Extension to download file(s) to ASD (app-specific directory) without WRITE permission

Here is an extension to download any file (jpg, png, txt, apk, zip, mp3, …) to the ASD (app-specific directory) without WRITE_EXTERNAL_STORAGE permission.

Version 1 (Dec 13, 2020):
de.bodymindpowerDownloadToASD.aix (removed)
Version 2 (July 16, 2021):
DownloadToASD.aix (7.5 KB)

Version 3 (Aug 24, 2021):
Here is a special version of the extension, that does not show a notification while / after downloading.
DownloadToASD_notifHidden2.aix (7.6 KB)
Note: Use this version of the extension only if you don’t want a notification while / after downloading.

At the latest when Kodular targets API 30 (Android 11, Aug 2021), the ASD will be of outstanding importance. With this extension you can download files into this directory or subdirectories in it. With API 30 (→ targetSdkVersion=30), Google no longer allows (unrestricted) access to external storage - outside the ASD (→ Scoped Storage). See also here: Some basics on Android storage system

Kodular now uses the AndroidX libs (like AI2 is already did).

So it will soon be necessary to adjust to this and make appropriate changes and adjustments in the projects in good time.

Version 4 (April 11, 2022), EDIT: bug fix - April 19, 2022:
de.bodymindpower.downloadToAsd.aix (16.6 KB)
Added: (1) Progess event (feature), (2) .Exists (3) .Delete

A progress feature has been added. The progress can now be displayed in bytes / MB and as a percentage during the download. Thanks to @KUMARASWAMY_B.G for helping!

(Created using Rush - thank you again for this great tool @Shreyash)

Note: The DownloadProgress event doesn’t seem to complete, but it does (it just doesn’t show up in time). Therefore, you should also use the DownloadCompleted event so that 100% is displayed at the end. → See my example blocks below.

Nice Extension!
Would be better if we can avoid Download manader noptification when download finish (need option “Show Notification” like with Download component).
I uncheck Visible but do not change nothing.

This will work for pdf ?

@bodymindpower Can you also add events for progress changes, Download Failed, Already Downloaded, etc…
Thanks for such a great extension…

More features may be added later when there is time.


Could you please clarify if my understanding is correct?
we can use this extension for now, and it will not work once Kodular moves to AndroidX libs in another ~6 months time?

No I think this extension is working well in app Inventor so there is no problem with kodular even if their Update

correct, later you will have to use the App Inventor version, which already uses AndroidX

My app… downloads a zip file that is extracted so the app uses the extracted files …

With android 11 this operation fails

What shall I do Now?

Works fine on Android 11 (Pixel 2XL):


Can you please tell me what URL it will generate means file path

For ex = I want to access my file in web viewer so I need this type of URL : file:///storage…

Tried many things nothing worked! :frowning_face:

If any user use file manager it can find this file or not???

you can find it in Android 10 or below
starting from Android 11 in a file manager the directory /Android/data will be displayed as “no data available”
