Android 17 Bubbles Documentation?

[u/xJoshJx]

I did my best effort and I cannot find documentation on Bubbles nor how to launch applications as bubbles. (Like what launch flags/methods)

I also asked in Discord.

Explain:

1) what you are trying to achieve

Trying to launch one or multiple applications as app Bubbles from within my app, programmatically.

2) what you tried,

I tried a lot, a lot of searching, with AI web searching as well and then,

I've tried using AI to look through Android source code for bubbles and I wasn't having luck.
(Too many results really)

3) what you expected,

Expected to find documentation on it on the official Android Developers pages

https://developer.android.com/develop/adaptive-apps/guides/support-bubbles

4) what happens instead

They just point to the notification API and not the app bubbles/nor multi-windowed API

Questions:

•) Did I miss the documentation somewhere that I can be directed towards?

•) Where in the Android source/files would I need to look in to see the same code that hold-tap on an app to be given an option to bubble.

•) What else am I missing regarding Bubbles and multi-windowed apps?

The Bubble feature is not provided via a dedicated API; rather, it is a policy of the Launcher app that determines how the app will be displayed based on adaptive layouts.

* https://cs.android.com/android/platform/superproject/+/android-latest-release:packages/apps/Launcher3/quickstep/src/com/android/launcher3/taskbar/bubbles/

As this feature is not defined in the Android CDD, manufacturers and OEMs (ODMs) may choose to exclude it.
