Can I create a normal android application in Rust with this library?

[jjmornim]

In the "examples" the example is very simple. Can I create a normal android application in Rust with this library? Activities, toasts and so on?

This library is meant for applications that do all the drawing and events handling themselves.

The package will contain only one activity, that is automatically generated by the library. The activity calls (indirectly) the main() function of your program. And that's it. The program is then responsible for drawing everything with an OpenGL or Vulkan context.

That is a good description that probably should go in the readme.

The application type android-rs-glue creates is so-called native activity, which is actually a special case in Android Framework, created precisely for games and other applications which do use not the framework (heavily) but the low-level features like OpenGL, sound, calculations etc. Native activity is really a rare exception of (mostly but not fully) C API in the framework, which is Java API-based. Writing framework applications in everything except Java means duplicating all the Java API in the target language, with the bindings to the original API through JNI. This is a huge work. You can check an example of it for Golang here.
