Failed on apktool 2.3.3

Hi,

I just update APKRepatcher_lib/apktool/apktool.jar with the new Apktool v2.3.3
but the program failed to decompile and freezing if I try to open apk file...

Thanks.

Cannot run javac

I cannot seem to figure out what this error means when I try to recompile/save the apk.

Could this please be looked into? Here is a picture https://i.imgur.com/2rf18ZX.png

[Request] Allows to change font

Hi, since most of the outputs are source code, it might be better to use fonts like "Courier New" or Courier when editing/viewing those source code, since it's easier to looked at because each character have the same width and it's easier to differentiate between uppercase I, lowercase L, and number 1.

So i was hoping to be able to change the font.

Thanks in advance.

Any plans on updates?

I find this tool very helpful. it's really sad to see no updates in 2 years. I'm not able to create a SystemUI project because of the outdated tools included. Would be great if anyone could update them. Many thanks.

I would have liked to debug this but i have not too much esperience in java and i can't build it properly. If you can show me how maybe i can help you to fix this issue.

I can share the apk in a private way.
If you need other information just ask.
Thanks.

Javac problem

When compiling , the javac command is :

javac -cp .:/home/XXX/Documents/APKRepatcher/Projects/XXX.apk/modifiedJar/;/home/XXX/Documents/APKRepatcher/APKRepatcher_lib/userLibrary/* XXX.java

BUT there is a ';' which must be replaced by a ":" otherwise the order is not good

No more update to this ? particularly those supporting programs/libraries ?

Because the way the libraries are organize, it is difficult for use to even update those supporting programs and libraries. Jadx in particular, needs to have an easy way to be upgraded.

Critical...Bug

Missing information about apk

Hello, I see program shows original name of the apk but could You add also apk's original package name? During decompiling I use to search direct path of the apk project, sometimes I don't want preview additional libraries.
