The application is developed to work on Android operating system. Front end logic for the presentation layer is developed using Android Studio SDK. The source components in the project build includes different Java files for activities and utilities; XML files for manifest, layout and values; resource files for background images, icons and product images.

Android and iOS devices are the most seen on the market. Both offer different qualities and it depends on the users’ preference.

There are numerous advancements in technology since past few years especially in Mobile technology. A great evolution has also been done in operating systems as well. Different Mobile operating systems are available in the market for smartphones which includes Android, IOS, Windows mobile, Blueberry OS, Symbian OS and many more. The most popular among all are Apple IOS but the newest and popular as well is Android. It doesnot only contains Operating system but also middle ware and key applications. It is the First Open Source Operating system. The OS of android is based on Linux Kernel and it was developed by OHA (Open Handset Alliance). An abstraction layer is provided by Linux kernel between Hardware and the rest Stack. Furthermore, Android SDK also gives the necessary APIs and tools in order to develop android applications using the java programming language. Special user interfaces of android exist like Android TV that for television channels, Android wear for wrist watches and Android Auto for cars.

Android is a software stack for mobile devices that includes an operating system, middleware and key applications. Android is a software platform and operating system for mobile devices based on the Linux operating system and developed by Google and the Open Handset Alliance. It allows developers to write managed code in a Java-like language that utilizes Google-developed Java libraries, but does not support programs developed in native code.

IBM’s Simon Personal Communicator, introduced in 1994, despite not being the first smartphone, was the first device to feature a phone with additional capabilities to act like a personal digital assistant, which would pave the way for future development of the mobile phone industry. It has come a long way from the first Blackberry 5810 in 1999, to the Motorola RAZR in 2004, and eventually the iPhone and Android in 2007 and 2008 respectively, which ushered in the new age of smartphones.

I will start by mentioning the pros of Android OS. Android 8.0, according to benchmarks tests, runs two times faster than the previous Android OS (7.0 Nougat). This is a plus for me because I am frequently using gaming and social media apps. The Android OS is open sourced, which grants me the ability to download 3rd party apps. Because of this, and because I love listening to music, I can get Spotify Premium and Pandora One for free by downloading the apps from internet websites rather than from the Play Store. Another benefit of the Android OS is the new Picture-in-Picture mode that comes standard with the Android 8.0 upgrade. This mode allows videos to be shrunk down to a resizable window allowing the user to open and operate other apps. Personally, I do not think I will use this mode a lot, but it is nice to know that I can use it whenever I please. While Android’s OS has many benefits, the same OS also has many setbacks.

Although app developers build mobile apps for purchase convenience, they have become more of marketing tools. So, even app developers now include different functions to aid marketing in Android and iPhone app development.

Android is an operating system that was built upon the very popular Linux kernel. Its main focus has always been that of providing one of the best options for an operating system that will work for touchscreen devices. Those devices typically include various smart phones as well as what has been a newer craze as of late, tablets. Android was originally a self-operated company, however it was eventually bought out by Google, who was its greatest financial support. Linux itself is a very old operating system that was built on the platform of being free for everyone, as well as being open sourced so that anyone could have the opportunity to customize it to their liking to provide different functionalities that the particular user may need. The popularity of Linux exploded and with that and its ability for customization it has become of the most secure operating systems there is. This provided an obvious choice for it to become the core of the Android system, thus providing tremendous security for anyone that uses an Android operated device. The main features that were chosen from the Linux kernel to become assets in the Android operating system were as follows; user based permission, the ability to isolate processes, the ability to remove certain parts of the kernel that could have the potential to be insecure, and a very secure inter-processing structure for communication among various parts of the operating system.

Applications: These are applications written in Java. Some of basic applications include a calendar, email client, SMS program, maps, making phone calls, accessing the Web browser, accessing your contacts list and others.

While everyone desires to have a piece of the digital pie emanating from the thriving app industry, not every prospective and professional mobile app developer and Android application development company is armed with the real facts of the development process.

When Android was launched it was primarily a mobile operating system based on a Linux kernel developed and backed financially by Google. The plainness of user interface played a momentous role in spreading the use of Android. The end user could manipulate the on - screen objects by real - world actions such as swiping, tapping, pinching and many other actions to make Android an compliant platform. Its main use was seen mainly in smartphones. With the growth of time, Android found its way in tablet computers, television, cars and wrists watch. These were some of the characteristics that in my idea led to use of Android in gaming consoles, camera and other electronics.

With every passing day new innovations are being brought into the field if information technology. Things that have been old enough are always upgraded and renewed in order to make their use even more effective in use. The technology of android which has been introduced by the organization of Google has made life for all the smart phone users entertaining and easy at the same time. The applications brought forward by the different application developers are not only entertaining but are proven useful in many other aspects. Everything about a smart phone is enjoyable and entertaining. People have become bad addicts of the applications offered in the Google Play Store. The real life like gaming has provided an extra ordinary experience to all the users of smart phones ad tablet devices. But the only thing about an android device which holds it strengths is its small screen. How about having all the entertainment and fun on the large bigger and wider screens of laptops and personal computers? It is the basic reason of improvising the technique of android into something even more mind blowing then what it already is. Droid4x has made it possible to get all the excitement and fun on your personal computers and desktops. As it is a virtual machine it seems as if a whole android device is incorporated into the system of the personal

Google 's Android is the most popular mobile platform in the world with more than eighty percent market share, and it is based on JAVA which was developed by Sun Microsystems and currently own by Oracle. JAVA is an open source language and open to the public to use for free. However, open source code does not allow modifying the code without licensing or publishing back the modified code in the open community. In 2007, when Google first released Android SDK beta, they have used some of the JAVA higher level interfaces that require licensing. Google knew that from the very beginning, modification of JAVA code and including them in the Android SDK is violating copyrights law yet they went on using the modified JAVA

The Android Software Development kit (SDK) is inclusive of a set of development tools which further include a debugger, libraries, emulator, documentation, sample code and tutorials. Eclipse is the official supported integrated development environment and it uses ADT plugin. The android applications are saved in .apk file
