Web Application Extension Libraries Q&A
The following questions are related to implementing additional features with the available extension libraries.
Extension libraries contain additional features which are supported by Samsung Smart TVs. You can use them to further enhance your application.
The available extension libraries include WebAssembly, Smart View SDK, Native Client (NaCl), CAPH, and TOAST. Samsung Hospitality Display devices, however, support only WebAssembly.
The Smart View SDK allows you to integrate Android™ devices, iOS devices, and Web browsers with Samsung TV applications. For more information, see Smart View SDK.
Smart View-enabled applications are registered in the Samsung Apps TV Seller Office separately from other Samsung TV applications. For more information, see Entering Application Information.
#smart view sdk #registration #publication #seller office
The Smart View SDK does not support smart watch applications.
However, you can use the Websocket API to implement communication between various Tizen devices, such as Samsung Smart TVs and Samsung Gear smart watches.
#smart view sdk #smart watch #samsung gear #websocket
To restore a hidden application to the foreground using the Smart View SDK, use the
start(Result<Boolean>) method of the Application class. For more information, see the Smart View SDK API References.
#smart view sdk #restore #foreground #show
Yes, you can test your Smart View-enabled application before registering it in the Samsung Apps TV Seller Office. Implement the mobile application to launch the TV application using the TV application package ID. The package ID is defined in the TV application "config.xml" file, within the
After you register the TV application in the Seller Office, in the mobile application, make sure you replace the TV application package ID with the application ID from the Seller Office. For more information, see How to manage multi app IDs.

Check that the TV has not prevented your mobile device from connecting:
- On the TV, open the mobile device manager:
- For 2016 and later models, select "Menu > Network > Expert Settings > Mobile Device Manager > Mobile Device List"
- For 2015 models, select "Menu > Network > Multimedia Device Manager"
- If your mobile device appears on the device list, make sure its switch is set to "Allow".

SSDP is supported on 2012 to 2014 TV models. On 2015 and later models, use the Smart View SDK.
#smart view sdk #ssdp #device discovery
Yes. To play multichannel streams with the NaCl Player, define the
ChannelLayout property value in the
AudioElementaryStream object. You can select from various multichannel layout values, such as
#native client #nacl player #elementary stream #multichannel audio #channel layout
You can try to export and reimport the project to the Tizen Studio:
- In the Tizen Studio, build and export your NaCl project to a ".wgt" package.
- Import the ".wgt" package as a Tizen project:
- Since importing a project does not allow you to change the project name, rename the original project.
- In the Tizen Studio menu, select "File > Import > Tizen > Tizen project".
- Select "Select archive file" and navigate to the ".wgt" package.
- Select the target TV platform, and click "Finish".
- Launch the application on the TV from the new project.

Because a NaCl application is run in a sandbox environment, it can only access files that are within its own directory. NaCl applications cannot access the system certificates directory on the TV.
If you want to use CA certificates in a NaCl application, you must place the certificates in the application directory.
#native client #nacl #ca certificate #error
To improve your application UI, you can take advantage of CAPH 3.0, a Web UI framework, based on HTML5, that is optimized for Samsung TVs.
#user interface #ui #caph
Although the CAPH Web UI framework is based on HTML5, it is only guaranteed to work with Samsung Smart TVs. For more information, see CAPH 3.0.
It is not possible to create scrollable items directly using the CAPH library. However, since you can control CAPH UI elements using HTML and CSS, you can manually add the scrollable functionality with CSS. For more information, see CSS overflow property.
#caph #scrollable #css
To make sure the scrollable list moves to show the focused item, you can trigger the "reload" event, which updates all item views.
You can also use the
select() method instead of the
focus() method, which selects the item in addition to moving focus to it.
#caph #focus #scrollable #angularjs
The icons defined in the "config.xml" file for a TOAST application have the following size requirements:
