How To Enable Multi-Window On Android 6.0 Marshmallow

Android 6.0 is a major Android update which brings a number of changes to the core Android system. Google has focused on improving the security of the software, enhancing its performance and making it more intact. In Lollipop we saw Google focusing on the cosmetics, but this time the system level enhancements have caught much of the attention from the developers. Google has embedded some features in the Android 6.0 Marshmallow system which are not apparently accessible but are lying down in the system. One of those features is the Multi Window feature that allows the users to access multiple applications in one same window. We saw this feature coming in Samsung’s TouchWiz UI, but now Google seems to be making this feature a part of core Android system. While this feature is in experimental stages, Google has locked it down which makes it unaccessible for naive Android users. If you’re an Android power user, there’s a way for you to get your hands on the Multi-Window feature hidden in Android 6.0 Marshmallow.

XDA recognised contributor Quinny899, and XDA senior member xperiacle have come up with two different methods to enable the Multi-Window feature on Android 6.0 Marshmallow. The method by Quinny899 requires you to go through a little-longer method. It requires you to have a custom recovery using which we will mount your Android system with your PC and pull the build.prop file to edit it. The method introduced by xperiacle seems to be much easy and much more suitable. It only requires you to have root access on your Android 6.0 Marshmallow powered device, you will only need to add a single line code in your build.prop file which will activate the Mutli-Window feature on your Android 6.0 Marshmallow.multie window android marshmallow
