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: "Edit the MainActivity Java class so that it extends CardboardActivity and implements CardboardView.StereoRenderer."

A block of code is set as follows:

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        CardboardView cardboardView = (CardboardView) findViewById(R.id.cardboard_view);
        cardboardView.setRenderer(this);
        setCardboardView(cardboardView);
    }

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

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        CardboardView cardboardView = (CardboardView) findViewById(R.id.cardboard_view);
        cardboardView.setRenderer(this);
        setCardboardView(cardboardView);
    }

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

git clone https://github.com/googlesamples/cardboard-java.git

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: "In Android Studio, select File | New | New Module…. Select Import .JAR/.AAR Package."

Note

Warnings or important notes appear in a box like this.
