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: "Now, extract the downloaded ZIP package and run the eclipse.exe executable."

A block of code is set as follows:

dependencies {
    compile 'com.google.android.gms:play-services:7.5.0'
    compile 'com.android.support:appcompat-v7:21.0.3'
}

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

if(db.getMarkerCount() > 0){
            List<Marker> markerList = db.getAllMarkers();
            for (int i = 0; i < db.getMarkerCount(); i++) {
                Marker mkr = markerList.get(i);

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

sudo dpkg --add-architecture i386
sudo apt-get update

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: "Now, check the Developer Tools box and select Next."
