As we’ve been expecting since the start of this year, Android is getting a new “Peer App” feature that is available in 12L Beta 1. On phones, it replaces the previous “Split screen” approach to multitasking.

From Recents / Multitasking, tap the icon at the top of the screen to bring up the same menu as before. However, the split screen has been changed to ‘Pin up’, although the same icon is used.

As before, this app shrinks, but now you get the normal map size instead of a shrunken preview. Google has widened the zipper between the two windows, while you no longer get live adjustment. Instead, app icons appear as the background flashes until you stop adjusting.

The big change introduced by App Pairs in Android 12L is the way groupings can be kept in the Recents view rather than the first app pinned in perpetuity. Multiple pairs of apps can be created and accessed, while the common multitasking map features the two icons at the top.

Meanwhile, you can double tap the white divider to toggle / change the upper and lower apps / windows in pairing (h / t Dylan).

Application pairs

Compared to other multitasking approaches, namely Microsoft’s on the Duo, you cannot save a pairing.

This capability is intended for large screens, but there are certain scenarios where it is useful to have it on mobile. Currently, Android 12L beta 1 emulator running on a tablet displays a “Split” button, next to “Screenshot” and “Select”, so that the brand / implementation of the app pairs n is not finalized.
