Some Distinctions Between Android And J2ME

A certain set of several software products and specifications is known as Java. Developed by the Sun Microsystems (now a part of Oracle Corporation), Java provides a system application development software that can be deployed over various cross platform computing environment. The software product is utilized on a number of computing platforms from mobiles to embedded devices, to the enterprise servers and supercomputers. The Java applets are used to provide security when browsing the internet.

Writing of the language produces code as Java bytecode. Though there are compilers for languages like JavaScript, Python, Ruby and Ada, the new language is designed to run locally on the Java Virtual Machine (JVM) named Groovy, Clojure, and Scala. The syntax borrows heavily from C++ and C. With a simple memory model, all objects are heaped and the variable object types are referred. The memory management is processed by JVM’s automated garbage collection.

The language of Java has undergone many changes since the launch of Java Development Kit 1.0 in January 23, 1996. After the J2SE 1.4, the Java Community Process (JVM) primarily governed this language.

The Java Platform, Micro Edition

The Java ME language is a platform devised for embedded systems, like devices such as a mobile phone to industrial objects to set top boxes. Designed by the Sun Microsystems, the platform was the replacement of Personal Java, a similar technology. Developed under the JCR as the JSR 68, as per December 22, 2006 the J2ME is licensed under the GNU General Public License.

Distinction between J2ME and Android

Both Android and J2ME are used to create mobile applications. The following are some of the key differences between the J2ME Applications and Android Software Applications:

The Android mobile devices come with more functionality than J2ME. Equipped with camera and GPS, the Android can be configured to incarcerate data using customized code of third parties. This enables integration of novel data. J2ME can perform similar multimedia playback and GPS collection, but it makes the phone more expensive. GPS and J2ME need a S60 operating system which is more complex.

The Android mobiles are built integrating user interface allowing easier working interface and enabling easier navigation. Much more intuitive than J2ME, the problem lies in mistaken entries or accidental exits from the application. On the other hand, J2ME interface is limited but streamlined and can take over entire functionality of the device.

The display screen of the Android is much bigger for easy accessing. The J2ME apps are optimized for better visibility albeit in a much smaller screen. This makes sharing of videos and images difficult. However, in Android, the viewing angles can be resistive.

Android with low-technical capacities have been using ODK in the past but many components were difficult to adopt. The widgets were more visible and easier to use. J2ME supports “sense” mode. This is designed for users with low technical capacity. Familiar with those who use the S40 Smartphone are often frustrated with the inefficiency of sense interface.

The Android apps require fewer configurations and have automatic updates. With the highest turnover this year, the Android was the preferential choice for most users. J2ME requires manual configurations that are deleted once the battery runs out. Although, the phones have improved local support, but there has always been complaints of fraudulences.

The Android already have specific external features deployed in the device that the user can take advantage of. The J2ME is inconspicuous, though there is an extensive range that is available in the market.

Your Android Smartphone May Be Leaking Personal Data

Smartphones had changed the way we communicate, get information, and entertain ourselves. With smartphones increasingly becoming low-priced and within the range of the average person, therefore, it is no surprise about the source of their widespread success around the globe is their low- price and computing capabilities. With Apple’s iPhone a bit on the pricey side, Google’s Android based Smart-phones are the choice of smart-phones loving frugal folks. Moreover, with multiple manufacturers of Android based smart-phones such as HTC, Samsung, Sony, Huawei, Motorola and LG, the choices of Android based smart-phones are endless. Consequently, such variety and affordability has propelled Google’s android based operating system as the iPhone’s impossible-to-knock-out adversary. Therefore, it’s a given fact that Android operating systems for smart-phones are the entire buzz these days.

Yet, recently, Android has once again made negative headlines, this time on the subject of personal data. Security researchers at Leibniz University in Hanover, Germany found that some perfectly legitimate android applications available for download on Google ‘Play’ may leak your data to hackers. Even so, the team didn’t come across any reported incidents that reported any hackers have taken advantage of this loop-hole.

To be more specific on how confidential data can be leaked with these applications, researchers have found that almost all android applications used SSL and TLS security protocols to transmit your private data. Shockingly, what the research found was that these security protocols weren’t designed properly in these apps – they were faulty. Therefore, if you have recently downloaded apps from Google Play, chances are your username, passwords, credit card number and addresses could be leaked. To test our data leak vulnerabilities, a tool known as ‘MalloDriod’ was used, which can detect Man-in-the-middle attacks.

What researchers determined was that 8% of the applications were defenseless against MITM attacks. The way it works, is that a third-party – hacker, connects between two devices, seemingly acting as a communication device using advanced hacking application. Researchers determined that any application that sends out a certificate is open to attack. What shocked researchers the most, was that 41 out of 100 applications contained this security loophole.

It’s estimated that anywhere from 40 to 185 million users may have downloaded such apps. Researchers say that better security measures and regulations installed within Android operating system is the key to keeping data safe. The majority of the applications available on the ‘Play’ store are not mandated to have strict security protocols, implementing foolproof security measures in Android compatible applications should be the responsibility of the developer of that specific application. It’s up to Google to enforce compliance to protect its user’s identity.

On a different note, smart phones are not the only culprit that can leak personal data. The widespread use of portable-data-storage-devices such as thumb drives and portable hard-drives can also contribute to data theft. If you end up losing one of these devices, and by mistake you happen to have your intimate data stored on them, such as e-statements, tax return or copies of private identification, then there’s potential for some trouble. Experts recommend that when transporting sensitive data on transportable drives, it’s highly recommended that you secure USB movable drives and hard-drives with portable data security software. Identity theft is hot business for criminals, as it is considered an easy way to steal information without ever getting caught. What’s really worrisome is that, by the time you come to know that your data has been stolen, it may be too late. It’s likely that the criminals may have already charged up your account, and you may only find out about this charge once you receive your credit card bill.

Rise of Androids For Mobile Application Development

Android is a Google’s product. It’s a free, open source mobile operating system. It includes a software development kit, libraries and tools which eventually help to create third party applications using the Java framework. Though it is spreading among mobile users rapidly, apple’s iphone is unbeatable in market share.

In order to popularize their product, Google has been looking for android developers who can bring a lot of innovation and creativity to this platform. Recently it has launched android developers challenge to incorporate new ideas and technology into androids.

Symbian, Windows Mobile, Palm and OS X for iPhone are some of the popular operating system today. Most of them are closed systems. To compete all these mobile platform, Google android uses open network concepts. Thus android users can develop application that suits their needs in a more user-friendly way.

Activities, broadcast receiver, services and content provider are the fundamental concepts in androids mobile application development. Android developers who work on these concepts have good growth and scope today. Though Google hopes that androids will be the leading mobile platform soon, apple’s iPhone is people’s choice today as it well supports third party applications.

Now-a-days mobile users opt for phones with more features, functionality and options. To meet their demands, developers now look for androids mobile development. Android applications have been developed in many software companies. Many offshore consulting offer cost-effective solutions to android development.

May be now, android is not a leader for mobile platform, but it will lead the world market soon as Google has taken vigorous steps like forming Google android alliance and offering incentives to enhance its development.
