What Is Multitasking in Smartphones?

Understanding how multitasking works on the iPhone and Android

A multitasking operating system can run more than one program or app simultaneously. To do so, the OS must diligently manage how instructions and processes are handled in the microprocessor, and how their data is stored in the main memory. There’s multitasking on iPhone and Android smartphones, but it doesn’t work the same way as on computers.

Multitasking in Smartphones

Apps in smartphones that run in the background do not always display multitasking. They can be in three states: running, suspended (sleeping), or closed.

When an app is in the running state, it is in the foreground and you are using or interacting with it. When an app is running, it works more or less like apps do on computers, its instructions are executed by the processor as it consumes space in memory. If it is a network app, it can receive and send data.

Most of the time, apps on smartphones are in the suspended (sleeping) state. This means they are frozen where you left it; the app is no longer being executed in the processor and the place it occupies is in the memory. In this case, the data it holds in memory is temporarily stored on secondary storage (an SD card or the phone’s extended memory—analogous to the hard disk on a computer).

When you resume the app, it returns you to where you left off, rescheduling its instructions to be executed by the processor and bringing back the hibernating data from secondary storage to main memory.

Multitasking and Battery Life

A sleeping app consumes no processor power or memory, accepts no connection, and consumes no additional battery power. This is why most apps for smartphones adopt the sleeping mode while asked to run in the background; they save battery power.

However, apps that require a constant connection, like VoIP apps, should be kept in the running state, which drains the battery. This is because if they are sent to sleep, connections will be refused, calls will be declined, and callers will be notified that the recipient is unreachable.

Some apps must run in the background, performing real multitasking, like music apps, location-related apps, network-related apps, push notification apps, and especially VoIP apps.

Multitasking in the iPhone and iPad

It started in iOS with version 4. You can leave the running app and switch to a background app by going to the home screen. Notice here that it is different from closing an app. If you want to resume with an app in the background, you can use the App Switcher, by double-pressing the home button. This brings the focus to an array of app icons currently in use while blurring the main menu. The icons that appear are those left open. You can then swipe to run through the list and select one.

iOS also uses push notifications, which accept signals from servers to awaken apps running in the background. Apps receiving push notifications cannot go to sleep completely because they need to remain in the running state to accept incoming messages. You can choose to close apps in the background by using the long press.

Multitasking in Android

In versions of Android prior to Ice Cream Sandwich 4.0, pressing the home button brings a running app to the background, and long-pressing the home button brings up a list of recently used apps. Ice Cream Sandwich 4.0 changed things a bit.

There is a prominent recent app list that gives you the impression of managing the apps, but that’s not the case. Not all apps in the recent list are running—some are sleeping and some are closed. Tapping and selecting one app in the list might spring up from a running state, or it might wake from a sleeping state, or load the app afresh.

Apps Designed for Multitasking

Some apps are designed to work in a multitasking environment. An example is Skype for iOS, which has new capabilities for handling notifications and remaining active in the background while using minimal battery power. Skype is a VoIP app that allows voice and video calls and needs to remain active always for a better user experience. This works much like a mobile phone, which is always checking for signals from incoming calls and text messages.

Some users want to disable multitasking on their devices, probably because they find that apps running in the background slow down their machines and consume battery life. This is possible, but operating systems do not give easy options to do that. For iOS, it may require jailbreaking the phone.

Программа норм, но нужно ей:
1. Русский язык.
2. Чтобы она работала как в Samsung Galaxy Note 2.
3. И чтобы это приложение было связано со встроенными. То есть: Чтобы у приложения не был собственный браузер, а был, например, Chrome.

Очень видео-мануала не хватет к скришотам на Маркете.
Попробовал на Табе 10.1, не впечатлило. Интерфейс а-ля Windows 1, фильм встаёт на паузу при изменении размеров окна, браузер — фуфло! Готов купить, если будут развиваться, стоит — полтинник, для детей Германии не жалко! При выходе из программы она всё равно висит в процессах, хавая при этом 50 метров оперативки,

How To Mul­ti­task in Android Pie

Mehvish

31 Jul 2018

In the last few years, features in smartphones have improved a lot. Whether it is the external appearance (bezel-less and large screens) or the internals (RAM, software, etc.), it’s no surprise that the smartphones are now extremely powerful devices.

Even on 6-inch screens, one can multitask and use two apps efficiently at the same time. Available on Samsung devices for many years now, Google introduced the split-screen feature in Android Nougat. With this feature, you can open two apps simultaneously on the same screen.

In Android Oreo, Google didn’t change much related to the multitasking feature except introducing the picture-in-picture mode (PIP). However, in Android Pie, Google has changed the way you multitask. While the basic functionality is the same i.e. you can switch between recent apps and open two apps on the same screen, the way you access it has changed completely.

So, in this post, we will tell you how to multitask in Android 9 or P.

How To Switch Between Apps

Before Android Pie, one would press the Recent apps button to open the recently launched apps. These apps were arranged in a card layout and one had to scroll vertically to select a new app. Also, we could double tap the Recent apps button to quickly switch between the two recently launched apps.

However, that’s not the case now as one has to scroll horizontally to view the apps. The good thing about this format is that the entire screen of the app is visible now.

To access the recent apps screen, Android Pie has introduced gestures. These are disabled by default but when enabled, the Recent apps button is hidden and a Pill replaces the Home button. However, it’s not necessary to use gestures, you can continue using the traditional Recent apps button.

But if you want to use them, here’s how to enable it.

Step 1: Open device Settings and go to System. Under System, tap on Gestures.

Step 2: In Gestures, you will find the option Swipe up on Home button. Tap on it. Turn the toggle on for the setting on the next screen.

Once this gesture is enabled, you have to swipe up from the lower part of the screen to open recent apps. Then you need to drag the Pill left to right to swipe through the apps. In order to dismiss an app, you have to swipe up on it. Similarly, to quickly switch between the apps, swipe left to right once on the bottom area of the screen.

How To Enable Split-Screen

If you want to use two apps simultaneously on your Android Pie device, you have to use split-screen mode. Earlier, one would tap the split-screen icon in recent apps to minimize them on the screen. However, now the procedure is slightly different and not apparent for newbies.

Step 1: Swipe up on the area where the Pill is present. You will be taken to the recent apps screen.

Step 2: Use the Pill or simply swipe horizontally on the apps to find the app that you have to use in split-screen.

Step 3: Tap on the app icon that appears at the top of the app card. You will get two options — App info and Split screen. Tap on Split screen.

Once you do that, the app will occupy the top part of the screen and the recent apps will move to the bottom.

Step 4: Choose another app from the bottom list to view these two apps in the split-screen mode.

These two apps will now work independently of each other. For instance, you can watch YouTube videos in one app and scroll through your Twitter feed in the other.

To close the split-screen mode, drag the border of the app that you want to view in full screen in order to expand it. The second app will close automatically.

Bonus Tip: View RAM or Memory Status in Android Pie

With Android Oreo, Google removed the RAM status from the settings. While it is present under the Developer options, you can also view it using the memory widget.

To do so, follow the steps:

Step 1: Hold any empty space on the home screen and then select Widgets from the options at the bottom.

Step 2: Scroll down and drag Settings to the home screen. The Settings shortcut screen will open. Tap on Memory.

Step 3: A new Memory icon will be created on the home screen. Tap on it to view the memory status of your device.

Have Fun Multitasking

Google is continuously introducing features that make our lives and work easy. One such feature is multitasking. Now that you know how to do it on Android Pie, have fun.
