showWebPopup

I cant seem to get showWebPopUp to work. Im testing on a droid incredible. my code is below…

local function webListener( event )  
 local shouldLoad = true  
  
 local url = event.url  
 if 1 == string.find( url, "corona:close" ) then  
 -- Close the web popup  
 shouldLoad = false  
 isWebPopup = false -- show Web object is gone  
 end  
  
 return shouldLoad  
end  
  
  
local function launchTwitter( event )  
 if(event.phase == "began")then  
  
 media.playEventSound(shootSoundID) -- i play this sound to be sure that this function is called  
  
 local options = { hasBackground=true, urlRequest=webListener }  
  
  
  
 native.showWebPopup(0, 0, \_screenWidth, \_screenHeight, "http://www.twitter.com", options )  
  
 end  
end  
  

Am i doing something wrong? I have the internet permission set.
Can i send an intent so that a web browser launches with the specified url? [import]uid: 27671 topic_id: 9106 reply_id: 309106[/import]
