Android Question whatsapp - attach a file to message

Zeev Goldstein · Mar 17, 2023

hi,

I'm using this code to send WhatsApp messages

B4X:

        Intent1.Initialize(Intent1.ACTION_VIEW, $"https://api.whatsapp.com/send?phone=${EditTextNumber.Text}&text=${EditTextMessange.Text}"$)
        Intent1.SetComponent("android/com.android.internal.app.ResolverActivity")
        StartActivity(Intent1)

how can i add a file?

and - how do i send using WhatsApp bossiness instead ?

thanks

hi

i tried, something went wrong
i made some lite changes as i got errors on shared etc (maybe declarations)
so i put it in a sub

B4X:

Sub Send_WhatsAPP_Attachment(Phone As String, Msg As String, FileName As String)
    Dim sendIntent As Intent

    Try
     
        If File.Exists(File.DirInternal,FileName) Then
            File.Delete(File.DirInternal,FileName)
        End If

        File.Copy(File.DirAssets,FileName, File.DirInternal, FileName)
 
        sendIntent.Initialize(sendIntent.ACTION_MAIN,"")
        sendIntent.PutExtra("jid",Phone & "@s.whatsapp.net")
        sendIntent.Action=sendIntent.ACTION_SEND
        sendIntent.SetPackage("com.whatsapp")
        sendIntent.SetComponent("android/com.android.internal.app.ResolverActivity")
        sendIntent.PutExtra("android.intent.extra.TEXT",Msg)
        sendIntent.PutExtra("android.intent.extra.STREAM", File.Combine(File.DirInternal,FileName))
        sendIntent.SetType("application/pdf")

        StartActivity(sendIntent)

    Catch

        Log(LastException.message)

    End Try
 
End Sub

now no errors but when i try to send i get a message that it cannot share

i put a pdf file in assets so i cant try
but what if i want to use another type like jpg ?

and last thing: what should i do if i want to use whatsapp for bussiness too?
what should i change?

any ideas?
hat went wrong?

thanks

Hi, I use it with PDF and it works, but I saw that you changed the code, you removed the comments.

As for Wu, I don't have the business version, I can't test.

B4X:

Dim FileName As String = "documento.pdf"  'change it
Sub Send_WhatsAPP_Attachment(Phone As String, Msg As String, FileName As String)
    Dim sendIntent As Intent

    Try
     
        If File.Exists(File.DirInternal,FileName) Then
            File.Delete(File.DirInternal,FileName)
        End If

        File.Copy(File.DirAssets,FileName, File.DirInternal, FileName)
 
        sendIntent.Initialize(sendIntent.ACTION_MAIN,"")
      '''  sendIntent.PutExtra("jid",Phone & "@s.whatsapp.net")  >>>> REMOVE
        sendIntent.Action=sendIntent.ACTION_SEND
        sendIntent.SetPackage("com.whatsapp")
        sendIntent.SetComponent("android/com.android.internal.app.ResolverActivity")
        sendIntent.PutExtra("android.intent.extra.TEXT",Msg)
        sendIntent.PutExtra("android.intent.extra.STREAM", File.Combine(File.DirInternal,FileName))
        sendIntent.SetType("application/pdf")

        StartActivity(sendIntent)

    Catch

        Log(LastException.message)

    End Try
 
End Sub
