當處於一個寧靜的環境，例如在劇院、圖書館、會議、教堂或嘈吵環境，手機便利用機內的震動功能作為提示，通知用戶，便可以避免錯過重要時刻。Android Studio 提共了手機震動類（Vibrator Class），可以程式震動功能，方便編程。

Constants |
Description |
|
|
int |
VIBRATION_EFFECT_SUPPORT_NO |
Vibration effect support: unsupported - This effect is not natively supported by the underlying hardware, although the system may still play a fallback vibration. Constant Value: 2 (0x00000002) |
|
int |
VIBRATION_EFFECT_SUPPORT_UNKNOWN |
Vibration effect support: unknown - The hardware doesn't report its supported effects, so we can't determine whether the effect is supported or not. Constant Value: 0 (0x00000000) |
|
int |
VIBRATION_EFFECT_SUPPORT_YES |
Vibration effect support: supported - This effect is supported by the underlying hardware. Constant Value: 1 (0x00000001) |
