Architecture of Android
The architecture of an Android Operating System comprises a stack of software components which is separated into different sections and layers.
The Android OS uses the Linux kernel and it supports an extensive range of hardware drivers. It is the heart of the Android that controls the input and output requests from the software. This offers basic functionalities of a system like device management, memory and process management, such as camera, keypad, display, etc. The Linux kernel is good at networking and does not interface to the minor hardware.The Linux itself does not connect directly with the user, but rather networks with the shell and new programs as well as with the hardware devices on the system.
There is a set of libraries on top of a kernel, comprising of an open source web browser like webkit, library libc.These libraries are mainly used to play audio and record videos. The database SQLite is used to store and share application data. The SSL library is responsible for internet security.
The runtime of an Android OS provides a key component, namely DVM (Dalvik Virtual Machine) which is a type of Java virtual machine. It is designed and optimized especially for an Android. The processing virtual machine in Android OS is Dalvik VM. It is a kind of software that runs different apps on Android devices. This virtual machine makes use of kernel’s core features like multi threading and memory management, which are in Java language. This enables every Android application to run its own process. This VM process the files in the format of .dex.
Android comes with an online software store. It allows Android users to choose and download different applications developed by developers and utilize them. There are a number of games, and widgets available in the market for users. The applications of an Android are written in the Java language
