Android Question [solved]Open Whatsapp with a especific number

[nedium]

Hi

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

#QueriesSchemes : whatsapp (Unsupported attribute: queriesschemes)

and with

Dim app As Application
(Undeclared variable 'app' is used before any value has been assigned to it.)


I wanted to know if I should add any other configuration


in reference

is there any way to open whatsapp with especific number?

Is it possible to open Whatsapp with a especific number, I don't want to send or share anything. I just want to click on a button on my app and open Whatsapp ready to send a message or click on call I am achieving this in B4A with Dim i As Intent...

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

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
