Download Multiple Files with subfolders

@wikki74

But the COPY part does not work

This path //file/ will never exist.

@wikki74

first part (download) works now:

Does it really work? I don't think so, at least not with the compiled app (APK).

• The ASD is created automatically on Android ≥ 10.
• You cannot save / copy / download to the assets (//) and as I said this path: //files/ doesn't exist (and will never be created). So remove the .IsDevelopment and if_then_else blocks.
• And move the join block to the global strPath

Some basics on Android storage system

From an Android point of view there are an → Internal Storage and an → External Storage . 1. Internal Storage The Internal Storage can only be accessed with a rooted device. 1.1 The app package is saved in /data/data/<packageName>/ In order to be able to debug your app, AI2 saves the assets for → Companion on devices with Android ≥ 10 (API ≥ 29): /storage/emulated/0/Android/data/edu.mit.appinventor.aicompanion3/files/assets/ Android < 10 : /storage/emulated/0/Android/data/edu.mit…

Dear Anke,

it worked, but I changed it as you mentioned and Download still works.

However, path to the file looks like this:

BUT, the copy Function is still not working...

[Anke]

So the Web component also adds the ASD path (like the File component):

/storage/emulated/0/Android/data/<packageName>/files/

automatically. Try this:

Same, download works (now with the correct path) but copy does not work

[wikki74]

I think I know whats wrong:

fileName is the complete path , eg --> /storage/emulated/0/Android/data//files/files/file.pdf

so this:

Would lead to the following path:

/storage/emulated/0/Android/data//files/files/storage/emulated/0/Android/data//files/files/file.pdf

Am I right?

So what would be the correct blocks?

[Anke]

@wikki74

but copy does not work

Yes, the path is correct. But did you get an error message?

What do you get from the .Copied event?

[Anke]

@wikki74

Would lead to the following path:

/storage/emulated/0/Android/data//files/files/storage/emulated/0/Android/data//files/files/file.pdf

Am I right?

No, the block / path is correct and should be:

/storage/emulated/0/Android/data/<packageName>/files/files/file.pdf

[wikki74]

It looks like the variable "fileName" is not the correct value. It contains the entire path to the file instead of just the filename.

Yes thats right!!

But how do I get only the filename and not the path?

@Anke

[Anke]

The question is if this path / file exists. Check that.

[Patryk_F]

@wikki74

But how do I get only the filename and not the path?

This way you will get the file name along with the directory structure.

[wikki74]

@Patryk_F

This way you will get the file name along with the directory structure.

This did not work, but finally i got it working with this:

THANK YOU VERY MUCH @Anke and @Patryk_F

[Anke]

@wikki74

This did not work, but finally i got it working with this:

You replace the ASD plus /kundc/ and add this path back in the copy function.
This doesn't make any sense at all. So this would be the way to go:

Explanation:

[wikki74]

This would not work because I need the "global file" = filename with folder structure also for the CopyAsync funtion (copy toFileName)

[Anke]

It should look like this:

Note: As already said, this will no longer be possible when AI2 targets Android 11 (targetSdkVersion = 30 (Aug 2021 or for updates Nov 2021). Only if no further updates have to be made later would it actually be no problem to do it this way..

EDIT: Of course it should be:

Do it once and do it neatly according to the art and not according to your ideas. In a few months you will find your application not working and waste a week fixing it again. If you already have files downloaded to ASD, why do you copy them to another directory? Leave them in the ASD and load them into the app from ASD.
