-/**
- * Handles the haptic feedback: a light buzz happening when the user
- * presses a soft key (UI button or capacitive key).  The haptic
- * feedback is controlled by:
- * - a system resource for the pattern
- *   The pattern used is tuned per device and stored in an internal
- *   resource (config_virtualKeyVibePattern.)
- * - a system setting HAPTIC_FEEDBACK_ENABLED.
- *   HAPTIC_FEEDBACK_ENABLED can be changed by the user using the
- *   system Settings activity. It must be rechecked each time the
- *   activity comes in the foreground (onResume).
- *
- * This class is not thread safe. It assumes it'll be called from the
- * UI thead.
- *
- * Typical usage:
- * --------------
- *   static private final boolean HAPTIC_ENABLED = true;
- *   private HapticFeedback mHaptic = new HapticFeedback();
- *
- *   protected void onCreate(Bundle icicle) {
- *     mHaptic.init((Context)this, HAPTIC_ENABLED);
- *   }
- *
- *   protected void onResume() {
- *     // Refresh the system setting.
- *     mHaptic.checkSystemSetting();
- *   }
- *
- *   public void foo() {
- *     mHaptic.vibrate();
- *   }
