In one screen you are not able to done "multitask", and you sew many mobile that are involving in multi tasking function, don't worries now you can use "multitasking" in your any Android device.
Android still doesn't offer proper multi-window multitasking, but you can get it with a third-party tweak. All you need is root access — you don’t have to install a custom ROM.
Multi-window multitasking is found on some Samsung devices, where it only works with specific apps. You can also use special floating apps on any device. The solution here will let you multitask with any app.
Install the Xposed Framework
We’re using an Xposed Framework module here. The Xposed Framework requires root access to install and provides a platform you can install various tweaks for. These tweaks used to require flashing a custom ROM — now you can just install the Xposed Framework, download a module from within the app, and reboot. If you don’t like a tweak, you can disable it and reboot again — simple.
Assuming your device is already rooted, you can download the Xposed Installer from here and side load it onto your device. Follow our guide to installing the Xposed Framework for more information on getting started and using this powerful customization tool.
Install XMulti Window
We’ll be using XMulti Window for this — you’ll need to install the Xposed Framework from within the Xposed Installer app first.
Open the Xposed Installer app, tap Download, and locate the XMulti Window module. Download the module from within this app, enable it, and reboot your device.
Choose Your Apps
Open the XMulti Window app from your app drawer to get started. Tap Sidebar Settings in the app, tap Sidebar App Settings, and use the Add button to add the apps you want to multitask with here. The apps you add to this list will appear in the sidebar so you can open them in split-screen mode.

Launch Split-Screen Apps From the Sidebar
Tap the Open Sidebar option in the XMulti Window app to launch the sidebar, and then swipe in from the left side of your screen. The sidebar will appear at the left side of your screen above other running apps — it functions like a floating app.
To open an app in split-screen mode, long-press the app’s shortcut icon in the sidebar and tap Add to up Work space or Add to down Work space. If your screen is oriented horizontally, you’ll see the Add to left Work space and Add to right Work space options instead.
When you've opened the apps you want to use, swipe down from the top of the screen to open the notification shade and tap the Sidebar Running notification. This closes the sidebar, freeing up your screen space. You can always swipe in from the left again if you want to view the sidebar and open another app.
You’ll then be able to use both apps alongside each other. Here we’re watching a video while browsing the web — the kind of powerful multitasking that’s still impossible on most tablets and mobile operating systems today!
