geo-coding services. Commerce applications can sell

products, such as game items in applications.

Open and Configurable

Samsung bada enables developers to take full advantage of mobile device capabilities to easily create compelling applications.

Applications can use device functions to make phone calls, send messages, or access the contact list, as various application

controls allow developers to create richer, more consistent applications.

Different service applications can share information such as personal profiles, social relations, schedules, and contents with

simple user confirmation, all in order to provide services with greater personal relevance and cooperative service extensions. For

example, social networking applications can share user information with commerce or location-aware applications, and share

photos from other content publishing applications.

The bada platform is kernel-configurable so that it can run either on the Linux kernel or real-time OS kernels, which makes bada

applicable to a wider range of devices than any other mobile operating system. Samsung bada uses Eclipse and a GNU tool-

chain, providing developers with a popular and extensible development environment.


What is bada?

bada Architecture

Samsung bada has a four-layer architecture: kernel, device, service, and framework layers. The kernel layer can be the Linux

kernel or a real-time OS kernel, depending on the hardware configuration. The device layer provides the core functions as a

device platform, such as system and security management, graphics and windowing system, data protocols and telephony, as

well as audio-visual and multimedia management. The service layer provides service-oriented functions that are provided by

application engines and web-service components interconnecting with bada Server. Only the framework layer can export the C++

open API. The framework consists of an application framework and functions exported by the underlying layers.
