Android Question Zip/Unzip Library error ?

[Arnaud]

Hello,

I have published an APP with Zip/Unzip library without problem since 2 year.
All worked fine, but since Android Nougat 7.1.1, I have an user who has a problem with APP.

He has this message:
"java.lang.illegalargumentexception MALFORMED[1]"

I have no problem with the other Android versions.
Do you think the problem is related to Android Nougat 7.1.1 with the Unzip library?

Unfortunately, I have no system with Android 7.1.1 for test my APP.

Thank you for you help.

Is the app in Google Play? Can you post a link?

Which library are you using?

 

[Arnaud]

The APP is in Google Play, "ALFANO Track manager".

https://play.google.com/store/apps/details?id=b4a.TrackManager&hl=fr

It is an APP for database of track for motorsport/laptimer

I use the ABZipUnzip Library(version 1.00)

When this APP is open, please select "ADSGPS" (on the left")

It failed on the first run with this error:

I'm not sure what caused this error, however I recommend you to switch to the Archiver library. It works properly on Android 7.

 

[Arnaud]

Ok thank you very much Erel, my client has the same error.
I check the file de.zip but I think I have a idea.

I change too my library with Archiver library.
Can I send you my new APP after for you can test please?

 

[Erel]

Can I send you my new APP after for you can test please?

Yes. You can send the APK to [email protected].

 

[Arnaud]

Thank you.
I think I have found the error.
In the file "de.zip", I have a file "NÜRBERGRING.track"
The character "Ü" seems to be the problem. I have change it in classic character "U".

I have switched too to the Archiver library.

I send you the new APK by mail.

 

[DonManfred]

The character "Ü" seems to be the problem

OT: Additionally the Track is wrong named at all.

It is called Nürburgring (where the famous Racing Track has it´s home).

 

[Erel]

I send you the new APK by mail.

It works fine on Android 7.

 

[Arnaud]

@DonManfred, yes, sorry it is Nürburgring and no Nürbergring.

Thank you for your help Erel, I send my APP , then I will publish a new version on Google Play.

For anyone who needs unzipping filenames with special characters (made from Windows / Winrar-Winzip...)
SOLVED: Use ArchiverPlus (from ProBundle by Informatix) it handles correctly all special chars in filename while unzipping files (zipped with Windows).

ProBundle

ProBundle contains all the following libraries: - ArchiverPlusZip v1.13 Based on the Zip4j library, this library allows to add, extract, update and remove files from a zip archive. It supports encryption and decryption (standard and AES), Zip64 format and split zip archives. It is compatible...
