Every software platform has a foundation, and it's the same for Android. As much as you might think Android is just an app store, it's more than that.
The architecture of this platform goes far beyond what most people think about when they hear the word "Android" or "platform."
So if you're interested in learning more about how Android architecture works, here are five core components that make up the structure of your future apps:
The application framework is the large foundation that enables you to build your app. It provides much of the infrastructure for your app and includes the following:
You can use a core set of components as building blocks in your own applications (such as activities).
An event bus for communication between components within an application.
A security layer to help ensure privacy between applications running on different devices or users of the same device at different times (this is often referred to as "user isolation")
Now every developer may have an in-depth understanding of these core components, which may lead to anomalies in your app that may even go undetected for a long time.
Companies which Android development services work with these components and have experience in enhancing the app development process while keeping these core components in mind, which is why it is beneficial to have an experienced company by your side.
Android Runtime (ART)
The Android Runtime (ART) is the runtime for all applications and services on Android. It uses ahead-of-time (AOT) compilation to improve performance, reduce battery usage, and provide greater flexibility in executing code.
ART provides a more efficient implementation of Dalvik that includes many improvements over Dalvik's original design, including increased memory footprint, reduced startup time and better handling of apps that use multiple CPU cores or cores with different clock speeds.
Android System Apps
The Android System Apps are the core applications that come pre-installed on Android devices. They're also known as pre-installed system apps, or "system bundles" for short. These apps can be divided into System Services and System Applications.
System Services are applications running in the background and provide basic functionality such as network connectivity, power management, location services, etc.
For example, these applications might include Fingerprint Authentication Service (FAS), which enables you to log into your phone with just one touch, or Network Location Provider (NLP), which helps determine where you are based on GPS data from your phone's location service provider (LSP).
System Applications are those additional apps that may not need to be installed by default but do require some form of root access—such as Google Play Store—to function properly; they often have their own unique feature sets as well!
The Linux kernel is the central component of Android. It's the core of your phone's operating system, which runs all of your applications and ensures they work together.
The Linux kernel is a monolithic operating system kernel that consists of thousands of lines of code written by thousands of developers over many years.
It's not possible for any single developer to know everything about it or even understand all its intricacies—so sometimes you'll hear about "themes" (or themes) being added to or removed from this huge collection of code.
Native Android Libraries
Native Android libraries are written in C++ and Java, and they are not part of the Android framework. The native libraries include hardware drivers, which allow apps to communicate with hardware components such as sensors or cameras.
These drivers are used for performance-critical code, such as handling audio data or processing video frames. Native libraries can also be used by other pieces of software that require access to these devices (e.g., games).
According to the companies which provide android development services, the drawback of using native libraries is that they are not available to apps; instead, developers must write their own code directly from scratch when implementing new functionality on top of them—a process known as "porting" or "porting over."
There you have a list of five core components of the Andriod platform, which play a crucial role in app development.
Last but not least, Android is a great platform for building applications.
It offers a number of features that make it easy to develop and deploy apps, from the use of XML classes to Google Play's restrictions on what can be added to an APK file.
