An Introduction to Android Developing

The Android Operating System

Android is a full-stack, Linux-based mobile operating system (MOS) programmed in C, C++, and Java, and based on the Linux kernel.

It is developed by the Open Source Project (OSP), Google, and the Open Handset Alliance (OHA). Android as an Operating System (OS) was developed by Andy Rubin, Chris White, Rich Miner, and Nick Sears.

This OS was owned by Android, Incorporated., which was established in October 2003. In July 2005, Android Inc. was acquired by Google Inc.

In November 2007, Google partnered with Intel, HTC, T-Mobile, Qualcomm, and Motorola to form the Open Handset Alliance (OHA).

A week after OHA was formed, it released a preview of its Android MOS. In October 2008, T-Mobile G1 entered the market as the first device running the OHA edition of Android MOS. Currently, OHA is an alliance of handset manufacturers, semiconductor companies, mobile operators, software companies, and commercialization companies.

The Android MOS was preceded by other Mobile Operating Systems, including Windows Mobile for the pocket personal computer (PC) and smartphone.

Other phone operating systems included Bada OS for Samsung smartphones, Blackberry OS for Blackberry smartphones, and Symbian MOS by Accenture for Nokia smartphones.

Finally, of course, there is the Apple iOS. This introduced a sleek graphical user shell for Apple smartphones.

So, why was Android OS created to replace, or compete with, these pre-existing mobile operating systems?

Why Android was Developed?

Android was developed to overcome the demerits of the pre-existing mobile operating systems

The key reasons for the development of Android MOS are as follows:

Creation of a MOS platform

The creation of a MOS platform allowed for the easy development of mobile applications. As expected, Android allows for the fast development of compatible mobile apps. This development process is even faster as compared to similar app development for the iOS platform.

Need for Open Source Licensing of the MOS

The was a need for Open Source Licensing of the MOS for the different companies that manufacture Smartphones.

Currently, Android MOS is distributed under Apache License 2.0 and GNU GPL v2 licenses. The Apache License 2.0 is used for licensing the software and applications developed on top of the Linux kernel of the MOS. The GNU GPL v2 license allows for modification of the Linux kernel.

A stable Linux-based kernel

The Linux-based kernel is stable and can be modified under the GNU GPL v2 License.

This allows for kernel modification to match the hardware of smartphones, and this is a key advantage of Android as any smartphone manufacturer can request OHA for a license to use Android MOS, and then modify this MOS to be compatible with their unique set of mobile phone hardware.

This explains why Android MOS used in different smartphones is well-optimized for these smartphones. The modified Android MOS that is installed in the smartphone is called the stock firmware, which is also popularly described as the stock read-only memory (ROM).

The downside of this open-source licensing is that one cannot take the stock Android MOS used in a specific phone brand and then install it in another phone brand.

Ability to create custom ROM

Android provides the ability to create custom ROM that can be installed on smartphones.

This custom ROM can be created by the manufacturer as the stock ROM, or an individual programmer who understands the hardware in his/her phone. This allows the stock ROM to be modified by an individual programmer.

Highly customizable

Android MOS is highly customizable; and different widgets, launchers, icon packs, and themes can be developed to be installed in the user-space of the MOS.

Computing Platforms

User applications to be used in Android MOS are written in Java. There are several computing platforms for developing and deploying Java programs for running embedded hardware.

The 3 main platforms are:

• The Java Platform Micro Edition (JPME) for Java code that runs micro-controllers and chips in smartphones
• Java Platform Standard Edition (JPSE) for use in PC and Notebooks
• and the Java Platform Enterprise Edition (JPEE) for use with Servers and Workstation computers.

For the smartphone platform, the JPME needs to be configured so as to create a customized profile for a particular category of smartphones and versions of Android MOS.

Full-Stack MOS

As mentioned earlier, Android OS is a full-stack MOS. This means that the OS comes with a software layer populated with applications that allow the MOS to be used outside the box.

This has been made possible by the release of the Android source code by Google, Inc. The source code was released to Android Open Source Project (AOSP), which maintains this codebase to date.

As a full-stack OS, Android MOS has the following layers: Linux kernel, libraries, Android runtime, application framework, and the application (software) layer where the apps are installed and run from.

The set of libraries that allow a user application to communicate and work with the kernel is collectively designated as the middleware of the MOS. In Android, this middleware is formed by the libraries and Android runtime.

The key components of the Android MOS

The key components of the Android MOS are explained below:

Linux Kernel

Android MOS is based on the long-term support (LTS) Linux kernel, with the latest kernel version used in Android 11 being Linux Kernel 5.4 LTS. In this kernel are held the kernel-space drivers, and it handles process management, networking, and memory management.

The main drivers here are the keypad driver, display driver, camera driver, audio driver, Wi-Fi driver, binder driver, power management driver, and flash memory driver.

Programming Languages

Because Android uses Linux Kernel which is written in C programming language, then it is evident that the core Kernel of Android MOS is written in C Language.

Also, some of the codes in the kernel and middleware are written in C++ language. However, the entire graphical shell, or user interface (UI), is written in Java programming language.

Java can access the C code through the Java Native Interface (JNI).

Libraries

Atop the kernel is the library of the MOS. It is made up of the WebKit, SQLite, OpenGL-ES, SGL, SSL, Libc, FreeType, Surface Manager, and the Media Framework.

Android Runtime (ART): It is principally made up of the core libraries based on Java 5 Standard Edition, and the Dalvik Virtual Machine. It shares the same layer space with the libraries.

Application Framework

This allows for components to be reused and even replaced. It is made up of the package manager (which is the Android Application Package [APK]), telephony manager, activity manager, location manager, resource manager, view system, window manager, content providers, and notification manager.

Dalvik Virtual Machine (DVM): It provides the virtual OS layer that user applications can run on, thus allowing different handset models with different hardware to run the same user application. All .dex files run on this DVM.

SQLite

This is used for structured data storage.

Integrated Browser

As mentioned, Android is developed by OHA, of which Google is a member, and thus it is understandable that Android MOS comes with an integrated Google browser which was initially based on the WebKit engine developed by Apple, Inc., but released under an open-source license.

Since 2013, Google forked a component of WebKit called WebCore and then developed it as the browser engine called Blink, which is currently used by 2 web browsers – Google Chrome and Opera.

This means that Android apps that require browser functionality can work well with the Opera web browser.

Graphics

Android MOS comes with optimized graphics powered by hardware acceleration and powerful graphics libraries, including OpenGL, OpenGL ES, and Vulkan for rendering 3D Graphics. SGL is used for rendering 2D graphics.

Media Support

Android MOS supports popular media codecs such as MPEG4, MP3, AMR, AAC, and H.264. It also supports still image formats including JPEG, PNG, SVG, and GIF.

Application Layer

This holds the applications that the user can use. These applications include the browser, phone, launcher, contacts, messages, icon pack, themes, media players, and file manager.

These applications come hard-coded in the Android MOS, thus allowing one to use the phone after booting it up for the first time.

Android 11 and Android 12 Developer Preview

The latest stable release of Android MOS is Android 11, which was released on 8th September 2020. On February 18, 2021, the beta developer preview of Android 12 was released.

Application Lifecycle

In Android MOS, an app must be started and run so that one can use it, and this leads to using of MOS and hardware resources.

When the user finishes using the app, (s)he can stop it so as to free the resources. This process of starting an app, using it, and then terminating it is called the lifecycle of the application.

The life-cycle of any Android application in the smartphone has 3 key phases:

• Active – This state occurs when an app is opened and loaded by the user for use.
• Paused – The app is running but inactive as the user is not using it, but has not yet closed or shut down the app.
• Destroy – The app has been closed, and its operations cease. Also, its cache memory is cleared.

Mobile Application Development (MAD)

AOSP allows programmers to build or develop applications and codebases that can be included in any of the layers of Android MOS.

Most of these programs are built as user applications that are installed in the application layer.
In 2019, Google declared Kotlin as the preferred programming language.

Previously, Java was the preferred programming language, and it is still used to date.

When developing an app, the programmer must ensure that it has the basic building blocks. There are 4 application building blocks:

• Activity that the system matches to an intent.
• Services are the components that run in the background.
• IntentReceiver that responds to an intent.
• ContentProvider allows data to be shared across apps.

Android Development Setup

This is the collection of tools needed to create, test, debug, and deploy an Android it. This setup can be made by one or more of the following:

Android Studio

This is the official integrated development environment (IDE) for building Android apps. It comes with an intelligent code editor, coherent visual layout, build system, real-time analyzer, APK analyzer, and a fast simulator.

It is a complete standalone Android development setup. It supports only 2 programming languages for Android MAD: Kotlin and Java.

Android SDK (Software Development Kit)

This comes with the full set of tools needed for app development and debugging.

It is packaged as a modular SDK, and one needs to download each module using its official download manager, which is called Android SDK Manager. Android Studio comes with Android SDK.

Java Development Kit (JDK)

It is the implementation of JPME, JPSE, and JPEE that comes with a set of tools needed for Java app development and debugging. It also comes with the Java Virtual Machine (JVM).

Eclipse IDE

Eclipse IDE is the IDE for coding Java mobile apps.

Android Debug Bridge

This is used for debugging Android apps.

Emulator

This is the virtual phone where the developed mobile app is installed and then be tested. It is normally based on QEMU, which is an open-source emulator used for hardware virtualization.

It is not needed if Android Studio has been installed, as the Studio comes with its own emulator called the Android Studio Simulator.

The information provided above is introductory to the process of Android application development. So, where can one learn about Android application development? Well, Udemy of course.
