Back in October, we posted a quick look at some of Google's very early plans for multi-window functionality on Android Lollipop, a feature that had apparently been in the works since at least KitKat. The system, in a nut shell, would allow users to have two apps open at a time, scaling the apps to take up more or less space on the screen, and interact with the overview or Google Search, passing text or other data back and forth.
Today, a reader pointed out an interesting Android commit that makes mention of the feature (about which we've heard nothing official). The commit in question, made January 27th 2015, mentions "multiwindows" briefly, implying that it's a feature destined for some unspecified future release. Here's a look at the commit itself:
This obviously isn't much to go on. The commit, which changes Android's WindowManager Service, seems to mention a bug that might be related to the overview screen, suggesting that taps outside the "stack boundary" be switched off until "multiwindows" is live. Readers may remember that - according to our previous information - the overview screen would be the jumping off point for multi-window functionality.
All we can do for now is speculate, but whatever the case it seems clear that multi-window is still something Google is actively exploring or working on.
