Awesome, i've been working on something similar, maybe i will post it later on, basically the library i'm working on you can search for a video title name or artis, and it will return a list of videos which you can extract the video Id number from, using your library i can now convert this videos to mp3, great work.

Thanks,
Walter

I just tested your library and i'm getting the following error, any idea as to why this is, i tried it with your example and get the same error. Am I missing something?

Yes I do, but you didn't specify in your first post all this libraries were needed, i was under the impression that when you compile a module into a library any libraries you use also get compiled along with the library you are creating.
Am I wrong?

Ok, i have included all the libraries you mentioned in post #5, but i still get the same error!
It's a shame because i'm done writing my library and i was hoping to start making a small app where you can search for any song title using the youtube api, and using your library to convert the videos to mp3.

Let me know if you figure out why i'm seeing this issue!

Thanks,
Walter

I'm running your example, I tried running it in debug mode, and release mode as well, both modes give me the same issue.
don't worry about my movie, the link gets corrupted when you paste it inside the <quote></quote>.

Walter

Yes i have, i tried on my samsung Tab running version 4.4.2 and my LG G3 running version 5.0.1. i get same error on both devices.

The issue is obviously at this line

"main_activity_create (B4A line: 32)"
B4X: 
mp3.Initialize("https://www.youtube.com/watch?v=i62Zjga8JOM", True, "YouTube", Me, "check_short")

Ok, the problem is this line 48, If i comment this line everything works fine.

B4X: 
job1.GetRequest.SetContentEncoding("text/plain")

this is the error i get and the application stops exactly at line 48 of your class.

B4X: 
** Activity (main) Create, isFirst = true **

One more issue i just noticed, now that everything is working fine, i noticed that even though the response from the server says that the mp3 file was successfully downloaded, for some reason when i go to the Youtube_Mp3 folder the mp3 file does not appear to be inside that folder, it might me an issue with Lollipop version, i do not see this issue on my samsung galaxy tab 7, any ideas what could be going on?

Walter

Ok, i made some modifications to your class, i found the following issues:

#1 You need to create the directory where the mp3 will be downloaded to, this was the reason why your example would fail in my LG-G3 running lollipop version.
I added the following code for that:
B4X: 
    If File.IsDirectory(File.DirRootExternal, Folder) = False Then
    Log("creating directory: " & Folder)
        File.MakeDir(File.DirRootExternal, Folder)
    Else
    Log("Folder already exists!")
    End If
#2 You need to register the DownloadManager, otherwise the DownloadComplete Sub will never be raised.
I added the following code for that
B4X: 
DownloadManager1.RegisterReceiver("DownloadManager1")
#3 You are using a Utils module, which was never initialized.
I added the following code for that
B4X: 
    If Utils.IsInitialized=False Then
        Utils.Initialize(DownloadManager1)
    End If
#4 I noticed that when you are using a secured network, the requests don't work, and I also unencoded the URL retrieved.
using the following code:
B4X: 
 Dim su As StringUtils
 DOWNLOAD_ADDRESS =valore.link.Replace("http", "https")
 DOWNLOAD_ADDRESS = su.DecodeUrl(DOWNLOAD_ADDRESS, "UTF-8")
#5 and lastly, I moved this code:
B4X: 
CallSub2(MN,EN,valore)
to the Private Sub DownloadManager1_DownloadComplete(DownloadId1 As Long) sub
you had it at the JobDone sub which was not realistic, as the true completion of the download is at the DownloadManager1_Downloadcomplete sub.

i'm attaching the revised version of your class, you should recompile with a new version and repost it.

Cheers,
Walter
