Android Question Intent Based Facebook Share

[sktanmoy]

Hi Guys,
I'm trying to share text on Facebook from the app. I was trying to use the code below but not working

Dim inten As Intent
inten.Initialize(inten.ACTION_SEND,"")
inten.PutExtra("android.intent.extra.TEXT", txtAsk.Text)
inten.SetComponent("com.facebook.katana/com.facebook.katana.stream.publish")

Try
    StartActivity(inten)
Catch
    Msgbox("It seems you don't have Facebook installed", "Error")
End Try

I was trying to follow this but failed. Can you please suggest?

What happens when it doesn't work?

Where does this component come from: om.facebook.katana/com.facebook.katana.stream.publish ?
