How do I port Castlevania from android to pc

[Lufims]

I used apktool to decompile the castlevania sotn apk, and now I don't know what to do with that, someone know how to port the game to pc?

You port it with a lot of knowledge in a preferred programming language. Seriously.

If it was something so simple, it would have been done long ago.

I know what I'm going to say is stupid, but the most sensible way is just installing an android emulator and run that game on it.

My pc doesn't even run youtube with the video in 720p, so I can't run an android emulator

Yeah, i know, but what I need help is some directions to where to go, like, what language should I use (I just made android apps with java, css and typescript, and I have some knowledge in python too), and how can I start to make a port, because i've never did that before.

Since you already have a source code, you can read it and write basically the same game with your programming language in some game engine. Or maybe you can open it in Visual Studio and adjust it to a PC version or something. I don't really know how it works exactly, but I would start with looking that up.

Ok, so, with visual studio I can rewrite some of the code to adapt it to pc, ok, this is a start, and basically I have to use C or C++ to do that, because java code is very slow in pc (I don't know about that, I just heard it somewhere), or something like that

Emulate the ps1 version then.

That sounds like an apples to oranges comparison. I imagine running streaming video is more of an Internet connection problem than a PC problem (that the issue with downloading the data fast enough, rather than execution). But I could be wrong?

What gave you the idea it was written in Java..?

You say you "decompiled the APK", but that probably doesn't mean you have any kind of human-readable code that you can easily rewrite in a different language.

Is Java still used on modern smartphones?

My understanding is that the extent of Java was like mid-2000s flip phones.

I can't even remember since using Java in a programming class circa 2005, does Java even produce binary files or are apps entirely run by interpreting the code?
(my feeling is like, yes, there is a binary level and that it kinda was the point of Java: to create cross-platform programs by means of emulating fictitious hardware)

I think it's possible to get the code, as it says here

And OP said he used apktool, which is required for one of the steps.

Aye, https://en.wikipedia.org/wiki/Java_bytecode

and that it kinda was the point of Java: to create cross-platform programs by means of emulating fictitious hardware

Indeed, if it was written in Java, an Android emulator would not be necessary.

On that note, doesn't Windows 11 run Android apps natively now? Of course, they'll still have to be compiled for x86, which isn't supported by all apps.

One of the answers:

it's not going to return the code you wrote. It is instead going to return whatever the compiler inlined, with variables given random names, as well as functions given random names. It could take significantly more time to try to decompile and restore it into the code you had, than it will be to start over.

Correct, a bytecode is produced by compiling the Java source code, and then a virtual machine interprets it. On Android, I think that VM used to be Dalvik time ago, which was later replaced by Art. No idea if there's a different one currently, as I never went deep into coding for Android, didn't like it very much. Nowadays, it seems that you can code non-native apps using frameworks such as React native or Flutter.
