Enabling Hidden Experimental Multi-Window Feature in Android 6.0
Android ( root ): If you are one of the lucky few to get Android Marshmallow and you are rooted, you can try the hidden experimental multi-window layout hidden in Android.
This multi-window layout is extremely experimental, so this is your warning. Don’t do this if you don’t know what you are doing. Google hasn’t officially announced this, it’s not supported, and apps are likely to break. However, if you want to play with it, here’s how to enable it:
- Use a rooted file browser to mount a “system” folder in your phone’s memory.
- Open the “system” folder.
- Select “build.prop” and open it with a root-enabled text editor (which should be built into most root file browsers).
- On a new line at the bottom of the file, add the following line:
persist.sys.debug.multi_window=true - Save the build.prop file and restart your phone.
You should now have multi-window mode enabled. To activate it, open several apps and then press the multitasking button. You will see a new icon next to an X in the title bar of apps in the rolodex multitasking wheel. Just tap this icon and choose where you want to move the app. The previous app on your list will fill in the other side.
This feature is not very robust at the moment, which makes sense. It does not have to be activated by anyone outside of Google. However, it is there if you want to play with it.
