Tizen 2.4 Release Notes

  • Release Date: October 22, 2015

The Tizen 2.4 SDK supports the development of Tizen 2.4 applications only. To develop an application based on the Tizen 2.3 platform, you must use the Tizen 2.3 SDK.

IDE and Tools

New Features

  • Web IDE and Tools
    • Rest Viewer has been added.
    • Multi Package preference panel has been added to Project Properties > Tizen SDK > Package. You must refer projects to other projects in this panel, not in the Project Reference panel. The hybrid project referencing feature is removed from the Project Reference panel.
  • Native IDE
    • New project template types (IME, widget, and watch) have been added.
    • Project migration wizard, which imports 2.3-based projects for making 2.4-based projects, has been added.
    • Resource Manager View, which places application resources to support specific device configurations, such as different screen densities and locales, has been added.
    • Select Emulator Wizard, which calls a previously run emulator automatically while ‘Run As’ is called and Emulator Manager is not running, has been added.
    • Ninja build system for enhancing the application build time has been added.
    • LLVM-3.6 and GCC-4.9 toolchains have been added.

    • The bug, where the emulator is terminated abnormally due to the misconfiguration of SOCKS (SOCKet Secure) proxy on Mac OS® X, has been fixed.

​​Known Issues

  • Install Manager and Update Manager
    • If there is a multibyte character in the installation path of the Tizen SDK, some development packages cannot find the installed SDK’s location when they are working.
    • When you install packages by using the All Packages tab in the Update Manager, the number of the progress indicator is changed only each time a package in dependency is downloaded. While downloading, the number of the progress indicator is not changed. 
  • Native IDE
    • Generating the res.xml file in Multi-Packaged projects is not available.
    • When you import some projects generated from the Tizen 2.3 Rev2 SDK, the importing can take some time.
  • Emulator
    • To use the Tizen Emulator, you must install an Intel VTx supported by the CPU, and the latest version of the graphic card driver which the vendor provides. Check the prerequisites for the Tizen Emulator from:
      • https://developer.tizen.org/downloads/sdk/installing-sdk/prerequisites-tizen-sdk
      • If the host machine is using Nvidia Optimus™ technology on either Ubuntu™ or Windows®, set the Tizen Emulator to run with your Nvidia® graphics card. In case of Ubuntu™, check the bumblebee project (https://wiki.ubuntu.com/Bumblebee). In case of Windows®, select "High Speed NVIDIA Processor" as "Preferred Graphics processor" in the Nvidia® control panel.
      • On Ubuntu™, if the graphics driver is out-of-date, your Ubuntu® desktop session can be occasionally logged out when launching the Emulator Manager. Or the Emulator skin can be drawn improperly. Check the prerequisites and upgrade the latest graphics driver.
    • On Ubuntu™ 14.04, the shortcut menu can sometimes appear transparently.
    • 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 covered with another window. If you click the Emulator window, the display surface runs correctly again.
    • On Windows®, if ‘failed to allocate memory’ error occurs while executing the Emulator, try the following:
      • Close some other programs and try to launch the Emulator again.
      • If the RAM size is set as 768 or 1024 MB for the VM in the Emulator Manager, change the RAM size to 512 MB.
      • Increase the user area of the virtual memory in the system to 3 GB by typing the bcdedit /set increaseuserva 3072 command on the console with administrator rights (Windows® 7 only) and reboot.
    • If you use a MacBook Pro which has both Intel HD and NVidia GPUs, when you execute the Emulator with the OpenGL ES ver. v1.1 & v2.0 option, the Emulator can be unexpectedly terminated. Use the OpenGL ES ver. v2.0 & v3.0 option.
  • SDB
    • To use the SDB bash completion feature, you must type the source .sdb-complete.bash command on the bash shell. The feature runs manually from the Tizen 2.4 due to the Installer and Update Manager issue.
