WebIconDatabase

java.lang.Object

public abstract class WebIconDatabase extends Object

Functions for manipulating the icon database used by WebView. These functions require that a WebView be constructed before being invoked and WebView.getIconDatabase() will return a WebIconDatabase object. This WebIconDatabase object is a single instance and all methods operate on that single object. The main use-case for this class is calling {@link #open} to enable favicon functionality on all WebView instances in this process.

deprecated: This class is only required when running on devices up to {@link android.os.Build.VERSION_CODES#JELLY_BEAN_MR2}
