71.4 Enabling and using Freeform Support
Although not officially supported on all devices, it is possible to enable freeform multi-window mode on large screen devices and emulators. To enable this mode, run the following adb command while the emulator is running, or the device is connected:
adb shell settings put global enable_freeform_support 1
After making this change, it may be necessary to reboot the device before the setting takes effect.
Once enabled, an additional option will appear within the Overview screen when performing a long press on the app icon as shown in Figure 71-7:
