Android system architecture
Android System Architecture Last Updated: 06-02-2018 The Android softwarestack generally consists of a Linux kernel and a collection of C/C++ librariesthat is exposed through an application framework that provides services, andmanagement of the applications and run time Android system architecturecontains the following components: Figure 1. Android system architecture.Application framework.The application framework is used most often byapplication developers. As a hardware developer, you should be aware ofdeveloper APIs as many map directly to the underlying HAL interfaces and canprovide helpful information about implementing drivers When we talk aboutAndroid architecture, we mean how the Android system has been designed,segmented into layers, and built up to work as a system. Building such acomplex system requires careful structuring to ensure all the components worktogether cohesively. Its architecture ensures that the many componentsfunction as a whole without crashing

The Android Software Stack. Android is structured in the form of a softwarestack comprising applications, an operating system, run-time environment,middleware, services and libraries. This architecture can, perhaps, best berepresented visually as outlined in Figure 9-1 Android architecture is a stackof software components. It is in the form of a software application, operatingsystem, run-time environment, middleware, native libraries and services. It iscategorized into five parts as below: 1. Linux Kerne Architecture Diagram.Here is the Android Architecture Diagram, obtained from here.. See alsoAndroid internals diagram. Basically Android has the following layers:applications (written in java, executing in Dalvik) framework services andlibraries (written mostly in java Android 10 or higher converts selectedsystem components into modules, some of which use the APEX container format(introduced in Android 10) and some of which use the APK format. The modulararchitecture enables system components to be updated with critical bug fixesand other improvements as needed, without affecting lower-level vendorimplementations or higher-level apps and servicesAndroid Architecture Components Part of Android Jetpack. Android architecturecomponents are a collection of libraries that help you design robust,testable, and maintainable apps. Start with classes for managing your UIcomponent lifecycle and handling data persistence Platform Architecture.Android is an open source, Linux-based software stack created for a wide arrayof devices and form factors. The following diagram shows the major componentsof the Android platform. Developers have full access to the same frameworkAPIs that Android system apps use Android Inc. was founded in Palo Alto,California, in October 2003 by Andy Rubin, Rich Miner, Nick Sears, and ChrisWhite. Rubin described the Android project as tremendous potential indeveloping smarter mobile devices that are more aware of its owner’s locationand preferences. The early intentions of the company were to develop anadvanced operating system for digital cameras, and this. Android architectureis a software stack of components to support mobile device needs. Androidsoftware stack contains a Linux Kernel, collection of c/c++ libraries whichare exposed through an application framework services, runtime, andapplication. Following are main components of android architecture those arOur choice is motivated by the fact that, according to market research 49.2%of mobile devices sold worldwide in 2012 have used Android SystemArchitecture. The implemented games are time. The Android software stack asshown in ﬁgure 1.1 can be subdivided into ﬁve layers: The kernel and low leveltools, native libraries, the Android Runtime, the framework layer and on topof all the applications.

1. 2. Architecture in object-oriented words for a monolithic app can be simply described as the placement of classes in the system and how they communicate. We draw an overview of roles and responsibilities of these classes while grouping them 3. The Moto Mod system and architecture achieves this by implementing many of the protocols that are native to the Android OS. This relieves the developer from having to write special-purpose Android kernel drivers, framework updates or a unique application to create a fully-functional and commercial-grade Moto Mod Android Low-Level System Architecture Before you begin porting Android to yourhardware, it is important to have an understanding of how Android works at ahigh level. Because your drivers and HAL code interact with many layers ofAndroid code, this understanding can help you find your way through the manylayers of code that are available to you through the AOSP (Android Open SourceProject. these systems evolve over time, the architecture model of the systemneeds to be derived from the system itself, so that all communication pathwaysthroughout deployment can be analyzed as the system changes.

Android Architecture – Software Stack of Android
In the previous tutorial, you learnt what is Android, different versions ofAndroid and what features it supports. Now that you have basic understandingand knowledge about Android, in this tutorial, we will study about AndroidSoftware Stack (see the diagram below) which will help you to understand howAndroid works inside a device.The Android operating system follows a layered architecture approach. Allthese layers are responsible for different roles and features that we havediscussed below.* * *
Android Runtime (ART)
* Designed to run apps in a constrained environment that has limited muscle power in terms of battery, processing and memory. * Since Android 5.0, each app runs in its own process within its own instance of ART virtual machine, which makes process management more crucial. * ART uses `DEX` files, which is a type of bytecode, specially designed for Android, which helps ART to manage memory more efficiently. * Contains set of core libraries that enables developers to write Android Apps using Java Programming. * Prior to Android 5.0, Dalvik was used as Android runtime. * ART is capable of both Ahead-of-time (AOT) and Just-in-time (JIT) compilation. * It also has a very efficient garbage collection.* * *
What Is the Android Operating System?
The Android operating system is a mobile operating system that was developedby Google (GOOGL) to be primarily used for touchscreen devices, cell phones,and tablets. Its design lets users manipulate the mobile devices intuitively,with finger movements that mirror common motions, such as pinching, swiping,and tapping. Google also employs Android software in televisions, cars, andwristwatches—each of which is fitted with a unique user interface.
Understanding the Android Operating System
The Android operating system was first developed by Android, Inc., a softwarecompany located in Silicon Valley before Google acquired it in 2005. Investorsand electronics industry analysts have questioned Google’s true intentions forentering the mobile market space since that acquisition. But in any case, soonthereafter, Google announced the impending rollout of its first commerciallyavailable Android-powered device in 2007, although that product actually hitthe marketplace in 2008.Since then, software and application developers have been able to use Androidtechnology to develop mobile apps, which are sold through app stores, such asGoogle Play. And because it is developed as a Google product, Android usersare given the opportunity to link their mobile devices to other Googleproducts, such as cloud storage, email platforms, and video services.The Android source code is released in an open-source format to help advanceopen standards across mobile devices. However, despite being released as“open,” Android is still packaged with proprietary software when sold onhandset devices.
Android Operating System vs. Apple iOS
The emergence of Android created a new rivalry between smartphonemanufacturers, with Apple (AAPL) serving as Google’s chief competitor. Tosome, this competitive dynamic mirrors that of the “cola wars” between Coca-Cola (KO) and Pepsi (PEP) over the past 30 years, where no clear winner orloser has emerged. Android was the most popular operating system on mobiledevices as of the end of 2020, with 84.8% of the global market share whileApple’s iOS was in second place with 15.2%, according to International DataCorporation.The increased popularity of the system has also led to a number of patent-related lawsuits, including a lawsuit brought forth by Oracle (ORCL). In 2010,the company alleged that Google unlawfully used Java APIs to develop itsAndroid software. The case was pending as of October 2020.
