Google Messages is starting to test support for 'Bubbles' conversation on Android 10 supposedly. According to XDA reports Google announced Bubbles alongside Android 10 but decided to leave the feature in the OS for developers to offer a wider, consumer-facing release in Android 11.
While the support for the feature was initially added in the second beta of Android 10 for Pixel devices, it wasn’t released at large on the stable build. Eventually, as per reports suggests, the bubble notification system could completely replace the overlay API in the future.
However, it is yet not clear whether this will be currently rolled out as a regular feature on Android 10 devices for now. With undergoing further testing for better support across other apps it exists only under the Developer Options. It was found that facilitating the Bubbles conversation option with the Developer Options on an Android 10 device makes this more usable in the Google Messages app.
You can go into the notification settings and enable Bubbles in the latest version of the Messages app, version 188.8.131.52. Android 10 users can manually enable Bubbles API from within the “Developer Options: Settings > Developer Options > Bubbles.”
While the feature can be enabled, it may not work all that smoothly, considering it is mainly for developers to test and work on. However, the official release date of the feature hasn’t yet been confirmed.
