Does it support IOS and Android?

[Personuo]

I want to use it in my project immediately, but I don't know if ios and android are supported?

Hey! I never tested before. Please, if you can test it, let me know if it works. Thank you for your suggestion. Be in mind that ImGui has some issues in your core related to mobile

I've just tested on android. It doesn't render anything. Later I'll check the logs

So the error is in loading cimgui.dll on android:

Same here works flawlessly inside the editor but won't render any uimgui once build ( app runs fine on its own ) tried including the .so with x86 & armv7 file from ImGui.NET-nativebuild/releases ( although I suspect the versions are way off ) , tried both mono and cpp build but still no luck , not very versed with native plugins , maybe someone could figure it out here are a few links I came across : DllNotFoundException on Android , Create a .jar from a .dll

Edit: also tied this older repository which you based yours on ? which had .so files , it's also doesn't work in build - nothing is getting renderer and the console complains about missing dll's as well.

Also tried building my own .so file without any luck so far

Disclaimer: this is a guess.

I read the description of what you did by the link in your last comment, and I think it won't work like that in Unity.
The problem is likely that the code that requires the dll/so is inside the already built ImGui.NET.dll.
I suspect that in order for this to work, all the [DllImport] statements should be resolved and compiled directly by Unity itself.

If this guess is correct then you might probably have success with:

• Copying the source form of the ImGui.NET, including the generated code into the Unity project
• Copying the source code of uimgui (this project) into your Unity project
• Reorganizing the positioning of cimgui according to the default Unity pattern of multiplatform native libraries (see the article referenced below)
• Maybe doing something similar to all the other native dlls used by ImGui.NET and uimgui

In that case the whole project, including the linking information for the native libraries is going to be produced and managed by Unity, which should allow it to correctly include the libraries in the build, and be able to resolve them in runtime.
