The Architectural Design of Android
If we talk about the architectural structure of the Android software, then we can say that it is well building software. It has a stack of software components which are further divided into the five sections and four layers – Linux kernel, libraries, and Android runtime. All these components are explained ahead –
Android uses the highly technical Linux kernel to support its wide range of hardware drivers. You can say that kernel is the heart of the operating system which is handling input and output requests. The basic functions of the kernel are to process features like process management, memory management, devices like cameras, display, etc., In short, the kernel handles everything in the android. Linux is a very good networking software and it doesn’t require a necessary interface for the peripheral hardware. The kernel won’t directly interact with the user here, but it interacts with the shell and other programs with hardware devices on the system.
On the top Linux kernel, you will find a set of libraries on the Android which includes source web browser such as WebKit, library libc. The libraries are used to play and record audio and videos. The SQLite is a database which is useful for storage and sharing of application data. The SSL libraries are responsible for internet security etc.
The Android runtime is another important part of the Android design which offers the component named Dalvik Virtual Machine that is a sort of java virtual machine. This virtual machine is specifically designed for the Android OS. It is a process machine in the Android operating system. This software enables other applications to run over the android devices. The Dalvik VM uses the Linux core features such as memory management and multithreading easy to use in the java language. It gives power to every Android application to run on its process.
Features of Android
The Android applications can be located on the top layer and you can easily write applications on this layer. The applications such as books, browsers, services, etc., can be created on Android. Every application performs a different role in the overall applications. The features performed by applications are –
- Headset layout
- Language support
- Visual calling
- Screen capture
- Media support
- Optimizing graphics
What is Android Emulator?
It is a new application of the android operating system family. The emulator is a new system which is used to develop and test Android applications without the support of any physical devices. It got all the hardware and software features such as mobile devices but it doesn’t support phone calls. It also offers multiple navigations and control keys and helps in displaying your application. It is designed to utilize the Android virtual device configuration. Once you have your application running over it, you can use the service of the android platform to assist other apps, access the network and play video, audio and much more.
