Building Android Conversation Bubbles

Building Android Conversation Bubbles

摘要

We recently rolled out support for Conversation Bubbles for DMs and Group DMs on Android 11.

In case you’re not familiar with Conversation Bubbles, take a look at the video below. Basically, they are a way to pop out a conversation from a notification into a Bubble that will draw over other apps, making multitasking while chatting easy and comfortable.

This post will describe how we built support for these bubbles, the challenges we faced along the way, and how we overcame them. Some details were simplified where it made sense to, but stayed relatively close to our actual implementation overall.
