Use Java library in Unity

Question

Hi everybody,

I made a Java library and I would like to be able to use it in Unity 3D, and not only for Android devices, but for iOS as well.

I saw there are some tutorials on the Internet about doing a plugin for Android, but no one on how to use Java library in Unity.

I tried by converting my .jar in a .dll file. I can access my library methods, but it only works when I export my game for Windows devices. So, is there any other way to access my library methods on every device?

Thanks!

The other approach to cross platform is to do your Android and IOS coding in C# using Xamarin.

As long as you keep your library to the limits of what Unity knows, it will work in Unity or native on PC/OSX/Linux/Android/IOS and Unity.

To see an example of a cross platform project done t$$anonymous$$s way, see: http://unseenu.wikispaces.com/AnyGUI

+1. Yeah. But while using Xamarin, staying in the limits is the main thing you need to remember. And this is one of the reasons why libgdx shifted to libgdx RoboVM backend from Xamarin. Plus there is also the reason of cost involved with Xamarin since not everyone can afford that cost. ;-)

You might find t$$anonymous$$s question on SO of some help: Can I access Java code from Unity?

OK, thank you. But do you know if it's going to work on iOS as well? I have tested it on my Android device, and it works, I can access my classes and methods. I can't test it on iOS devices for now...

Thanks! :)

I'm not sure if it will work or not and I also don't have an iOS device. If you get to try it let us know the outcome for sure. :-)
