New Features

The following Mobile Web Device APIs have been added in this release to allow a richer variety of features to be implemented in mobile Web applications:

Web Device API
The following Mobile Web Device APIs have been added in this release to allow a richer variety of features to be implemented in mobile Web applications:
- Account API (tizen.account)
  - Manages accounts within the device. For example, applications can use this API to create an account or change account information.
- Archive API (tizen.archive)
  - Creates an archive file and operates on it. For example, applications can use this API to extract files from an archive or add a file to an archive.
- Badge API (tizen.badge)
  - Overlays an image with the number of unread notifications for an application on the application’s Home screen icon. The image is known as a badge.
- Bluetooth API
  - Manages Bluetooth connections. An application must now request permission from the user to use Bluetooth. Previously, you were able to enable Bluetooth without user consent, but that API is to be deprecated soon. To request permission, you must now launch the Bluetooth settings option from within your application so that the user can choose to enable Bluetooth. Similarly, applications must no longer change a device’s Bluetooth visibility, as this API is also to be deprecated.
- Exif API (tizen.exif)
  - Manipulates exchangeable image file format (Exif) metadata.
- FM Radio API (tizen.fmradio)
  - Manages FM radio operations, such as switching the FM radio on or off, scanning frequencies, and tuning up or down.
- Human Activity Monitor API (tizen.humanactivitymonitor)
  - Provides support for pedometers, heart rate monitors (HRMs), and GPS tracking features to determine the device’s geographical location and changes, such as velocity changes. It also supports the detection of “wrist-up” motions. For example, if a smartwatch user rotates their wrist to look at their watch screen, the application can detect this and present content on the screen.
  - Only HRMs are supported on the Tizen 2.3 mobile and wearable Emulator.
- MediaKey API (tizen.mediakey)
  - Provides methods to handle multimedia keys, such as the volume control or pause buttons on a Bluetooth headset connected to the Tizen device.
- Sensor API (tizen.sensorservice)
  - Supports light, magnetic, pressure, proximity, and ultraviolet sensors.
  - All sensor types are supported on the Tizen 2.3 mobile and wearable Emulator through the Event Injectors.
- Sound API (tizen.sound)
  - Controls the sound volume level for various sound types, such as system sounds, media playback audio, notifications, and alarms. It also gets information about the sound mode of the device, such as whether it is set to the mute or vibrate mode.
The following features have been added to the existing Mobile Web Device APIs in this release:
- Calendar API
  - The feature to use calendars from multiple accounts has been added. This is useful because you can create, add, or remove calendars from different accounts by using their account ID.
- CallHistory API
  - The device’s local phone number (calling party) attribute can now be added to the call history information. This is particularly useful in dual SIM devices.
- Contact API
  - The feature to use contacts from multiple accounts has been added. This is useful because you can create, add, or remove contacts from different accounts by using their account ID.
  - The following attributes (among others) have been added for individual contacts: relationship, messenger address, contact message alert setting, and contact vibration pattern URL.
- Content API
  - The 'isFavorite' attribute has been added to the Content interface to mark favorite content.
  - The playlist feature has been added so that you can add, remove, and update your favorite media content.

  - The feature to retrieve unread push notifications when your application is connected to a push service has been added.
- Secure Element API
  - The feature to get received data from the application select command (getSelectResponse()) has been added.
- System Information API
  - The new profile name enum values (MOBILE, WEARABLE) have been added to be used in the application manifest (config.xml) to indicate which device types your application can support. Note that the previous enum values (MOBILE_FULL and MOBILE_WEB in SystemInfoProfile) have been deprecated.
  - The getCapabilities() method has been replaced with getCapability() and must be used to retrieve the device capabilities.
  - The feature to get information about multiple system properties, such as dual SIM card capabilities, has been provided. For example, in the previous API, you were able to retrieve the information for a single SIM card only; however, now you can get an array of available SIM cards on the device.
  - The feature to get memory state information, total memory size, and available memory size has been added. You can query the total memory on the device as well as the currently available memory in bytes.
  - The DUID has been replaced with tizen ID, which is a randomly-generated value based on the model name.
  - The feature to obtain the Wi-Fi MAC address information has been added.
- TBM Surface API
  - The feature to get low-level graphic buffer which is provided by system has been added.

- The default theme file path has been changed from tizen-web-ui-fw/{version}/theme/default/theme.css to lib/tau/mobile/theme/default/tau.css.
- The date-time picker and multimedia view widgets have been deprecated. Use the HTML standard instead (input, video, and audio elements).
- The gallery3D, split view, and virtual grid widgets have been deprecated.

Fixed Bugs

Web UI Framework (TAU)
- The issue of the ‘refresh’ method of the listview winset not working properly has been fixed.
- The broken button style has been fixed.

Native Framework

The Tizen platform provides a new API for native applications in Tizen 2.3, replacing the previous Tizen 2.2.1 Native API. The primary development language for native applications has changed from C++ to C. However, the C++ standard library has been provided as an open source library, so C++ can still be used to create the application logic that does not use any Tizen platform features. This big change has been made for the following reasons:

The Tizen native framework currently only supports the mobile profile. However, in the near future, multiple other device profiles, such as wearable and TV will be supported. A new Native API is required to ensure that the native framework is lightweight and fast to run well on both low- and high-end profiles and devices.
With the new native framework, minimal porting effort is required to run native applications on multiple Tizen device profiles.
Improved scalability, and fast, themeable, and easily customizable graphics are now possible by using the Enlightenment Foundation Libraries (EFL).
More than 10 open source libraries are now available to 3rd party applications through the native framework. This is particularly advantageous for developers who are already familiar with some of these libraries, because they can quickly add features and use previous written code in certain cases.

Note that you cannot use the new Tizen 2.3 SDK to develop native applications that have been written with the older Tizen SDKs. If you want to develop a native application written with an older Tizen SDK, rewrite your application with the new Tizen 2.3 SDK. The signature changes of Native APIs from Tizen 2.3 Beta to Tizen 2.3 release can be found from here.

Known Issues

IDE and Tools
- Because the old workspace metadata is incompatible due to the major upgrading effect, an IDE crash can occur. Create new workspace to avoid the problem.
- The Connection Explorer view sometime does not show all running Emulator information.
Web UI Builder
- The text functions (ellipsis and line-break) are sometimes displayed differently with an actual operation.
- Some TAU widgets are not included in the widget palette nor work properly.
- The selected resolution in the N-Screen View is not applied on the application.
- In some cases, the designer does not work properly if you modify the HTML code directly.
- The scroll bar is displayed in the middle of the content area in the Simulator, if the animation applies to the content.
- The animation does not work properly with N-Screen.
- The IDE creates a console window when an internal browser has been created in Windows 8.
Emulator
- On Windows®, depending on your OS theme (such as non-Aero themes and Windows XP themes), a display surface can be erased for a while if the Emulator window is obscured by another window. If you click the Emulator window, the display surface works correctly again.
- The Emulator skin cannot be drawn properly on Ubuntu™, if the graphics driver is not installed or an old version is installed. To fix this issue, upgrade the graphics driver.
- When the disk storage is full, various incorrect operations can occur.
- To use the Tizen Emulator, you need, for example, an Intel VTx supported by the CPU, and the latest vendor-provided version of the graphic card driver. Check the prerequisites for the Tizen Emulator from:
  - https://developer.tizen.org/downloads/sdk/installing-sdk/prerequisites-tizen-sdk
  - On Ubuntu, if the host machine is using Nvidia Optimus™ technology, you can set the Tizen Emulator to run with your Nvidia® graphics card through the bumblebee project: https://wiki.ubuntu.com/Bumblebee
- The browser for the map of the location tab does not support HTTPS/SSL certificate on Ubuntu.
- Sound control does not work properly in wearable settings application.
