According to the StatCounter statistics, the number of mobile web users has surpassed the number of desktop web users. This goes to show how many people use their mobile devices to browse the internet. According to Gartner prediction, the revenues from mobile app will surge to $77 billion in 2017. The question remains, how will you make your app stand out from millions of other mobile apps? The answer is by following the best mobile app development practices. In this article, you will learn about seven best mobile app development practices.
Know Your Target Audience
The first question that you need to ask yourself is who will use this app? Understand how your user will interact with your app and which feature they want in your app. If you want your mobile app to be a roaring success then you should know your audience like a palm of your hands. The better you know your audience, the better change you have to give them what they are looking for. Not only does this makes your job a whole lot easier but it also pave the way for delivering a perfect user experience for your app users.
Have a Design Strategy
Having a design strategy is critical for success especially when you are developing a cross platform mobile application. When you are designing a cross platform app, multiple activities are underway simultaneously. Therefore, if you do not have a sound strategy then there are bright chances that you mess up your mobile app. List down key functionality of your mobile app as well as future components on paper so that you can easily minimize the risk of emerging problems at different stages of app development cycle. Involving users into the design process will provide you with valuable feedback that will take you closer to designing a perfect mobile app for your users.
Develop Most Important Features First
Many app developers take the adventurous route of creating the most difficult feature of the app first. As a result, they fail to launch the app before the deadline and their mobile app exceeds budget. The best way to go about it is to focus on essential and core features and develop them first then move on to create features that are more complex. You will have to lay a solid foundation with core features and then take it from there. App developers can work on additional features and launch them in next releases or as a plug in when necessary but should focus on critical features of an app.
Make App Security Your Priority
According to Now Secure mobile security report, 35% of mobile communication, both voice and data are not encrypted. Moreover, most of the mobile communication takes place through wireless medium. This makes it a soft target for hackers and more vulnerable than other wired communication devices. Make mobile app security your priority, identify and fix any vulnerability in your mobile app before releasing the mobile app for users. Keep the user confidential and private information safe so that users are comfortable in using your mobile app.
Test, Test, Test
Despite putting a lot of emphasis on testing the mobile app before putting it up for downloads, a survey revealed that, less than 50% of companies test their mobile app for security while 33% do not even bother to test their mobile app, which is quite alarming. It is better to test your mobile app at each stage of the app development cycle but if you cannot do it, at least test the app thoroughly at the end and make sure that there are no glitches left before uploading your mobile application on app store. One bad user experience can prove to be very costly so it is better to pass your mobile app through comprehensive testing processes to prevent such issues.
Establish a Feedback Mechanism
Last but certainly not the least, is to incorporate feedback into your mobile application. Provide user with a medium through which they can give their feedback and share their opinion with you. Users can prove to be a vital resource if you allow them to give feedback as they experience crashes, bugs and errors that you might have missed. This makes it easy for app developers to make improvements in the future. Ask users about which features they want to see and add them in the future releases to satisfy them.
At the end of the day, it usually comes down to the user experience and satisfaction that will decide the fate of your app. If you know about any other mobile app development best practice that can make a big difference to your mobile app development efforts, then feel free to share it with us in comments section below.
A web camera is absolutely necessary when connecting with friends via video call software like Skype or Google hangouts. But when the built-in webcam is your laptop has stopped working, what would you do? Send it to computer repair store or buy a new external computer camera? Actually the repair cost may be higher than a new external camera. And If you require high quality video call, it’s better to have a USB camera. You have many choices of a good desktop webcam. What you should do to change built-in webcam to external computer camera?
Disable Internal Webcam
Disable the internal webcam through Windows. Click in the top right-hand corner of Windows and select the "Search" charm, then type "device manager." Click on "Device Manager" under "Control Panel" to launch Device Manager. Expand the section beside "Imaging Devices" and then right-click on your webcam and choose “Disable”. After these process, your computer program like Skype is able to recognize your new pc camera.
A development team, working on a static analyzer, has already checked a game engine under Windows. In this check we used a Linux version and the result showed that there were a large number of serious errors. The article covers only the general analysis warnings and only “High” level of severity (there are also Medium and Low levels).
We can say that mobile and tablet applications have replaced the TV because in the research, it is found that people today spend minimum three hours every day on their mobile devices. Android development India team experts are leaving no room for bugs in such applications that could disturb the audience while watching their shows. More entertainment applications are coming with their own web series and movies and thus, people spend lesser time on TV nowadays.
The days are gone when we called television the “first screen” for entertainment. Lots of entertaining applications are now made by android developers and the idiot box has been replaced by phones and tablets officially as the trend is on rise for the past two years.
In this article we'll look at the main features of SonarQube - a platform for continuous analysis and measurement of code quality, and we'll also discuss advantages of the methods for code quality evaluation based on the SonarQube metrics.
SonarQube is an open source platform, designed for continuous analysis and measurement of code quality. SonarQube provides the following capabilities:
One of the main problems with C++ is having a huge number of constructions whose behavior is undefined, or is just unexpected for a programmer. We often come across them when using our static analyzer on various projects. But, as we all know, the best thing is to detect errors at the compilation stage. Let's see which techniques in modern C++ help writing not only simple and clear code, but make it safer and more reliable.
What is Modern C++?
The term Modern C++ became very popular after the release of C++11. What does it mean? First of all, Modern C++ is a set of patterns and idioms that are designed to eliminate the downsides of good old "C with classes", that so many C++ programmers are used to, especially if they started programming in C. C++11 looks way more concise and understandable, which is very important.
Technology: Querydsl is a java based framework which enables the construction of statically typed SQL-like queries. Instead of writing queries as inline strings or externalizing them into XML files they can be constructed via a fluent API like Querydsl.we can use Querydsl in java application for creating all kinds of sql statements.Querydsl has various plugins for JPA,mongoDb, SQL,lucene and also for java collections.
The development team working on PVS-Studio has finally started developing its product for Linux. That was the news that the CTO Andrey Karpov wrote about in the article. Long disputes and requests of the readers on habrahabr.ru, discussions on Reddit, Linux.org and other places can now gain a new round of comments. As it is mentioned in the article, you can volunteer to help the developers to test this product and improve it to a better level.
There are many tasks on the way of PVS-Studio to Linux, that the technical director is talking about. Put briefly, these are:
- more complete support of GCC and Clang;
- a new system of regression tests in Linux, so that you can track the changes results in the analyzer kernel and add new diagnostics;
- compiler monitoring to help programmers quickly and easily check the project without distracting people who support makefiles and the build system in general;
- documentation improvement, so that the user can get information with the examples about any diagnostic;
- testing, distribution, support organization.
In this article you will find more details about the abilities of PVS-Studio for Windows and the tasks it can already solve on Linux.
Often people ask questions - which programming language is easier, which is the most popular, which one to start learning and so on. In this article we will compare two languages Python and Ruby; their reference implementations CPython and MRI, to be exact.
We took the latest versions of the source code from the repositories (Ruby, Python) for the analysis. There weren’t many glaring errors in these projects. Most of them are related to the usage of macros, although this code is quite innocent from the point of view of the developer. But at the same time, such suspicious fragments that occurred because of copy paste, comparing SOCKET type with null, undefined behavior, storing values to the variables that are already used or null pointer dereferencing are really worth reviewing.
Having analyzed all the warnings of general analysis diagnostics and removed all the false positives, we have come to the following conclusion concerning the error density:
More details about the code fragments where these suspicious code fragments were found:
It’s worth saying that despite these flaws, the code is still of high quality. We should also take such factors into account as the size of the codebase , or the fact that some fragments are erroneous only from the point of view of C++ language and they don’t affect the program in any way. That’s why this analysis may be rather subjective, because previously we haven’t evaluated the error density of these projects. We’ll try to do that in the future, so that we can later compare the result of the checks.
Nowadays a lot of projects are opening their source code and letting those who are interested in the development of it edit the code. OpenJDK is no exception, programmers PVS-Studio have found a lot of interesting errors that are worth paying attention to.
OpenJDK (Open Java Development Kit) - a project for the creation and implementation of Java (Java SE) platform, which is now free and open source. The project was started in 2006, by the Sun company. The project uses multiple languages- C, C++, and Java. We are interested in the source code written in C and C++. Let's take the 9th version of OpenJDK. The code of this implementation of Java platform is available at the Mercurial repository.
During verification, the analyzer found different errors in the project including: copy-paste, bugs in the operation precedence, errors in logical expressions and in pointer handling and other bugs, which are described in detail in this article.
It's always amusing to check a project which is used and maintained by a large number of people. The better and more accurate the code is, the more safely and effectively the program will work. Those bugs we found, are another proof of the usefulness of an analyzer, as it allows the detection of such errors which would otherwise be hard to detect doing simple code review.
