Android System Programming Pdf Free Download

Android system programming requires the software and hardware knowledge necessary to work on system-level programming. Therefore, the Developers must employ different techniques to analyze the various components within the devices of their choice. Despite all the difficulties, there is usually an extensive learning curve to acquiring the relevant information in this field.

A separate group of people is developing the layers underneath the Android framework. They are frequently called Android system developers. In contrast with Android developers of apps, Android system developers use C/C++ as a programming language and assembly language to create device drivers and system services.

Moreover, the potential for Android System development remains more uncertain than the Android development of apps. The development tools and environment used for Android application development are easy to understand.

Requirements of Android System Programming

To build Android System Development, we can utilize an Android NDK to create Android systems-wide or native apps. Many people consider Android Open Source Project (AOSP) Android system development. However, Android system development involves developing native app drivers, services, or other applications for devices running a particular hardware platform. It is closer to the hardware and the operating system, whereas Android application development is more general and hardware-independent.

Due to the OS’s dependency on its hardware and OS, it is harder to teach Android system programming than Android applications. Given the number of books available, this is clear. It is easier to begin introducing Android application development by providing specific examples. Moreover, People reading books on application programming can follow the guidelines and test the apps using the most available Android devices.

However, many Android systems programming books cover general ideas. If authors want to provide examples, they must be able to relate them to specific devices and an Android version. It makes it difficult for the reader to follow precisely the same process.

The initial part of Android System Programming Pdf focuses on how to customize, expand and port the Android system. We will utilize the Android emulator as physical hardware to show how you can customize and extend the capabilities of an Android system. In addition, learn how to incorporate the ARM translator (Houdini) into the Intel emulator based on x86 and how to include Wi-Fi support into the Android emulator.

Second Section of the Book

In the second section of this guide, we’ll discover how to patch or update an unreleased system with the help of recovery. In this chapter, we will present an overview of healing first. Following that, we will look at how to create recovery for the x86vbox device.

Therefore, With the help of recovery for x86vbox devices, we will show the process of flashing an update pack to alter the system’s image. We will use examples like the Gapps and the Xposed groups to show how to change the Android system image using third-party recovery software.

Chapters of the Book

Chapter 1: Introduction to Android System Programming covers the system’s Android programming basics. It also describes the purpose of this book.

Chapter 2: Setting up the development environment gives information on the development environment to support AOSP programming. Once we have established our development environments, we’ll make the Android emulator for testing our configuration. Apart from the environment configuration, we will also discuss how to build the source mirror of your code of AOSP by using GitHub for you to change between various formats easily.

Chapter 3: Introducing Kernel, HAL, and Virtual Hardware cover an introduction to the Linux kernel, Hardware Abstraction Layer, and virtual hardware. The chapter looks at the various layers of the Android system software stack related to porting. We also look deeply into the inner workings of virtual hardware we will utilize throughout the book.

Chapter 4: Customizing The Android Emulator covers the creation of a brand new device called x86emu. We’ll learn how to modify and expand this device over the following few chapters.

Chapter 5: Enabling the ARM Translation and the introduction of Native Bridge explores a new feature introduced in Android 5 Native Bridge. Since we built an x86-based system, x86emu must incorporate the ARM translator (Houdini) into the device to ensure that all native applications running on an ARM will work on it.

Chapter 6: Troubleshooting the boot-Up Process Using a Customized RAM Disk introduces a sophisticated ability to debug problems during the boot-up phase. The well-known Android-x86 project uses the ram disk in a specific way to initiate the boot-up Process. It assists in troubleshooting the device driver and problems with the initial Process very quickly.

Chapter 7: Enabling Wi-Fi in the Android Emulator presents details on enabling Wi-Fi in the Android emulator. The Android emulator can only support the emulator for a 3G connectivity for data; however, numerous applications are aware of data and Wi-Fi connections. This section shows how to enable Wi-Fi within Android’s Android emulator.

Chapter 8: Designing Your Device with VirtualBox examines the best way to port Android to VirtualBox by introducing a new device called x86vbox. The x86emu device will show how to modify an existing application. The x86vbox shows the Process of porting Android to a brand new hardware platform.

Chapter 9: Booting up x86vbox with PXE/NFS will explain how to boot Android on VirtualBox with PXE/NFS. Because VirtualBox is general-purpose physical hardware that is virtual, the initial issue we face is that we require a boot loader that can start the system. We’ll use the PXE/NFS boot option to address this problem. It is a sophisticated debugging capability that you can use in your projects.

To discuss a more advanced case about the PXE/NFS setup using an external DHCP/TFTP server running in the host-only network environment.
