Hello,

I am working on localizing my channel and I wanted to use the

GetLocalizedAsset

function as this is documented as the proper way to pull localized assets.

I am using an

roListScreen

and populating it with:

    contentList = [
        {
            Title: tr("Live Stream"),
            ID: "1",
            'SDSmallIconUrl: "pkg://locale/default/images/live_stream_small.png",
            'HDSmallIconUrl: "pkg://locale/default/images/live_stream_small.png",
            'HDBackgroundImageUrl: "pkg://locale/default/images/live_stream_poster_art_hd.png",
            'SDBackgroundImageUrl: "pkg://locale/default/images/live_stream_poster_art_sd.png",
            HDBackgroundImageUrl: GetLocalizedAsset("images", "live_stream_poster_art_hd.png"),
            SDBackgroundImageUrl: GetLocalizedAsset("images", "live_stream_poster_art_sd.png"),
            ShortDescriptionLine1: tr("Live Stream"),
            ShortDescriptionLine2: tr("Broadcasting around the world"),
            CallBack: LiveStream
        },
        {
            Title: tr("Alternate Language Live Stream"),
            ID: "2",
            'SDSmallIconUrl: "pkg://locale/default/images/alt_stream_small.png",
            'HDSmallIconUrl: "pkg://locale/default/images/alt_stream_small.png",
            'HDBackgroundImageUrl: "pkg://locale/default/images/alt_stream_poster_art_hd.png",
            'SDBackgroundImageUrl: "pkg://locale/default/images/alt_stream_poster_art_sd.png",
            ShortDescriptionLine1: tr("Alternate Language Live Stream"),
            ShortDescriptionLine2: tr("Alternate language of our live stream"),
            CallBack: AltLangStream
        },
        {
            Title: tr("About Us"),
            ID: "3",
            'SDSmallIconUrl: "pkg://locale/default/images/about_small.png",
            'HDSmallIconUrl: "pkg://locale/default/images/about_small.png",
            'HDBackgroundImageUrl: "pkg://locale/default/images/about_us_poster_art_hd.jpg",
            'SDBackgroundImageUrl: "pkg://locale/default/images/about_us_poster_art_sd.png",
            ShortDescriptionLine1: tr("About Us"),
            ShortDescriptionLine2: tr("Some basic information about us"),
            CallBack: AboutUs
        }
    ]

As you can see I just commented out the code that works (absolute path) but when I use the

GetLocalizedAsset

function I get the following error in the debug console:

Function Call Operator ( ) attempted on non-function. (runtime error &he0) in ...g:/source/mainContentList.brs(12)
012:             HDBackgroundImageUrl: GetLocalizedAsset("images", "live_stream_poster_art_hd.png"),

getlocalizedasset &h0000 <uninitialized> val:Uninitialized

line 12 is:

HDBackgroundImageUrl: GetLocalizedAsset("images", "live_stream_poster_art_hd.png"),

Am I using this wrong? Can this not be using in the main.brs? My main.brs is:

' ******************************************************************
' * This is the main function, this is the channel's starting point
' ******************************************************************
Sub Main() 
    print "Channel Initialized - ";
    ' Initialize the theme
    InitTheme()
    ' Create screen and event listener port (roMessagePort)
    screen = CreateObject("roListScreen")
    port = CreateObject("roMessagePort")
    ' Set lister port to screen
    screen.SetMessagePort(port)
    ' Set screen content title
    screen.SetHeader( tr("Welcome to the Sonlife Network") )
    ' Initialize content list (main page)
    contentListOptions = MainContentList()
    ' Assign the content list to the screen
    screen.SetContent(contentListOptions)
    ' Show the content list
    screen.show()
    ' Keep channel open and monitor event listener
    while (true)
        ' Define event
        event = wait(0, port)
        ' Check if current screen event
        if (type(event) = "roListScreenEvent")
            print "----------------------[ Main Page | roListScreenEvent ]----------------------"
            ' Check for focused item
            if (event.isListItemFocused())
                print "Calling Title for index: " ; event.GetIndex()
                ' Update breadcrumb
                screen.SetBreadcrumbText(tr("Menu"), contentListOptions[event.GetIndex()].Title)
                print "Calling Title Complete"
            else if (event.isListItemSelected())
                print "Calling Callback for index: " ; event.GetIndex() ; " - " ; contentListOptions[event.GetIndex()].Title
                ' Do callback when selected
                contentListOptions[event.GetIndex()].CallBack()
                print "Callback Complete"
            endif      
        endif ' End Check for events
    end while ' End Keep channel open
End Sub

' Checks if display is HD
Function isHD() As Boolean
    di = CreateObject("roDeviceInfo")
    if di.GetDisplayType() = "HDTV"
        print "HDTV"
        return true
    else
        print "Regular TV"
        return false
    end if
End Function

' Gets the current locale
Function getLocale() As String
    di = CreateObject("roDeviceInfo")
    return di.GetCurrentLocale()
End Function

MainContentList()

returns the code I pasted above.

Any help/insight on why this is throwing an error would be much appreciated.

My file structure is:

locale
   |--- default
        |--- images
   |--- en_US
        |--- images
   |--- es_ES
        |--- images

Thanks

GetLocalizedAsset() is a method on the roLocalization component. You need to create that component to use it, per the example here: http://sdkdocs.roku.com/pages/viewpage. ... Id=3114130

Thanks!

I used this post on the dev blog but there was no reference for it.

Now I have an issue where I have to initiate

loc = CreateObject("roLocalization")

in all .brs files that use it... Seems like this would be better as a global. Are there any tricks I am missing?

Yes, that blog post is wrong in saying

"Localizing Your Roku Channels" wrote:
... So you would call GetLocalizedAsset as follows:

path_to_image = GetLocalizedAsset(“images”, “playbutton.png”)

Apparently Mr.Burdick could not be bothered trying the code before posting it... yuck! And RokuCo could not get their act together for almost 2 years and properly add section on localization in the SDK documentation.

"There is no different .brs files... only Zuul" 😛 - just saying, in case you think separating in different files creates different namespaces/packages; all functions from any file are global scope. But the spirit of your question is probably that you want to use get-ass-etc in multiple functions. Here is a trick, define it as your own (global) function in one of the files and in it use a singleton:

function getLocalizedAsset(dirName as String, fileName as String) as String:
    loca = m.roLocalization
    if loca = invalid:
        loca = createObject("roLocalization")
        m.roLocalization = loca
    end if
    return loca.getLocalizedAsset(dirName, fileName)
end function

Works perfectly! Thanks a lot
