one time download file?
it is possible?
can you please explain with blocks image

vknow360 · April 19, 2020, 2:36am

Yes it is possible.
You have to check that file exists or not.If it does not exists then download it else proceed.

Can I know what you have tried from yourself?

palmare_as · April 24, 2020, 11:43pm

when I use the FilelistAsync method the application closes

vknow360 · April 25, 2020, 12:52am

Thank you.
Can you please check copyfileasync and movefileasync methods?

e_sorrentino72 · April 25, 2020, 8:16am

With movefileasync it closes

vknow360 · April 25, 2020, 10:18am

Thank you @e_sorrentino72
Now I found the problem.
Actually this is because of AsynchUtil class from AI.
I am finding another way to run tasks in background.
Hope this will be fixed soon!

Another note or inconsistency: @vknow360 @Taifun

vknow360 · April 26, 2020, 10:01am

I think that’s not a bug.It is bacause of using relative path.
/storage/emulated/0/ returns true because it is your external storage and extension thinks every directory starting with / is either external storage itself or exists in external storage.As we all know / refers to external storage.Even if you will use / then it will return same result.

bodymindpower · April 26, 2020, 10:07am

I didn’t say it was a bug, I was just talking about an inconsistency.
However, the path to the root directory of the external storage
/storage/emulated/0/
is not a relative path, but an absolute path.

vknow360 · April 26, 2020, 10:12am

You are right.
But the problem is that FileTools uses relative file path system.
So ‘/’ refers to external storage and ‘//’ refers to assets directory.

bodymindpower · April 26, 2020, 10:19am

Yes, but also the absolute path:

vknow360 · April 26, 2020, 10:28am

Because if a filename starts with external storage path then it does not modifies that.
For example:
/MyDir >> /storage/emulated/0/MyDir
/storage/emulated/0/MyDir >> /storage/emulated/0/MyDir

bodymindpower · April 26, 2020, 10:30am

Yes, I am aware of that.

Btw, I’m not a fan of relative paths at all. They only bring trouble and confusion. See for example the File component:

There the relative and sometimes the absolute path is used. Why not do it consistently in the same way everywhere?

vknow360 · April 26, 2020, 10:37am

I too don’t like using relative path in my extensions but if I shall not then users have to use a file extension to get path of external storage.
That’s why when I had released FileTools it was using absolute path system.

@Taifun can answer it betterly.

Btw , community’s mysterious notification bug is here

Lily · April 26, 2020, 10:40am

Please help me I have PM you concerning this issue.

bodymindpower · April 26, 2020, 10:50am

Sorry, but this explanation is somewhat opaque.

vknow360 · April 26, 2020, 10:53am

I mean there is not any other method to get path to external storage.
/storage/emulated/0/ and /sdcard do not work on all phones and /mnt/sdcard works but some components don’t support it.
