Hi

Could you share an example of a complete project because it gives me an error with

I wanted to know if I should add any other configuration

is there any way to open whatsapp with especific number?

As what I have guessed. The code you posted above is for B4i.
In B4A, you can use Intent.

B4X: 
Sub SendToWhatsapp(TextToSend As String)
    Dim Intent1 As Intent
    Intent1.Initialize(Intent1.ACTION_SEND ,"")
    Intent1.SetType("text/plain")
    Intent1.SetComponent("com.whatsapp/.ContactPicker")
    Intent1.PutExtra("android.intent.extra.TEXT", TextToSend )
    StartActivity(Intent1)
End Sub

thanks guys now the question is this.

what will happen if one user is on ios and send the url to user that is on android?
is it possible to create a universal url that will work on both platform?

EDIT: so i will explain what i mean.
the link should be shared using whatsapp and clicking on it should open the app and read the string that is shared with the url (like a id).
