Android Example Share a PDF with a specific WhatsApp number.

Hi everyone, i've been working with B4A since 2016 or maybe 2015 and today, after a request from a client. I needed to send a PDF to a specific number in whats app.

After two days, i finally figure it out

Im sharing this here with you all, because is this forum what keeps B4A alive.

Im using cPDF for create the PDF file.

'These are my functions that im currently using

Sub savePDF(apdf As cPDF,afile As String,acompress As Int)
    Dim folder As String
    folder=Starter.fFileProvider.SharedFolder
    apdf.saveToFile(folder,afile,acompress)
End Sub

Sub openPDF(afile As String)
    Dim in As Intent
    in.Initialize(in.ACTION_VIEW, "")
    Starter.ffileProvider.SetFileUriAsIntentData(in, afile)
    in.SetComponent("android/com.android.internal.app.ResolverActivity")
    in.SetType("application/pdf")
    StartActivity(in)
End Sub

Sub sharePDF(afile As String)
    Dim in As Intent
    ' Inicializar
    in.Initialize(in.ACTION_SEND, "")
    Starter.ffileProvider.SetFileUriAsIntentData(in, afile)
    in.SetComponent("android/com.android.internal.app.ResolverActivity")
    in.SetType("application/pdf")
    in.PutExtra("android.intent.extra.STREAM", Starter.ffileProvider.GetFileUri(afile))
    in.SetPackage("com.whatsapp")
    StartActivity(in)
End Sub

Sub sharePDFToViaWs(afile As String, toNumber As String)
    Dim in As Intent
    in.Initialize(in.ACTION_SEND,"")
    Starter.fFileProvider.SetFileUriAsIntentData(in, afile)
    in.SetType("application/pdf")
    in.SetPackage("com.whatsapp")
    in.PutExtra("android.intent.extra.STREAM", Starter.fFileProvider.GetFileUri(afile))
    in.PutExtra("jid", "57" & toNumber & "@s.whatsapp.net")
    StartActivity(in)
End Sub
