Conventions

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

Code words in text are shown as follows: "Edit your system's PATH to include <android_sdk>/platform-tools and <android_sdk>/tools."

A block of code is set as follows:

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android=
  "http://schemas.android.com/apk/res/android"
  package="com.nummist.secondsight"
  android:versionCode="1"
  android:versionName="1.0">

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

mCameraView.enableView();
      mBgr = new Mat();
      mCurveFilters = new Filter[] {
 new NoneFilter(),
 new PortraCurveFilter(),
 new ProviaCurveFilter(),

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

$ cd /etc/udev/rules.d/
$ sudo touch 51-android.rules
$ sudo chmod a+r 51-android-rules

New terms and important words are shown in bold. Words that you see on the screen, in menus or dialog boxes for example, appear in the text like this: "clicking on the Next button moves you to the next screen".
