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

How could this problem be solved? Post(#18)

Update your android to V5+

@DonManfred
Sorry.
The library for less than Android 4.4 does not work?

 

[DonManfred]

Correct (regarding the use of methods from API 21)

 

[Blue.Sky]

@DonManfred tnx
Use this library to Android 5+ and lower than 5 with this code

Dim sdk As Phone
If sdk.SdkVersion >=21 Then
    downloadView.Visible = True
    downloadView.Color = Colors.RGB(136,27,154)
    downloadView.DownloadedSizeColor = Colors.White
    downloadView.TotalSizeColor = Colors.White
    downloadView.PercentageColor = Colors.White
    downloadView.ProgressBarColor = Colors.White
    downloadView.ProgressBarMode = "DST"
    downloadView.ProgressBarProgressMode = "ADD"
    downloadView.ProgressBarProgressColor = Colors.White

  
    downloadView.download(StrDownload,"sc","Description","1.mp4")
Else
    downloadView.Visible = True
    downloadView.Color = Colors.RGB(136,27,154)
    downloadView.TotalSizeColor = Colors.White
    downloadView.DownloadedSizeColor = Colors.White
    downloadView.PercentageColor = Colors.White
    downloadView.download(StrDownload,"sc","Description","1.mp4")
End if

If this works for you then you are on the right way i guess

Hi @DonManfred,
Is there a way to cancel downloading file? Thanks.

 

[DonManfred]

i think you can stop a download going over the notification!? Not sure...

 

[imgsimonebiliato]

Hello @DonManfred ,
please, how can I set destination folder like File.DirRootExternal & /testfolder"?

 

[Rusty]

does this work for prefix mode?

 

[DonManfred]

What is prefix mode?

 

[Rusty]

Astreams prefix mode. https://www.b4x.com/android/forum/threads/net-filetransfer-implement-asyncstreams-prefix-mode.30741/
Very handy transfer method.

 

[DonManfred]

This lib is just a wrapper. It calls methods to download. The rest is done by the lib and the android downloadmanager which does the download.
Don´t know how this works

 

[Rusty]

Ok, thanks. I was hoping to see the download progress of the Astreams prefix transfer.
I appreciate your rapid responses
