You are right accessibility is not supported by those 2 frameworks and that's an issue.
One of the applications I wrote simulate a LED protocol and so you just need to launch it and then use it over the network from a server.
These are meant for use in games that already do this. They are not suitable for building regular apps.
How do you even compile C code for Android / PlayStore?
Debugging is working smoothly, I was surprised how good the experience was.
My setup is that Window run in a VM (Parallels) from macOS.
I can then open the iOS code from XCode and the Android from Visual studio and switch very quickly between the targets.
In that way, I always commit versions that I already tested and debugged on all the targets I need to support.
Android NDK
The Android NDK is a toolset that lets you implement parts of your app in native code, using languages such as C and C++. For certain types of apps, this can help you reuse code libraries written in those languages.
I made applications with Nuklear that runs on Android, iOS, macOS, Windows and share the same main C code. For me, it's a dream come true if you create a cross-platform application that needs a simple GUI.
Dear ImGui is also fantastic and more complete than Nuklear.
What I like a lot with Nukear and Dear Imgui is that you have a GUI that is GPU accelerated and so can be updated at 60 FPS without burning resources.
