B4A Library DownloadProgressView V1.0.1 (uses the Android Downloadmanager to download)

This is a wrapper for this project.

An android view showing a download progressBar, total size, downloadedSize, percentage downloaded and a cancel button of the android DownloadManager with just few lines of code. Just like Google Play downloading...

Downloads made by this library uses the Android Downloadmanager (Systemservice).
But additional to the Notificationprogress you got you also can show the progress inside own app.

If you want to donate for my work building the wrapper you can do it here:

Known issues:
As of yet it downloads all files to the internal FILES dir (ASSETS). On my device it works but i dont know about other devices. Working on it to make it changeable. Hopefully this weekend i will release a update.

Please note the changes in the manifest in example.

Dont forget to add

AddPermission(android.permission.INTERNET) ' Allows applications to open network sockets.
AddPermission(android.permission.WRITE_EXTERNAL_STORAGE) ' Allows an application to write to external storage.

to your manifest

Ooh very nice @DonManfred.
I'm sure that this library will come in handy, especially when the end user is downloading a large file

Hi, @DonManfred This library is good, but can I just get the Progress from it? I use a custom control to display download % and this lib could save me a lot of headaches!

Thanks

Aidy

 

[DonManfred]

but can I just get the Progress from it?

Yes. That´s what the library is made for.

You can for sure start multiple downloads... They all will be put into a queue for the android downloadmanager.

 

[aidymp]

Yes. That´s what the library is made for.

Sorry maybe my questions was unclear, Where is the Download progress value? as in a value I can use to display the progress in my own controls?

Thanks

Aidy

 

[DonManfred]

Where is the Download progress value?

Is is displayed in the View you can add with the Designer/by code...

 

[Rantor777]

DoEvents
End If

See new version V1.0.1 and also updated example in post #1

Sub DownloadProgress_DownloadProgress(downloadURL As String, bytes_downloaded As Long, bytes_total As Long, download_percentage As Long)
    event_count = event_count +1
    Log($"DLProgress_DownloadProgress(${event_count}: ${downloadURL},${bytes_downloaded},${bytes_total},${download_percentage})"$)
   
End Sub

But in my tries total was always -1 :-/

Hallo,
wie lässt sich die Schriftfarbe ändern?
habe es schon mit

download.TotalSizeColor = Colors.White
download.DownloadedSizeColor = Colors.White

Probiert das funktioniert aber nicht

 

[DonManfred]

Even if you know i´m a german; this is the english part of the forum. Please write ONLY english here as it will irritate all others which maybe don´t know the german language... Better ask in english or create a thread in the german forum...

Anyway:
See updated Example and docs and new lib V1.0.2 in post #1

 

[arnold steger]

this lib work whit B4A 4.30 ?
when tested crash at line
download.Initialize("DownloadProgress")

 

[DonManfred]

It crashes without any error in the logs???

 

[arnold steger]

No error. I have testet step at step in debug mode for find the line

 

[DonManfred]

Enable the unfiltered log. There MUST be somewhat to see in the log

1. enable unfiltered log
2. clear log
3. run app and do all you need to crash the app
4. copy all from the log to a file

Maybe better running in release mode

 

[arnold steger]
