-/**
- * 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();
- * }
