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: "To edit your app manifest, open the folder manifests and double-click on the AndroidManifest.xml file."

A block of code is set as follows:

public class SampleActivity extends Activity { 
 
  @Override 
  protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
 
    // Called when the activity is first created 
}

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: "Click on this tab and select Android from the top drop-down menu."

Note

Warnings or important notes appear in a box like this.
