Coder007 · June 22, 2020, 6:35am

I haven’t tested the apk file of your. I just followed the process of the image, you have posted. My apk is working as it should.

bodymindpower · June 22, 2020, 6:39am

Ok, so where is the problem?

Coder007 · June 22, 2020, 6:44am

These blocks are working as it should. Not an issue so far.

Hi @Coder007
Are you trying to get last modified time of files of phone’s storage?
For me it returns 0L or 01/01/1970 05:30:00 AM only if I provide wrong filename.
Here are my test results:

Try to get last mod time from file’s uri i.e. add file:// before file name.
Because extension uses relative (/ is path to root of sdCard) path only for sdCard and you will have to use uri with files of phone’s storage.

U mean Example: /storage/emulated/0/Download/demo.pdf

I have to add file://before the path, right?

Final : file:///storage/emulated/0/Download/demo.pdf

Am I right??

Coder007 · June 22, 2020, 2:28pm

** Working perfectly.

vknow360 · June 22, 2020, 2:34pm

I was right

Hey is it possible to sort(descending) files according to date of last modification?

Format of last modification date : dd-MM-yyyy

vknow360 · June 22, 2020, 2:45pm

Yes you can do it using dictionary and list utils extension.
First convert all dates in timestamp and store all filenames and timestamps in dictionary.
Now sort timestamps using list utils extension and then get filenames according to timestamp.

There can be a lot of methods to do same and it is one of them.

@vknow360 Copying a file (test.txt) from the assets to external storage does not work with Companion or with the APK.

Example:

/storage/emulated/0/test.txt
relative path: /test.txt

copyFormAssets.apk (5.0 MB)

TaifunFile ext. works. App Inventor Extensions: File | Pura Vida Apps (APK)

bodymindpower · July 8, 2020, 11:30am

I checked it on Android 9 with APK:
It does not work.

copyFormAssets2.aia (63.8 KB)

vknow360 · July 8, 2020, 11:33am

Hi @bodymindpower
CopyFile method does not triggers FileCopied event so you will never get correct result from event.

bodymindpower · July 8, 2020, 11:36am

Yes, but as you can see there is a button (Button3) to check it.

vknow360 · July 8, 2020, 11:38am

I shall check it as soon as possible.

bodymindpower · July 8, 2020, 11:38am

Btw, it works on Android 7 with APK.

vknow360 · July 8, 2020, 11:39am

It also works on Bluestacks in Companion.
I think issue is only on Android Pie and higher versions.

bodymindpower · July 8, 2020, 11:41am

it also works on Android 8.1

bodymindpower · July 8, 2020, 12:51pm

I checked it again on several devices with Android 9 and 10:
It works. The problem with Note8 (Android 9) is now also solved after de-/installing the app.

So it’s working on Android 5, 7, 8.x, 9, 10.
