Subject: Re: Local File in Browser Widget on Android - Fail

Sannyasin,

Thank you for the reply!   I have discovered that it’s not the local path the is the issue.  If I do this, I see “123” in the browser:

   put “123” into url ("file:" & specialFolderPath("documents") & "/map.html")
   set the url of widget "Browser1" to ("file:" & specialFolderPath("documents") & "/map.html")

However, the html document I am trying to load references images that were included in the app. These images are here: specialFolderPath("engine").  Note that a “there is a file” test proves the existence of the file.

So, here’s what I do, I load the html template from a custom property.  In my html document, I have this:

   historicalOverlay = new google.maps.GroundOverlay('<LOCALINCLUDEDPATH>/MapFinal.png',imageBounds);

I then insert the local path:

   replace "<LOCALINCLUDEDPATH>" with specialFolderPath("engine") in mapFile

Then I save the file to disk and load it into the browser widget.  On my mac and iOS it works famously.  On Android, I just get a broken image icon.

Do I have to alter the local image path somehow?

Again, thank you for the response and assistance!

    make sure your slashes are all correct. on iOS and desktop  are forgiving with double// in URLs; but android is not.. .this bit me many times
    
    file:/somepath/somefile.html
    
    works
    
    file://somepath/somefile.html  
    
    doesn't  
    
    So If you have path setters here and there, one needs to follow some convention, either leave folder string *always* with no closing slash and all appended url strings begin with a slash.. I started that way but this was always confusing to me because on web / means "from DOCROOT"   so slowly I am refactoring all these to
    
    function path_Assets
        return specialFolderPath("documents") & "/assets/" 
    end path_Assets
    
    then in any module we use 
    
    play sound (path_Assets() & "bells-whistles/ding.mp3")  because this is "relative" # very subjective..
    
    So what started failing on Android --  really hard to debug!
    
    where instances of 
    
    play sound (path_Assets() & "/bells-whistles/ding.mp3") 
    
    because these would work on Mac desktop and only fail on Android so you are beating your head "what is wrong."

        I?m having a problem loading a local file on Android in the Browser Widget in LC 8.1.5.  I am experiencing what is described in bug 19036.  But, bug 19036?s status is ?Resolved? in version 8.0.0.   So, is something else up?  Anyone have any insight?
