Hi 👋Cool project!

How do you compile, debug-run & deploy on android?

marcomq commented 1 year ago

Hi! I used android studio. There is an example project here: https://github.com/marcomq/nimview/tree/main/examples/android Unfortunately, there is no separate or easy cli command.

How are you supposed to build it exactly?

Opening up https://github.com/marcomq/nimview/tree/main/examples/android in Android Studio and hitting build as in the screenshot I get the following log:

Im on Windows 11 if it makes any difference

I also had this or a similar linker issue from time to time. No idea why. Had to perform a rebuilt and then it somehow worked again.
