Congratulations on your work, @MarcoRome!!

This kind of app, however, would be banned from Google Play, right?

Google will ban such apps.

Yeah, all people know this. And so I do not think anyone uses this library to an application present on Play store.

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

Post #1 Update Library 1.02 also with the contribution of walter.

Too bad Google is so strict, this is really a great addition to B4A.

There are tons of apps in the google play store like this, there are always ways of going around so they won't get banned, for one you are not hosting the content that people download, your app will simply be a tool for people to search for titles, what people do with the content is up to them.

Cheers,
Walter

UPDATE 1.02 ALSO WITH CONTRIBUTE WALTER

Hi MarcoRome, i just checked and it seems that the service you are using to convert the videos to mp3s has changed, for some reason they do not return the Json string with the title, file lenght, etc... what they do now is that the file downloads directly without returning any other information. What a Bummer, i was almost done with my App and now i have to change everything around again, I hate it when they do that, oh Well......
Just thought I'd let you know in case anyone else tries to use your library it won't work anymore.

Thanks, but what is the difference, what did you change, did you notice that the api does not return the JSON response anymore, how did you solve this?

Hi Walter you are right. Now we can only download mp3.
For the title, description, channel, etc use another service or wanting can also use the API youtube (
https://www.googleapis.com/youtube/...Key&fields=items(snippet(title))&part=snippet )

Thanks,

I see a lot of apps with download, but dont give the file, the users need open the app to listen the music, i dont know if this will cause ban

We know that play store is very limited on a few things, so it is still better to be careful before publishing something

Hello, i try the library and example but the mp3 is only 200 bytes long. I don't know where is the problem.

Thanks
