looks like if I avoid using anything what depends on `Path` in routing it works fine which was just ```static files File root ``` in my case

Android grin

cy · Answer

Perhaps we need to support Paths as well This is my bad we simply didn t try to make it work on Android at all

cy · Answer

File should work

iirc java s Path is java1 7 so not really Android Studio supports just most of syntax features but not the API this needs to be API26+ if I m not mistaken to have full 1 7jvm

< cy> is there some simple way to have ^^ `static` in my case I wrote this ```fun Route supportFiles folder File fun File combine file File = when this == null gt file else gt resolve file val pathParameterName = static content path parameter val dir = staticRootFolder combine folder get $pathParameterName val relativePath = call parameters getAll pathParameterName joinToString File separator return get val file = dir combineSafe relativePath if file isFile call respond file readBytes ``` and then ```static supportFiles File root ``` which works fine but it s just quick copy amp paste of the ktor code with explicit file reading
