TextWrangler has the advantage of being a free editor for your Mac. If you are used to developing using Objective-C, Xcode is a natural choice. When you open up your Corona SDK folder, you will find sample code, tools, a resource library as well as the Corona Terminal and Simulator the primary development tools that we will be using.
This was easily corrected by downloading newer graphics card drivers to the system. Corona SDK will run with older versions of OpenGL installed, as long as it is an application that is graphic intensive. You should be able to update your graphics card driver to correct the problem if it exists. This is a free download from the Oracle website. After you have downloaded the installer, follow the normal procedure to install the JDK to your system.
Complete this one time authentication and you will be ready to go. Corona Developer Registration You should always launch the Corona Debugger on a Macintosh instead of the Simulator for performing application builds and testing. On a Windows system, launching the Corona Simulator also launches the Corona Simulator Output window commonly referred to as the terminal window. The Corona Terminal gives you important feedback when you are building your apps and allows for easier troubleshooting.
The Corona Terminal will automatically launch the Corona Simulator. Project 1. I purchased the book or took the class because I wanted to program, not to go over some syllabus or a review of all the different ages of computer development. Stop with the rolling of eyes!
Before I lose you, let me guarantee that you will get a very valuable resource out of this Hello World project, something that you will use the rest of the time that you develop in Corona.

Look in the Terminal window. At the bottom you will see your Hello World displayed. Hello World in the Corona Terminal window Congratulations! You just made your first Corona app!
Now before you become disappointed, you just learned a very important tool for trouble shooting your applications. Believe me when I tell you that this one command will save you hours of troubleshooting headaches! The first few lines provide information about the version of Corona and the location of the simulation files. Try newtext and look at the error that appears in the Terminal window. Save the file, and then launch your simulator. You should now see Hello World displayed in the simulator.
We do not have to use the variable name textobj, we could use fred for the variable name but after a couple of days we might forget what fred represents. Use variable names that make sense. It might mean more typing, but you will really appreciate it when you go to revise or update the program at a later date. We set textobj equal to the object that we create by calling display. The display. If you set this parameter to nil, it will default to the native. I want to get you in the practice of setting the text color when you create a text object.
Later we will look at how to fade the text object out or in. Warning: If you copy code from a website or even from this book , sometimes the quotation marks will change from straight quotation marks to smart quotes. Objects You may have noticed the use of the term object sprinkled throughout the text thus far. Just as in the real, physical world, I can move or interact with an object a lamp, table, or car , an object in your software is anything that can be interacted with.
Summary This has been a busy chapter! Corona should now be installed on your system, you have been introduced to editors, hardware considerations, and publishing information. We even managed to develop two apps! The first introducing the critically important print command, the second actually displaying text to the simulator.
Finally, the concept of an object in programming was briefly introduced. Know your Boundaries When developing for multiple types of devices it is important to automate the placement of objects on the screen. In Corona, this can be done easily with display. This can easily be accomplished using the print command that was discussed in chapter 1. Start by creating new folder and name it Boundaries. Now create a main. Add the following code: print "Height: ", display.
Your terminal windows will show the results. As you can see in Figure 1, the height is pixels and width is pixels. Project 2: Button Fun For this project we are going to create an app that will move a text object to a random place on the screen each time the button is tapped. First we will create a folder and name it Button Fun and a empty main.
For this project you will need to create a button graphic. I used Photoshop or gimp, paint, or any other graphics software and created a small pixel by 50 pixel rectangle and saved it as button. Make sure you save it to the same folder as your main. To load the button. If you save the main. Try entering the following code after you create your myButton object and see the difference: myButton. We are able to move the myButton object anywhere on the screen we want. But there is a problem.
There are a lot of different types of devices that we can build for with Corona and each one has a different resolution. Fortunately this is easy with the commands we have already played with: display. Using a little simple math, we can place the myButton object in the exact center of the screen. Replace the original myButton. The button should now be in the exact center of your screen. For the next part of my project, I want text to be displayed when I press the button. To simplify the interface, I want the button at the bottom of the screen. Again, with a little math, this is easily accomplished.

Application software developers also must consider a long array of screen sizes, hardware specifications, and configurations because of intense competition in mobile software and changes within each of the platforms.
Mobile app development has been steadily growing, in revenues and jobs created. Mobile UI considers constraints, contexts, screen, input, and mobility as outlines for design. The user is often the focus of interaction with their device, and the interface entails components of both hardware and software. User input allows for the users to manipulate a system, and device's output allows the system to indicate the effects of the users' manipulation. Mobile UI design constraints include limited attention and form factors, such as a mobile device's screen size for a user's hand s.
Mobile UI contexts signal cues from user activity, such as location and scheduling that can be shown from user interactions within a mobile app. Overall, mobile UI design's goal is mainly for an understandable, user-friendly interface. The UI of mobile apps should: consider users' limited attention, minimize keystrokes, and be task-oriented with a minimum set of functions. Mobile UIs, or front-ends, rely on mobile back-ends to support access to enterprise systems.
The mobile back-end facilitates data routing, security, authentication, authorization, working off-line, and service orchestration. Notable tools are listed below. With a C -shared codebase, developers can use Xamarin tools to write native Android, iOS, and Windows apps with native user interfaces and share code across multiple platforms, including Windows and macOS. After Microsoft first announced their. Ximian was bought by Novell on August 4, , which was then acquired by Attachmate in April According to de Icaza, at least part of the original Mono team had moved to the new company.
The name Xamarin comes from the name of the Tamarin monkey, replacing the leading T with an X. This is in line with the naming theme used ever since Ximian was started. It was not known at that time how Xamarin would prove they had not illegally used technologies previously developed when they were employed by Novell for the same work. In February , Xamarin announced the release of Xamarin 2. The kit allows for the development of mobile apps on Apple's iOS operating system.
While originally developing iPhone prior to its unveiling in , Apple's then-CEO Steve Jobs did not intend to let third-party developers build native apps for iOS, instead directing them to make web applications for the Safari web browser. However, backlash from developers prompted the company to reconsider, with Jobs announcing in October that Apple would have a software development kit available for developers by February The SDK was released on March 6, The SDK is a free download for users of Mac personal computers.
It is not available for Microsoft Windows PCs.
