Conventions

In this book, you will find a number of text styles that distinguish between different kinds of information. Here are some examples of these styles and an explanation of their meaning.

Code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles are shown as follows: "The general Android kernel source code is in the kernel/common folder , which looks very much like the Vanilla kernel."

A block of code is set as follows:

static struct hw_module_methods_t lights_module_methods = {
  .open = open_lights,
};

Any command-line input or output is written as follows:

$ ls
Light.java LightsManager.java LightsService.java

New terms and important words are shown in bold. Words that you see on the screen, for example, in menus or dialog boxes, appear in the text like this: "We should set the launch type to Standard Create Process Launcher."

Warnings or important notes appear in a box like this.

Tips and tricks appear like this.
