How to build apk after Show Java?

Question

Java

I decompiled the apk using Show Java, found the file in the phone's memory after decompilation, where you can edit the java code.
Question: how then to shove this folder into the apk and assemble it normally?

Answer 1

No way. Show Java can only decompile.

Answer 2

Maybe I'll point my finger at the sky, but you can try to compile this particular file and replace the previous compiled version in the jar
