How to open app tray using app control?

Hi,

I have requirement where I have to open app tray (same which opens when you press Home button) using app control.

I tried it with app id “com.samsung.w-home” but it’s not opening app tray.

Thanks

So far I did not find any application ID to do so.

try to use following approach (equivalent in web api) to check what application is launched or terminated:
app_manager_set_app_context_event_cb

Thanks for suggestion.

I have tried “app_manager_set_app_context_event_cb” but it’s not being invoked on home button press. So can’t figure out which app is being launched on home button press.

Actually we have dropped that idea of launching app tray manually.
