Android Question Send PDF with Whatsapp

[menneaduplo]

Hi All,
I need to send a PDF via whatsapp.
The code below has stopped working. I don't know exactly when.
I don't think it depends on B4a 11.50. Maybe Whatsapp has changed something?
Can anyone help me.

    File.Copy(File.DirDefaultExternal,"document.pdf",Starter.Provider.SharedFolder,"document.pdf")
    Dim sendIntent As Intent
    sendIntent.Initialize(sendIntent.ACTION_MAIN,"")
    sendIntent.Action=sendIntent.ACTION_SEND
    sendIntent.SetPackage("com.whatsapp")
    sendIntent.SetComponent("android/com.android.internal.app.ResolverActivity")
    
    sendIntent.SetComponent("com.whatsapp/.ContactPicker")
    sendIntent.putExtra("jid", PhoneNumber & "@s.whatsapp.net")
    
    sendIntent.PutExtra("android.intent.extra.STREAM", Starter.Provider.GetFileUri("documento.pdf"))
    sendIntent.PutExtra("android.intent.extra.TEXT","Si allega documento :")
    sendIntent.SetType("application/pdf")
    StartActivity(sendIntent)

There is the following exception
Thanks in advance.

StartActivity(sendIntent)

I use this code:

Dim i As Intent
i.Initialize(i.ACTION_SEND, "")
i.PutExtra("android.intent.extra.STREAM", Starter.Provider.GetFileUri("file.pdf"))
i.SetType("text/plain") 'it is not related to the file itself.
StartActivity(i)

Also note to use Fileprovider in your app. Above code is based on fileprovider.

[class] FileProvider - share files

Edit: FileProvider is included as an internal library now. After investigating several issues with the current FileProvider code that you can find in the forum, I decided to make some improvements and implement it in a class. Starting from Android 7 (API 24) you cannot directly share file uris...

Thanks for the reply but I also need to set the number to send the PDF to.
