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 AppData directory is usually a hidden directory."

A block of code is set as follows:

package ${PACKAGE_NAME};

import android.app.Activity;
import android.os.Bundle;

#parse("File Header.java")
public class ${NAME} extends Activity {
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
    }
}

When we wish to draw your attention to a particular part of a code block, the relevant lines or items are set in bold:

if (savedInstanceState != null) {
    
}

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: "You can also open it by clicking on the Project button on the left edge of the screen."

Note

Warnings or important notes appear in a box like this.
