Conventions used

There are a number of text conventions used throughout this book.

Code in text: Indicates code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles. Here is an example: “In our second example, we have two functions, main() and reverseString(). main() takes nothing in its input.”

A block of code is set as follows:

fun main() {
    val stringToBeReversed = "Community"
    println(reverseString(stringToBeReversed))
}
fun reverseString(stringToReverse: String): String {
    return stringToReverse.reversed()
}

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

data class City(
    val id: Int,
    @StringRes val nameResourceId: Int,
    @DrawableRes val imageResourceId: Int
)

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

$ git clone [email protected]:PacktPublishing/Modern-Android-13-Development-Cookbook.git

Bold: Indicates a new term, an important word, or words that you see on screen. For instance, words in menus or dialog boxes appear in bold. Here is an example: “Click Finish and wait for Gradle to sync.”
