The USB Debugging and Developer Options are hidden in latest Android 4.2 Jelly Bean. If we want to use that options, manually activate it. Google has rolled out latest Jelly Bean OTA update for their nexus mobiles. After the updating process, the developer option is not there in settings. Here is the guide to enable USB debugging on Android 4.2 Jelly Bean running mobiles and tablets. Developer Options have many features for app developer to test an app on their device from PC via ADB.

Classes are the building blocks of your java application. If these blocks are not strong, your building (i.e. application) is going to face the tough time in future. This essentially means that not so well-written can lead to very difficult situations when the application scope goes up or application faces certain design issues either in production or maintenance. On the other hand, set of well designed and written classes can speed up the coding process by leaps and bounds, while reducing the number of bugs in comparison. In this post, I will list down 5 most recommended design principles, you should keep in mind, while writing your classes. These design principles are called SOLID, in short. They also form the best practices to be followed for designing your application classes. Single Responsibility Principle Open Closed Principle Liskov’s Substitution Principle Interface Segregation Principle Dependency Inversion Principle Lets drill down all of them one by ...

Is the allure of being a superuser tempting you?  Android  rooting opens up a world of possibility, but it can also void your warranty, or even leave you with a bricked device. The important thing is to be careful. Read up about what you are going to do before you begin. Make sure that you backup your data. Follow the instructions to the letter. Manufacturers and carriers have a vested interest in dissuading you from rooting. If you’re careful, the risk is minimal, and the potential benefits are impressive. Let’s take a closer look. What is rooting? If you’re an Administrator on a  Windows  machine, you have access to the entire operating system and you can do whatever you like. That’s essentially what happens if you root your Android device. With root access, you can get around any restrictions that your manufacturer or carrier may have applied. You can run more apps; you can customize your device to a greater degree; and you can potentially speed it up ...

Looking to cut out the background from an image, but aren’t quite sure how to do it? Well, no matter if you have Photoshop or not, you’ve come to the right place. In this article we’ll cover two different methods that will get the job done: one that uses Photoshop, and one that relies on a browser-based  Web  app. We’ll start with the simplest option – the Web app. Even if you’re partial to full-featured programs like Photoshop or GIMP, we highly recommend checking out Clipping Magic. We like it because the learning curve is insanely low, it doesn’t require any downloads or installs because it runs in your browser, and it doesn’t cost a single cent. The program is currently in alpha, but it still works like a charm. Here’s a quick rundown of how to use it:  If you’re fortunate enough to have a copy of Photoshop and prefer to use that,  we’ve also included a quick tutorial for that on page two.  1. How to remove backgrounds with Clipping ...

It seems like these days you can learn just about anything online for free, but of course some of that information is better than others. The good news is there are plenty of reputable places to educate yourself online for free, and here’s a TechProceed.com's compiled list of 20 of them to get you started. 1. Coursera The coolest thing about Internet learning is that you can take college courses which in the past were only available to people who forked over immense sums of money to attend elite colleges.  Coursera  brings a bunch of those classes together into one site, offering nearly 400 courses ranging from Introduction to Guitar from Berklee College of Music to Constitutional Law from Yale. Courses typically include videos and certain coursework (such as online quizzes) that must be completed in a certain amount of time, as these courses are monitored by a professor. Stop by regularly to see what’s new, or search for topics that interest you can put them on a watc...

"Cannot delete file: Access is denied" "There has been a sharing violation" "The source or destination file may be in use" "The file is in use by another program or user". "Make sure the disk is not full or write-protected and that the file is not currently in use" One of the best ways to handle locked files or folders is to use the free Microsoft program Process Explorer.
