Android Question Permission Problem?

[spaceman]

Hi

I am trying to use the Archiver library to create a ZIP File,
and when I run this code:

Dim O_Archiver As Archiver
O_Archiver.ZipFolder("/sdcard/Alarms/","/sdcard/","MyFirstZIP.zip","NoneForNow")

I get this error:

Is this a permission problem?
Should I add anything to the project?


Thank you

Did you try mnt/sdcard/Alarms?

also check the manifest.

Add the following line to the manifest file using the manifest editor:

< uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>

You should use File.DirRootExternal instead of /sdcard. The actual path is different on different devices and it will add the permission automatically.

Hi Giga and Erel.

Thank you.

Did you try mnt/sdcard/Alarms?

When changing to that, it did not help.

also check the manifest.
Add the following line to the manifest file using the manifest editor:
< uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>

when adding that Permission in the Manifest, it did help..
(both with the "/sdcard/" path and the "/mnt/sdcard/" one)

You should use File.DirRootExternal instead of /sdcard. The actual path is different on different devices and it will add the permission automatically.

This indeed also helped. When I changed it to:

O_Archiver.ZipFolder(File.DirRootExternal&"/Alarms/","/sdcard/","MyFirstZIP.zip","NoneForNow")

It worked.
(when using File.DirRootExternal, I do not need to add the Permission to the manifest..)


BTW
"DirRootExternal" sounds like the path to the external SD Card no?

In my case, I do not have an SD Card in the device,
but If I add one, will File.DirRootExternal resolve to something else?


(if not, then, if File.DirRootExternal="/mnt/sdcard", what will refer to the External Storage(SD Card) when it's available?)


Also it makes me wonder:
Archiver's .ZipFolder() method does not include the needed permission?
File.DirRootExternal causes it to be included, so shouldn't Archiver.ZipFolder() include it too?

 

[Erel]

File.DirRootExternal points to the default "external storage". On almost all of the devices this is an internal storage and not a real sd card.

File.DirRootExternal points to the default "external storage". On almost all of the devices this is an internal storage and not a real sd card.

So what Enum points to the SD Card (when one exists in the device)?

 

[Erel]

There is no API in Android to find the second external storage if such exists. There are several discussions in the forum about this issue. There are some common paths.

 

[spaceman]

OK I understand.

And regarding this question:

Archiver's .ZipFolder() method does not include the needed permission?
File.DirRootExternal causes it to be included, so shouldn't Archiver.ZipFolder() include it too?

Maybe Archiver.ZipFolder() should be updated to include the needed Write permission?

 

[Erel]

No. The permission is only needed if you access the external storage. It will be added when you use File.DirRootExternal or File.DirDefaultExternal.

 

[spaceman]

OK I understand.


1 more thing I am trying to do:
I need to ZIP a collection of files and folders into one ZIP file.

Currently I can only ZIP files, or 1 folder.
Is there any chance this library can be updated to include a method that will be called for example
.ZipItems(),
which will receive an array of items,
(items can be either files, or folders.. foler will end with a '/'),
and that way a developer will be able to ZIP all items to one ZIP file?
