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: "Fingerprint sensor APIs require install time permission in the AndroidManifest.xml file."

A block of code is set as follows:

 @Override 
    protected void onCreate(Bundle savedInstanceState) { 
        super.onCreate(savedInstanceState); 
        mSensorManager = (SensorManager) 
        getSystemService(Context.SENSOR_SERVICE); 
        mSensor = mSensorManager.getDefaultSensor
       (Sensor.TYPE_SIGNIFICANT_MOTION);

New terms and important words are shown in bold.
