Best Android Alternative to iOS Continuity

The one good thing, imo, that iOS does is its continuity and handoff with other devices. What are the best ways you've found to emulate this on your devices? Like if I'm actively working on a document or on web pages how can I seamlessly continue using them on my tablet/phone without having to re-open all the tabs or docs again?

Has anyone found a better way?

At the moment I get around this a couple ways:
-Google drive is my primary basic filesystem on all my main computer (desktop/documents/downloads/pictures/videos folders)
-Google Photos on all devices
-PulseSMS for the texting
-Google Chrome which offers a somewhat fix to webbrowsing

But the actual feature of my devices popping up and letting me "carry on" with what I was doing exactly where I was doing it with the click of the button isn't there. Also, the Google Chrome "continuity" is simply the ability to let me go see recent tabs open on my devices and click to reopen them. If anyone knows a way to sync tabs across all my devices (desktop/laptop/phone/tablet) and make them open/close altogether that would be great.
