Just a question... is it possible to patch jar or apk file using JEB..? as far as i know i can only view or decompile jar or apk file.

AFAIK JEB cannot edit APK directly because it requires signing later which is manual.

APK aren't JAR. Unless you do dex2jar and back the other way.

Options are full decompilation/recompile or modifying the java bytecode afaik. Though with dex2jar you could possibly use Recaf's java editor but I recommend v4 if you do it with this way, otherwise apktool -d and modify the bytecode then re-assemble and sign.

If you're looking to patch/modify it another option is Frida too which would allow you to write JS like syntax, you could modify the bytecode to load Frida agent from libs dir of APK when it's started and place all your code there. This is how Oculus Quest apps are cracked.

If I wanted to do this without modifying bytecode and could see actual java code via something like JEB, Frida would be my preferred approach due to the ease-of-use vs trying to manipulate the software via bytecode.

Please re-read Mendax47's question.

My issue, I only read the quoted post after where it was discussing APK and not the OP. Regardless, both were mentioned, and the solutions provided by either of us should work.

It may be caused by the plug-in I use. After deleting the plug-in, I will try again to see if the error occurs! thank you for your sharing!!!

The following error is reported every time it is used. JEB 5.12 will not report an error, but JEB 5.13 and later will report the following error:

Just want to say, thank you for your releases. I find this tool to me quite helpful.

It is not fair how some users are allowed to make thank you posts while others get a huge "violater" stamp when they do the same.
If the rule was made to keep the forum clean, then it should not matter who makes the post. And everyone should be penalized equally.

I cannot use the Generic Unpacker even with the modified version. It still complains about being a demo version. Can anything be done about it?
