android - E/Volley: [2458] NetworkDispatcher.processRequest: Unhandled exception java.lang.RuntimeException: Bad URL

Question

I'm trying to connect to database server via android.

My question is can I somehow use localhost url like this:

private const val ROOT_URL = "http://localhost/android/v1/"

Instead of providing my computer's IP address? This is my school project and I have some concerns when I present it something will not work because of the different IP.

I've already tested it like this:

private const val ROOT_URL = "http://IP/android/v1/"

And everything works. So my only question is can I replace the IP address with something static that doesn't need to be changed when I connect to another Wi-Fi network

There is errorlog when I use 'http://localhost/android/v1/' or 'https://localhost/android/v1/':
