Conventions

In this book, you will find a number of styles of text that distinguish between different kinds of information. The following 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:

"Now, just like we saw in the earlier section, the application will store its data in the location /data/data/[package name]."

A block of code is set as follows:

shell@android:/data # cd /data/system
shell@android:/data/system # rm gesture.key

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

    <permission name="android.permission.BLUETOOTH" >
        <group gid="net_bt" />
    </permission>

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

$ unzip testing.apk
$ cd META-INF

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 the following:

"You could set up your own pattern by navigating to Settings | Security | Screen Lock."
