This document covers how to set and test prelaunching.
Samsung TV supports “Prelaunching” for applications. “Prelaunching” allows several applications to load beforehand in background when Samsung TV turns on.
When user runs application to be prelaunched, application launches immediately without loading time. Therefore, it minimizes loading time of application.
Default value for “Prelaunching” depends on the year of TV model.
Depending on the model of Samsung TV, “Prelaunching” can be supported or not.
|Samsung TV 2016 onwards||All of higher 7000 model|
|Samsung TV 2015||All of higher 9000 model
some of Under 9000 model
|Samsung TV SDK||X|
You don’t have to turn on “Prelaunching” because default value is true. The application should be on the front of “Launcher”.
The following steps are how to place the application on “Launcher”.
After placing the application, click “Enter” button.
After turning off and on TV again, test “Prelaunching”.
If you want to test prelaunch on 2015 TV, follow the below steps.
You should to add meta data on “config.xml” because default value is false.
```xml <tizen:metadata key='http://samsung.com/tv/metadata/prelaunch.support' value='true'></tizen:metadata> ```
Only few applications are prelaunched which are run recently. So the application must run once before testing.
When TV is on again , you can see the last executed application in “Launcher” area.
