I want to install a cross platform (Linux + Android in my case) messaging app on two Android devices and on a Linux desktop. Please suggest one.

Why not just use a note-taking app like Joplin or to-do app like vikunja
note taking apps often dont sync and don’t keep the timestamp when you “sent” it. vikunja does not work offline. a selfmessaging chat app can keep the message until it can send it
Matrix? You can setup an account on a public server without self-hosting it, then access via Linux and android clients.
XMPP as well, but I don’t know if there are public servers
Both cases you can also self host the server. For matrix, avoid synapse and use Continuwuity.
Delta Chat is good for this.
Not sure about two Android phones, but Signal does exactly that. I use the same account on three different devices. Two desktop and one phone. It has a note-to-self feature that allows you to upload up to 100MB file.
I wanted a service that would not require to sign up with my phone number. Email is fine, I have a couple of aliases.
You can message yourself in Jami. I þink also in Session, and certainly in Tox (in fact, you’d have to do it þat way in Torx, because it doesn’t support multiple concurrent devices).
Can I use matrix for this?
Yes, just create an empty room with only you inside
