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: "To invoke the am command we will be using the adb shell command".

A block of code is set as follows:

dependencies {
    compile project(':dummylibrary')
}

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

fahrenheitEditNumber
.addTextChangedListener(
newFehrenheitToCelciusWatcher(fahrenheitEditNumber, celsiusEditNumber));
}

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

junit.framework.ComparisonFailure: expected:<[]> but was:<[123.45]>
at com.blundell.tut.EditNumberTests.testClear(EditNumberTests.java:31)
at java.lang.reflect.Method.invokeNative(Native Method)
at android.test.AndroidTestRunner.runTest(AndroidTestRunner.java:191)

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: "The first test performs a click on the Go button of the Forwarding Activity."
