I’m currently also looking at decompiling android apps and understand a bit of smali. If you send me the apk I might look into it.

If you want to do it yourself, I recommend apktool_m on android. It includes all tools required to decompile the app. It can even show a partially correct java code in apps that are not obfuscated.

Is that still a problem in newer java versions? I have to admit I have only written simple things in java.

Java is also memory safe

Please tell me this never worked for the sake of humanity

I think not as the only instance that has your ip is the one you are registered on.
