Android also has "airdrop". It's called "nearby share". Works weekly l exactly the same way so there's no need to WhatsApp it. You can share it right there with all android users.
Look on your phone settings. There's also going to be a nearby share quick toggle if you want to turn it on and off manually.
Also press "share" on a photo and nearby share will be an option. Press it and try it out and learn it.
