Unzip

Frankly I do not know, to create my application B4J I had to create a library to compress and decompress that B4J is not found.

I used Inline Java with the native library java.util.zip. *;
Then I thought about rewriting it for B4A, I did not even see if there were other Zip libraries in B4A.

My library is very simple because I am very limited in java, I suppose @Informatix has created something more complete.

Among other things, the source code of my library can be found within this application that I shared in the forum.

So who wants to make changes can also have the source code.

 

Thanks, I was not sure and I solved this way.
But good to know for future uses

 

hi, @Star-Dust, your lib is working well for me. i have 2 questions.
the zip that is created is also created with the folder scheme as in my phone so if i zip a file in filedireinternel i get all folders to the zip and i have to dig in the zip to find the file itself. would it be possible to filter those folders and add only the file to the zip so when i open it i see all files in it and not inside folders?

question 2, it would be awesome to have a finish zip/unzip event that will be called when app has finished the job.

thanx a lot, ilan

btw. the difference between archiverplus and this lib is that archiverplus crashes on android 8+ and this one works

 

I believe it is possible to make selections and raise a decompression file event.I've simply used a native Java library, they are really 2 lines of code.
But I have to look good, because I do not overdo myself like I did.

Do you dare to java?

 

can you post the class that you converted to b4a lib?

thank you

 

Update 1.02 - Add finish event

 

Perfect thanx a lot !
