Android Question [Solved] open/extract a password protected zip file

[AnandGupta]

I need to open/extract a password protected zip file.
I downloaded Informatix probundle https://www.b4x.com/android/forum/threads/probundle-chargeable.58754/

I am trying the ArchiverPlusZip v1.13 Pw, but getting error,

I have attached the zip file of the project.

I understand it is a very old library code and so throwing errors in new b4a 8.8.
I tried but could not fix it. Any solution is appreciated.

Further is there another zip library to open/extract a password protected zip file ?

Regards,

Anand

Cannot create destination folder

does not seems to be a password problem. Do your app has writeaccess to the path you want to extract to?

Hi Don,

Thanks for quick reply.

The attached project (1 post) is the example from probundle. The error is in the example project itself. I am just trying to build and run it to study it. But it is giving error (1 post) both in emulator (24) and redmi 4 mobile.

If you can find time to run the example, please guide if any changes I have to do to run the example itself.

Regards,

Anand

Do NOT expect me to update a few years old example which was not my example!

Create your own Example using targetsdk 26, runtimepermissions and all this.
The Archiver CAN handle password protected zips.

Thanks for your kind help

Thanks a lot, Don.

Your kind guidance helped me and I was successful in achieving my goal.

Attached is a working app, in B4A 8.8, to extract a password protected zip file using Informatix's fantastic library.
It may help members in similar situation.

Regards,

Anand
