IDEs for this purpose (android dev) are not small little text editors that work well with limited resources. Keep that in mind. You will also need to consider things like compilation and phone emulation, which can also be resource intensive.
I highly recommend looking for something that is built with a Linux distro by default. This will make your life easier in the long run, although it may not be a simple task up front if you are not familiar with Linux.
I don't actually have a Linux laptop, it is a desktop, but I use my Steam deck as a Linux laptop, and can almost do everything I want to, although steamos will require some weirdness similar to Windows. I use IntelliJ Ultimate on my steam deck and can successfully work on smaller scale Go and Kotlin projects while running IntelliJ low power mode.
Most larger dev shops (in the JVM world) will just hand out whatever is the current top ~$3000 MacBook pro (for reasons). This leads to a lot of devs using OSx at work and Linux (at home) for personal projects. An apple computer of any type can help prepare for this inevitability, if Linux is out of the options. I personally dislike this, as I am not an Apple fan, but this is what I have experienced.
Although I use Windows for some personal development, there are so many hoops that one has to jump through to get Windows working properly for advanced things, it almost isn't worth it and requires heavy windows development knowledge, and is probably best to just get a MacBook (of whatever type).
Outside of having the dock to allow for normal USB ports for both keyboard and mouse (without converters and such), this awesome steam-deck-tricks readme/repo is majorly where I have been learning from.
The major catch is rootfs read only and strategizing how to avoid reinstalls after steam updates. I haven't quite gotten all the way there yet since I am using it more for tinkering (linux host on local network) for the time being.
