How To Know Android Architecture

How To Know Android Architecture

Android is a popular operating system used for smartphones, tablets, and other mobile devices. It is an open-source platform that is developed by the Open Handset Alliance, a group of technology companies including Google, Microsoft, Sony, and many others. It is based on a modified version of the Linux kernel and other open source software. Knowing Android architecture is invaluable if you are involved in developing mobile applications, so here’s what you need to know.

Background Information

Android consists of a few layers that make up its architecture. At the top is the application layer, which consists of apps, such as the ones you can download from the Google Play Store. These applications interact with the Android Runtime (ART), which is composed of a set of tools to compile apps into binary files. It also includes the Android Libraries, which provide APIs that allow developers to access device features such as the touchscreen, camera, and GPS.

Beneath ART is the Android framework, which is responsible for the app’s lifecycle, resource management, and app services. It includes the Android core libraries, which consist of a set of classes to control app functionality. The framework also includes the Dalvik Virtual Machine, which is used to run .dex (Android executable) files. The Dalvik VM is based on the Java Virtual Machine (JVM) and is optimized for mobile devices.

At the bottom of the Android architecture is the Android Linux kernel. This layer controls and manages device drivers, memory, and power management. The kernel is based on the Linux platform and contains a number of important drivers such as USB, Bluetooth, Wi-Fi, and the Linux network stack.

Relevant Data

The Android operating system is one of the most popular mobile operating systems in the world, with more than 2.5 billion active users. It is the most popular mobile OS in the US, with a 52% market share, followed by iOS at 44%. In terms of global OS market share, Android had a 74% share in the fourth quarter of 2020.

Android is an open-source operating system, which means that developers have access to the source code and can make modifications to it. This has helped spur innovation, and many companies have released their own customized versions of Android, including Amazon’s Fire OS, BlackBerry’s BB10 OS, and Nokia’s MeeGo OS.

Android is also highly customizable, making it easy for many developers to develop apps for the platform. Android offers a wide range of APIs, allowing developers to access features such as the accelerometer, camera, and GPS. This has helped to create a vibrant app ecosystem with more than 2.9 million apps and games available on Google Play.

Perspectives from Experts

Experts believe that understanding Android’s architecture can be beneficial for mobile app developers, as it helps to understand the underlying mechanics of the platform. They suggest that developers should become familiar with the Android framework and the Android Libraries, as this will make developing Android apps much easier.

Experts also suggest that developers should familiarize themselves with the Dalvik Virtual Machine as this is the engine behind the Android Runtime. Knowing the Dalvik VM and its limits can help developers optimize their apps and ensure they run effectively.

Lastly, experts believe that Android Linux kernel knowledge is invaluable, as it helps to control and manage the mobile device. Knowing the Linux kernel helps to understand the system’s hardware and software, as well as managing memory, battery, data transfer, and security.

Insights and Analysis

In today’s mobile-focused world, knowing Android architecture is invaluable for developing effective and efficient mobile applications. It is important to understand the different layers of the Android architecture and to familiarize yourself with the tools and APIs available. This helps to ensure that apps run more efficiently and effectively on the platform.

Android’s open-source nature has helped spur innovation and created a vibrant app ecosystem with a huge range of apps and games available. Knowing the Android architecture can help developers create better apps that make use of the latest features, create unique experiences for users, and help their apps stand out from the competition.

Cross Platform Support

Android applications are now supported across a wide range of platforms, from smartphones to smart TVs and tablets. Knowing the Android architecture helps developers to create apps that are optimized for different devices with different sizes and different operating systems such as Android TV, Wear OS smartwatches, and Android Auto in-car systems. This can open up new opportunities for developers and help them reach a wider audience.

Android also supports multiple languages, making it easier for mobile app developers to create multilingual apps. Android Studio, the official IDE (integrated development environment) for Android development, supports the translation and localization of apps into a range of languages. This helps developers to expand their potential market and reach more users.

Developers can also make use of Play Store support, which offers a great way to distribute and promote apps. Google Play Store is one of the largest app stores in the world, and understanding the Android architecture can help developers make the most of these opportunities by optimizing their apps to stand out from the competition.


Security is an important aspect of mobile app development, and understanding Android architecture can help developers ensure their apps are secure. The Linux–based Android operating system has a number of security measures, such as verified boot, Android’s permissions system, and its sandboxing system, which helps to keep devices secure. Understanding these security mechanisms helps developers to create more secure apps.

Android offers a range of tools to help developers create secure apps, including the Android Security Suite, which helps to find security vulnerabilities. Additionally, the Android SafetyNet API can help detect malicious and fake apps, while Google Play Protect scans apps to make sure they are secure. In addition to this, developers can make use of Google’s Play Console to learn more about device health and performance.

Android also offers a range of third-party security solutions, such as antivirus and anti-malware apps that can help to detect and remove malicious apps. Knowing the Android architecture can help developers make the most of these security solutions and ensure that their apps are safe and secure.

Updates and Patches

Android releases regular updates and patches with security fixes, performance improvements, and new features. Understanding the Android architecture can help developers get up to speed quickly with these updates. Google releases monthly security patches for Android devices to help keep devices safe and secure.

In addition to this, Android also releases major updates twice a year, which includes new features such as support for new hardware or improved privacy settings. These updates can help developers create better apps that are optimized for the new features and ready for the target devices. Knowing the Android architecture can help developers get ahead of the curve and ensure their apps are up to date.


Understanding Android architecture helps developers create better mobile apps. It can be beneficial to familiarize yourself with the Android framework, Android Libraries, Dalvik Virtual Machine, and Android Linux kernel. Additionally, developers should take advantage of the tools available to ensure their apps are secure, up to date, and optimized for the latest devices. Ultimately, knowing the Android architecture can open up opportunities and help developers create more effective and efficient apps.
