An Early Look At Android M's Multi-Window Mode For Tablets
Ars Technica has a look at the experimental multi-window mode in the just-announced Android M. It's not a headlining feature yet: "buggy, busted, and buried, but intriguing nonetheless" is how Ars describes it. Android Police is similarly faint in its praise. All that might be true, but to many users even a partly working multi-window mode would be welcome, especially one blessed by Google. (Some Samsung users have had multi-window support for a while, but not built into the OS proper, and multi-window capabilities can be found via app, too.)
Because Android allows apps to run in the background (and I mean actually run, not register to be woken up by certain events as on iOS), we have that already. This will just let you interact with them all at once.
APK quotes people (including myself) without context and should not be trusted. Just thought you should know.
