Nearby Share works between Android phones and will work with Chromebooks "in the coming months", but it can't share to iOS devices, Macs, or Windows machines.... AirDrop lets you quickly share files with any fellow iPhone or iPad users that are nearby. Google Pixel and Samsung devices will be the first Android smartphones to receive this feature from today.
Google has launched Nearby Share, a feature that will enable reliable and easy sharing of files, links, pictures across Android 6.0, and above devices. Because of these protocols all being available for file transfer, you can also share files to others near you without actually having to share contact info. "The system will then pick the best protocol for the transfer - whether it's Bluetooth, Bluetooth Low Energy, WebRTC or peer-to-peer WiFi" which means you can share files even when you're technically offline. "So after years of development, Android is launching Nearby Share", Google said in this blog post. A dedicated QS toggle for the feature will appear, which you can switch to conveniently use Nearby Share. This will happen through privacy settings as users can select "hidden", visible to "some contacts" or visible to "all contacts" as per their needs. Since the most open setting is visibility to all your contacts, that person would only see you available if your Nearby Share screen is open and ready to receive something.
Google had previously supported a file-sharing feature based on Near Field Communication (NFC) technology called Android Beam, but it removed it with last year's Android 10 update. While we've heard in comments and emails that there are other services that do all this in one way, shape or form, there are no 3rd-party services that will simply be available to every Android and Chrome OS user out of the box in the coming months. The receiver will still have the option to accept or decline the file, so you don't receive files by accident. And in the near future, people will be able to share files, contacts from Chromebook to Android or vice versa.
