B4A is intended to develop Android applications (APKs). Most of the IDEs require at least basic knowledge of software development, and B4A is not an exception. Luckily, there is plenty of documentation available online. Installing the product can be somewhat troublesome as it requires additional libraries and platforms, for instance Java and .NET.
The tool has a well-designed and modern-looking interface, which in many respects looks similar to those of other IDEs. In this regard, most of the space is occupied by the code editor. Moreover, the availability of tabs helps you work on various parts of your project simultaneously. It is great that it can autocomplete code while you type, which makes programming more fluid. Besides, the tool lets you fold or unfold parts of the code to help you focus on the most important parts. In addition, the program comes with a built-in debugger to help you avoid predictable errors in your applications.
Fortunately, B4A also has a visual designer, in which you can place the graphic elements to control the look-and-feel of the APK. Conveniently, the tool lets you use multiple layouts according to the size and shape of the target screen, which depends on the kind of device. What is more, you do not need to do this by hand, since there are designer scripts to make the location and size of the graphic elements adapt to different screens. Finally, there is even a WYSIWYG designer that lets you preview what the application will look like. more
