The N Developer Preview documentation cites a freeform multi-window mode option:
Manufacturers of larger devices can choose to enable freeform mode, in which the user can freely resize each activity. If the manufacturer enables this feature, the device offers freeform mode in addition to split-screen mode.
The docs also suggest that you should test your app in freeform multi-window mode.
However, the two devices that I loaded the N Developer Preview images on (Nexus 6 and Nexus 9) use the split-screen approach for multi-window support.
Is there a way to get freeform mode going on something?
Another device? (e.g., Pixel C)
Settings > Developer Options? (I didn't see anything obvious for this, but I may have missed it)
A specific emulator configuration?
Some
adbcommand?A magic spell, cast by speaking a command backwards?
I am guessing that we might see some hardware that supports freeform mode natively in late May, but I'm just seeing if there's an option to try it out now.
