How about offering Android jni as standard?

[rabbitson87]

It's great and great to be able to use rust right away.
But when I tried to use Android api, I also had to make a separate adapter using cargokit.
In my opinion, I would like to offer work suggestions for people who will be in the same situation as me.
I'd appreciate your opinion. Thank you :)

Thanks for the feedback :D

It would be great to provide support for more users out there, but may I ask you what do you exactly mean by 'Android API'(Probably Java API) and 'A seperate adapter'? It's kind of hard for me to guess which situation you are in where you had to bypass cargokit.

May I take a look at your 'separate adapter' code, if possible?

The example link I'm trying to implement is here.

And the java file you see here will make it look like the following link.

Thank you very much for considering my opinion :)

This idea looks interesting :) However, it seems to go out of the scope of this framework.

The main questions is as follows: If we support JNI for Android, why not Objective-C interface for iOS, C interface for Windows, etc? It would make this project support various languages other than Rust, which would be a LOT of work 😅.

I can come up with 2 alternative solutions:

• Simply integrating JNI for the specific Flutter app project you're working on
• Creating a Flutter FFI plugin: Flutter does a pretty good job with supporting development of native Flutter libraries that use different mechanism depending on the OS. This is possible with 'FFI plugin', which we are free to develop ourselves.

I thought I could do most of the rust in the project you made!

Flutter is a cross-platform, so most of them are supported.
That was good !! Of course, it will take a lot of time as you said, but I thought it would be nice to apply gradually.

If you say you're applying, I'm going to participate in the work. Thank you for listening to me.
Even if I don't, I'll continue to use this project !! :)

IMHO, writing your Rust-Java FFI as a Rust crate and publishing to crates.io would be great, since then we can use that in any Rust project. What do you think about this idea? It would be much more generally available, even for those who are not using Rust-In-Flutter ;)

[rabbitson87]

That's great!

I'll let you know after I make an android ffi package with functions declared as declared function!
Thank you for a good idea.
I'll let you know if there's good news!! :)

Looking forward to see your project on crates.io!
