What is Android

                        Android is a mobile operating system developed by Google. It is based off of a modified version of the Linux kernel and other open source software, and is designed primarily for touchscreen mobile devices such as smartphones and tablets

How does it work?

                      Beginning at the base is the Linux Kernel. Android utilizes Linux for its gadget drivers, memory the board, process the executives, and systems administration. ... The following level up contains the Android local libraries. They are altogether written in C/C++ inside, however you'll be calling them through Java interfaces.

Purpose of Android

                      Android (working framework) Android is a portable working framework created by Google. It depends on an altered variant of the Linux piece and other open source programming, and is structured fundamentally for touchscreen cell phones, for example, cell phones and tablets.Android is a portable working framework kept up by Google, and is every other person's response to the prevalent iOS telephones from Apple. It is utilized on a scope of cell phones and tablets including those made by Google, Samsung, LG, Sony, HPC, Huawei, Xiaomi, Acer and Motorola.

Android better than iOS:

                              Most Android phones do betterthan the iPhone released in the same period in hardware performance, but them hence can consume more power and need to charge once a day basically. Android's openness leads to increased risk.Gangboard Provided Best Android Online Training

You will be happy to realize that you can begin your Android application advancement on both of the accompanying working frameworks −

·         Microsoft Windows XP or later form.

·         Macintosh OS X 10.5.8 or later form with Intel chip.

·         Linux including GNU C Library 2.7 or later.

 

 

Second point is that all the expected apparatuses to create Android applications are openly accessible and can be downloaded from the Web. Following is the rundown of programming's you will require before you begin your Android application programming.

·         Java JDK5 or later form

·         Android Studio

Here last two segments are discretionary and on the off chance that you are taking a shot at Windows machine, at that point these segments make your life simple while doing Java based application advancement. So given us a chance to see how to continue to set required condition.

Android  Architecture

                             The Android OS is a product heap of various layers, in which each layer is a gathering of some program parts. It incorporates your working framework, middleware and significant applications. Each layer in the engineering gives various administrations to the layer simply above it.

Following are the various layers in the Android stack:

Linux Kernel Layer– Linux portion is the base most layer in the design of android. It never truly connects with the clients and designers, yet is at the core of the entire framework. Its significance originates from the way that it gives the capacities in the Android framework, for example, equipment deliberation, memory the executives programs, security settings, control the board programming, other equipment drivers, organize stack and so on.

Libraries– The following layer in the Android engineering incorporates libraries. Libraries convey a lot of guidelines to manage the gadget to deal with various kinds of information. For instance – the playback and recording of different sound and video arrangements is guided by the Media Framework Library.

Runtime – The third area of the design is runtime which gives a key segment called Dalvik Virtual Machine (DVM). Dalvik is an open-source programming and Java Virtual Machine uncommonly structured and enhanced for Android.

Application Framework Layer– Our applications straightforwardly associate with these squares of the Android engineering. These projects deal with the essential elements of telephone like asset the executives, voice call the board and so forth. It gives numerous higher-level administrations to applications as Java classes. Some significant squares of Application Framework are action the executives, content suppliers, asset director, warning supervisor, see framework.

 

Applications layer– The applications are at the highest layer of the Android stack. Every one of the applications will be introduced in this layer, for example, address book, games and so on.

Android Open source

                     Android is an open source and Linux-based working framework for cell phones, for example, cell phones and tablet PCs. Android was created by the Open Handset Alliance, driven by Google, and different organizations. This instructional exercise will encourage you fundamental Android programming and will likewise take you through some development ideas identified with Android application improvement.

Conclusion:

scope of Android

          The Mobile Application Development is the future of Software Development according to Google's Eric Schmidt. The numerous young students who are looking for a stable career with the steady growth and income, they always ask about the future in the software development, especially in the Android applications.
