Field Detail

PLAY_SOUND_DELAY

public static final int PLAY_SOUND_DELAY

The delay before playing a sound. This small period exists so the user can press another key (non-volume keys, too) to have it NOT be audible.

PhoneWindow will implement this part.

Constant Field Values

VIBRATE_DELAY

public static final int VIBRATE_DELAY

The delay before vibrating. This small period exists so if the user is moving to silent mode, it will not emit a short vibrate (it normally would since vibrate is between normal mode and silent mode using hardware keys).
