multi-window for Android

[joe blue]

I use QT on Desktop and android and chromos.
TO run on chromeOS i compile for android. What ChromeOS is us a LXC container to run the android app in a CHroot jail. It has fule hardware access.

Now the issue i have is that to run android apps on ChromeOS, you must support the new freeform MultiWindow API.
The freeform mode introduced with Android 7 allows a multi-window system. Your applications needs to play well within the freeform mode in order to run on Chrome OS , and also Android.
