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: "If you go to this folder and call the command adb, you will see on the screen a list of the available options."

A block of code is set as follows:

<resources>
    <style name="Theme.NoBackground" parent="android:Theme">
      <item name="android:windowBackground">@null</item>
    </style>
</resources>

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

adb shell dumbsys gfxinfo <PACKAGE_NAME>

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: "To debug the overdraw on the device, Android provides a helpful tool that can be enabled inside the Developer options."

Note
