Introduction
To first introduce the topic, Android is an incredibly popular mobile operating system. In recent years it has gained a huge following and a person can find Android enabled phones and tablets everywhere. According to Kerr (2013), as of November 2013 Android devices are currently dominating the smart phone market at about 80% of all smart phones being an Android device. Personally, I currently use a Droid Razr which is outfitted with Android Jelly Bean (Android 4.1), which is not the newest Android release, but it is among the most popular at this time. I also previously owned a Droid 1, which is what really put me on the Android path. While my usage of Android products doesn’t account for much market share, I am still a firm believer in Android, and the numbers really show that many more people are similarly minded. As Android’s popularity increasingly grows though, it comes to a point where to be effective as a programmer in a mobile market; you have to learn the Android ropes. The ropes for Android programming start in Java programming, which makes the transition quite easy for most programmers as Java is still a very popular language. This brings up a few questions though. Now that I know where to start, where is this path going to go and how is it different than normal Java? Are there many challenges in this transition from JRE to Android?
Java Programming Introduction
Java itself is a very powerful and flexible programming language. It has many features which make it a fantastic choice for programming. Some of the features include, but are not limited to:
1. Portability – the code is compiled and run in a specific environment, not an operating system
2. No pointer arithmetic
3. Garbage collection...

...ster based processing requires fewer instructions, but the tradeoff is that these register instructions must be longer. The benefit from using register based processing is the fact that Android applications need less memory to execute efficiently. This is especially useful due to the compressed environment it must work with.
It is highly useful to learn the specifics of programming in standard Java and where it compares to Android based Java. This is especially true if a programmer wants to delve into the mobile world. Realistically it would not be a difficult transition either, learning to program Android applications would essentially be an extension to learning Java. The only reason I bring it up to learn Android was also stated in the introduction. Android is an incredibly popular mobile operating system. Not only that, but it is incredibly successful.
Apps are somewhat hard to make because of software differences, they have a simpler code, which creates less time to make. The products that the software covers are also apart of their credibility as a brand. iOS covers the product line of apple which includes Macbooks, iPads, iPhones, and iWatch. While android covers a larger base of products, they lack the software reliability from their users of product. Samsung is a great example of this problem with recent blowing up of their products, which doesn 't only affect their brand name but also the software that backs up the product.
The programs where you create this code are called compilers. These things act as the converters between the programming you write and the machine language the computer
Programming languages are classified by its programming paradigms these can be either procedural, object oriented or event driven. However some programming languages can support more than one programming paradigm, java is a good example of it as it supports both procedural and object oriented programming.
This definition includes all views of the source code and covers the parts of algorithm animation, which includes object (i.e. variable values, object states) visualisation and source code visualisation that can be static (compile time) in nature or dynamic (run time) in nature. Some applications of Java source code visualization contains debugging the source code, evaluating and improving program implementation, flow of algorithms, understanding program behaviour and teaching.
Apple and Samsung are the two most important technological companies in the mobile phone market. Both companies have achieved outstanding sales in the past years and have made some competitors such as Nokia or Blackberry almost inexistent. This does, therefore, raise the question: Apple or Samsung? Which one will win the technological battle? Both enterprises have been challenging each other in the past few years in order to win this smartphone war. Research and analysis of the company’s sales, show that both companies focus over 50 per cent of their production on the global smartphone market. Samsung is a perfect example. The company has managed to produce low cost high quality smartphone products attracting new customers and, therefore, expanding the company’s market shares. Its net profit also rose to 8.24 trillion between the months July and September of 2012 (Jones 1). The success and peculiarity of its new low cost high quality products as well as its emphasis on innovation has allowed Samsung to find a way to win this technological battle.
It is intended to let application developers "write once, run anywhere" (WORA), meaning that compiled Java code can run on all platforms that support Java without the need for recompilation. Java applications are typically compiled to bytecode that can run on any Java virtual machine (JVM) regardless of computer architecture. As of 2015, Java is one of the most popular programming languages in use, particularly for client-server web applications, with a reported 9 million developers. Java was originally developed by James Gosling at Sun Microsystems (which has since been acquired by Oracle Corporation) and released in 1995 as a core component of Sun Microsystems' Java platform. The language derives much of its syntax from C and C++, but it has fewer low-level facilities than either of
Most computer languages use different versions of compilers for different types of computers or operating systems; so one language may have different compilers for personal computers (PC) and Apple Macintosh computers. Many different manufacturers often produce versions of the same programming language, so compilers for a language may vary between manufacturers.
Many different types of programming languages are used to write programs for computers. The languages are called "codes". Some of the languages include C++, Visual Basic, Java, XML, Perl, HTML, and COBOL. Each of the languages differs from each other, and each is used for specific program jobs. HTML and JAVA are languages used to build web pages for the Internet. Perl and XML can produce codes that block students from getting on certain inappropriate web pages on their school server. One of the most prominent programming languages of the day would have to be C++.
Along with different brands, as you can imagine, there are an abundance of models too. So whatever you may desire in a phone, there are many different options to choose from when selecting an Android phone. As I stated earlier, the Google Play Store does not have many limitations on apps. This allows companies and individuals to upload and create their own apps, causing there to be more apps available to Android users. Not only are there more apps, the selection is much more broad and a desirable type of application may come in different forms over the Google Play Store.
XML can be used with a large assortment of other languages and is not specific to any one operating system or vendor. It is text based and Unicode compliant and can be translated into the many commonly used written languages (Walsh, 2003). This allows for more businesses that run a variety of platforms and operate internationally to take advantage of this technology.
Despite the short amount of time since the introduction of the smartphone, the rapid development of the software and technology has had a tremendous effect on the everyday life in society today. The concept of communicating through a telephone was developed in the 1870s. Devices to transmit speech electrically were designed by Elisha Gray and Alexander Graham Bell, but Bell's design was patented first. On March 10, 1876, Alexander Graham Bell achieved one of his greatest successes in the making of the telephone. This brought upon a major change in communication and gave leeway to the improvement of the telephone in the days to come (Bellis, 2013b). During the 20th century there were many innovations regarding the telephone. In 1973, the first call from a portable phone was made Martin Cooper, who was a Motorola researcher and executive at the time. Since its inception, the advancement of cell phones has been exponential (Bellis, 2013a). As a result, cell phones have changed how society works in today's world. Many people lack the insight of how cell phones, or in this case, smart phones, affect the people that use them. So the question is, how is the evolution of smart phones impacting our society?
Traditionally, one program is written and execute on a single computer and on a single processor. But it can take more time to solve a problem if it is large enough.
Computer programming can as well be defined as a process that leads from an original formulation of a computer problem to execute problems. Computer programming is also referred to as programming. It encompasses other activities such as understanding, analysis and generally solving problems that result in algorithm, verifying the algorithm requirements and coding algorithm in a target program language. The program also involves the implementation of the build system and managing derived artifacts like computer programs machine codes. Most often, the algorithm is represented in human-parseable languages such as Java, Python, Smalltalk among others.
Mobile application is a very aggressive market, there are hundreds of platforms to choose from when designing applications. There are several platforms that currently dominate over other platforms. The Android platform is very popular, it’s one of the most preferred platforms for building applications. Most of its applications are built using JAVA software, but there are others software that are just as equal or greater. Java software is free and offer a free software development kit. The kit consists of sample applications, source codes, developer tools, and emulators...
Global smartphone shipments will reach 567 million units this year alone (2012). And by 2016, 1 billion people worldwide will own smartphones,” (life hacker: 2012).
