Android 的振动...是否存在于所有 Android 设备中？
我知道振动是由硬件产生的，并且根据 OEM 的不同，每个 Android 设备中是否存在振动，但您认为所有 Android 智能手机中都存在振动吗？
还有一个问题，如何通过代码检查设备是否存在振动？
提前谢谢。
I know that the vibration is produced by hardware and it would be exists or not in each Android-device depending of the OEM, but do you consider that the vibrations exists in all smarthphones that had Android?
Another question, how will do you check by code if the vibration exists in the device?
Thx in advanced.

要使用振动，您需要在清单中添加此权限。
基于此，Android 市场会自动排除不包含它的设备。然而，可以安全地假设它存在于所有设备中，并且您不需要在代码中执行任何额外操作来检查它。
To use Vibrations you need to add this permission in the manifest.
Based on this the Android market would automatically exclude the devices that does not include it. However it is safe to assume that it would exist in all device and you need to do nothing extra in the code for checking it.
我只是假设所有手机都具有手机振动的功能，而不编写任何代码来检查它。
I would just assume the ability for a phone to vibrate exists in all phones and not write any code to check for it.
