Member Function Documentation

◆ shouldShowButton()

default boolean shouldShowButton ( Activity activity )

The default is that the button will be shown for all Activities.

Note that as the default implementation returns true, the only reason to provide a different implementation is to return false, i.e. to prevent the launcher button from being shown for an Activity.

◆ shouldShowCoachmark()

default boolean shouldShowCoachmark ( )

This screen is normally shown to explain the use of the Launcher, the first time it appears after the app is activated. This delegate method may be used to override this behavior.

Note that as the default implementation returns true, the only reason to provide a different implementation is to return false, i.e. to prevent the coaching screen from being shown.

Returns: Whether to show the coaching screen.

◆ onSettingsCommand() [1/2]

default void onSettingsCommand ( )

The application should show its settings screen. Note that this will always be called on the UI thread.

◆ onSettingsCommand() [2/2]

default void onSettingsCommand ( Activity originActivity )

The application should show its settings screen. Note that this will always be called on the UI thread.

This flavor of onSettingsCommand is preferred, and will always be called if it is overridden.
