Open source vs. closed source: Mobile devices like desktops and laptops also use the operating system (OS) to run the software. In this article we mostly discuss the Andriod and iOS operating systems. Google developed Andriod Os and Andriod created Ios.Android is an open source device but iOS is a closed source operating system.

Since Android is open and customizable, programmers use it to run devices such as laptops, smart TVs and eBook readers. Can do. Even devices like cameras, navigation systems, and portable media players have Android installations. Figure shows a tablet running Android.

Before users can analyze and edit software, they must be able to see the source code. The source code is a series of instructions that are written in a human readable language, before it can be converted into a machine language (zero and one). Source code is an important component of the free software as it allows users to analyze and eventually edit the code. When a developer chooses to provide source code, the software is said to be open source. If the source code of the program has not been published, the software is said to be a closed source. First released on the iPhone in 2007.

Mobile Application Development

Mobile operating systems do not stand alone products. These are the platforms on which other products can be developed and marketed for use on this OS. Examples of such products are mobile applications, which are easily called apps. Calendars, maps, notes and emails are just a few examples of commonly found apps on mobile devices.

IOS apps were originally designed by Apple. SDK contains many software tools designed to allow external software to write external programs to a specific software package.

Developers who want to build Apple iOS applications will need to download and install Xcode, Apple’s officially integrated development environment (IDE). The X code, shown in Figure 1, can be downloaded for free and allows developers to write and test their iOS apps in the iPhone Simulator. EOS requires the annual iOS Developer Program subscription fee to be loaded and run on the original iOS device.

Many of the items mentioned in the Google Android SDK are listed for code, as well as numerous tutorials. Supports a variety of Android SD development platforms, including Linux.

Home screen items

Like a desktop or laptop computer, mobile devices set up icons and widgets on multiple screens for easy access. A screen is designated as a Home screen, as shown in Figure 1, the additional screen can be accessed by sliding the Home screen left or right.

Navigation icons

Android OS uses the system bar to navigate to apps and screens. The system bar always appears at the bottom of every screen.

Special Enrichment

As a result of the open source code of Android, some manufacturers increase their functionality in Android OS before deploying it to their devices. For example, some Samsung Android tablets have a feature called mini app tray, which contains shortcuts to apps that can be used at any time. Many manufacturers have followed this trend, resulting in apps or GUI elements that exist only on devices manufactured by this particular manufacturer. This chapter focuses on an unmodified version of Android.

Notification and system icons

• Answer a notification by touching it.
