Is it support Android?

[borisbrodski]

Theoretically yes, but I never tried it. You can try ARM jar for ARM-based Android systems.

[qqli007]

@borisbrodski , I test the library on Mi Note, android os 4.4.4 and It not work. I test it like this: 1.use those libs sevenzipjbinding.jar sevenzipjbinding-Linux-arm.jar

  try {
            SevenZip.initSevenZipFromPlatformJAR();
            System.out.println("7-Zip-JBinding library was initialized");
        } catch (SevenZipNativeInitializationException e) {
            e.printStackTrace();
        }

and the error log:

[You may also try different SevenZipJBinding initialization methods 'net.sf.sevenzipjbinding.SevenZip.init*()' in order to solve this problem]

Do you have any idea with this?

[borisbrodski]

Look's like we experience this issue: https://code.google.com/p/android/issues/detail?id=10076

#7 [email protected] OK - I now understand android a little better now. I normal java you can locate resources (via the classloader) by bundling them in with the class files and then making a java archive. Android creates the dex from the classes and any resources get thrown out unless explicitly referenced by apkbuilder using '-rf' for the root resource dir and then the resources are saved as a tree at the base of the apk file.

It's a real shame that your documentation doesn't specify this in both ClassLoader and ResourceBundle - it would save the few a lot of time!

Thanks for the pointers ... best, Nick

I will have to rewrite initialization algorithm for Android later.

But for now, could you please try to load the ARM native library manually? Just extract sevenzipjbinding-Linux-arm.jar and put the library into resources directory. Then load it manually like this

System.load(libraryPathAndFileNameOnAndroidDevice);
SevenZip.initLoadedLibraries();
System.out.println("7-Zip-JBinding library was initialized");

[qqli007]

@borisbrodski ,I do it like this:

System.load(Environment.getExternalStorageDirectory() + "/Download/lib7-Zip-JBinding.so");
            SevenZip.initLoadedLibraries();
            System.out.println("7-Zip-JBinding library was initialized");

but it has err:

[arpitkh96]

I tried the same thing .ended up with

FATAL EXCEPTION: main java.lang.UnsatisfiedLinkError: dlopen failed: library "libdl.so.2" not found at java.lang.Runtime.loadLibrary(Runtime.java:372) at java.lang.System.loadLibrary(System.java:1076)

[borisbrodski]

Thank you. I consider Android support very important. But it will need some afford to make it happen.

Any help is appreciated!

[arpitkh96]

Yea ask it anytime

[borisbrodski]

Thank you!

[slapolt]

I got the same error (.... java.lang.UnsatisfiedLinkError: dlopen failed: ...) There are some solution?

[borisbrodski]

There is actually a successful port to Android made by seven332: https://github.com/seven332/sevenzipjbinding/tree/migrate-to-15.09-try2

You might give it a try!

(I will encorporate it into the official 7-Zip-JBinding in a while.)

[slapolt]

Thanks for the quick response. I need to unpack only - arj. In the link I see tar, zip, 7z ....., but I do not see arj. :( Something missed, or is not there?

[borisbrodski]

7-Zip-JBinding does support ARJ. Check the ArchiveFormat enum here: https://github.com/seven332/sevenzipjbinding/blob/migrate-to-15.09-try2/jbinding-java/src/net/sf/sevenzipjbinding/ArchiveFormat.java

[MSDarwish2000]

Thanks for your great library. It's very useful for me, but I have a bug with a certain file which I can extract using other apps normally. I get ExtractOperationResult.DATAERROR. I am using seven332's port to android. This is the archive I'm trying to extract. http://www100.zippyshare.com/v/n5VRzhIV/file.html Thanks in advance

[borisbrodski]

Thank You for the report. I'm on vocation right now (with no laptop in sight!). I will be back in two weeks. Please, drop a small reminder message here, if don't  get response by the time. Thank you! Cheers,Boris

Hello borisbrodski. Is this project support Android? Hope for your reply!
