Conventions used
There are a number of text conventions used throughout this book.
CodeInText: Indicates code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles. For example: “Execute the terraform graph command:”
A block of code is set as follows:
var counter = 0
val mainView = findViewById<ConstraintLayout>(R.id.main)
val counterValue = mainView.findViewById<TextView>(
R.id.counter_value
)
val plusButton = mainView.findViewById<Button>(
R.id.plus
)
val minusButton = mainView.findViewById<Button>(
R.id.minus
)
When we wish to draw your attention to a particular part of a code block, the relevant lines or items are set in bold:
@Composable
fun Employee(employee: EmployeeUiModel) {
Row {
if (employee.imageUrl.isEmpty()) {
Spacer(modifier = Modifier.size(64.dp)
} else {
LoadedImage(
imageUrl = employee.imageUrl,
modifier = Modifier.size(64.dp)
)
}
Column {
Text(text = employee.name)
Text(text = employee.role.label)
}
}
}
Note: Although dependencies in the respective libs.versions.toml files may appear in two lines in the chapters, they should be added as one lines in your code.
Any command-line input or output is written as follows:
set KEYSTORE_PASSWORD=securepassword
Bold: Indicates a new term, an important word, or words that you see on the screen. For instance, words in menus or dialog boxes appear in the text like this. For example: “You will see a window with side tabs and Projects highlighted. Select the New Project option on the right-hand side.”
Warnings or important notes appear like this.
Tips and tricks appear like this.
