Android Question Send mp3 to Whatsapp out of B4A Program

[h725]

Hello community,

1. I have a song in the files manager called "song.mp3".

2. I have a simple routine, playing an mp3:

Sub btnplaysong_click

        mp.Load(File.DirAssets, song.mp3)
        mp.Play
        
End Sub

I would like to implement the following function: If I use
the method "Sub btnplaysong_longclick" the mp3 from
the files manager should be handed over to whatsapp.
It would also be possible to open the "share with" dialog
in Android (I do not know the professionell designation):

Does anybody has an idea?

Kind regards
h725

With intent, the forum has examples.

see this:

[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...

Thank you for the fast response.
I tried this and it working fine:

Sub btnplaysong_longclick
    File.Copy(File.DirAssets, "song.mp3", Provider.SharedFolder, "song.mp3")

    Dim in As Intent
    in.Initialize(in.ACTION_SEND, "")
    in.SetPackage("com.whatsapp")
    in.setType("audio/3gp|audio/AMR|audio/mp3")
    in.PutExtra("android.intent.extra.STREAM", Provider.GetFileUri(FileToSend))
    in.Flags = 1 'FLAG_GRANT_READ_URI_PERMISSION   
    StartActivity(in)   
End Sub

Is it possible to change the name of the mp3file which shows up in the whatsapp-chat?

Thank you

yes here you can change it:

 File.Copy(File.DirAssets, "song.mp3", Provider.SharedFolder, "NEWFILENAME.mp3")

when you copy the file you can give it a new name

I found that whatsapp changed the audio file name automatically. If you were to comment out the line SetPackage and select email for example, you will notice that the attached file name will be song.mp3 and not whatever whatsapp has changed it to. Yes I know it's a pain.

I once read somewhere on the net that if one of the track tags (metadata) is present (in this case with the file name) then whatsapp will display whatever is in that tag (don't ask me which tag (metadata)). I came across this issue before, but luckily I didn't need to fix the name change issue so I just ignored it as my client didn't need the file name name to be correct, just the working audio files.

Anyway, II read it was because one of the audio file properties is blank.


Enjoy...
