The device vibrator can be used to set the vibration frequency to simulate the heartbeat vibration.
There are two ways to obtain the device vibrator:

As developers, we all know that the vibrator is responsible for controlling the vibration function of the mobile phone. The Vibrator System in Android is a small system dedicated to this function and provides the time-based Vibration function.
The vibrator system includes the driver, hardware abstraction layer, JNI, and Java fr

Here we reference the explanation in the book "Android system-level deep development-porting and debugging". The real vibrator code analysis is based on the Code in my project.

A, through the system services to obtain mobile phone vibration services, vibrator vibrator = (Vibrator) getsystemservice (Vibrator_service);
b, after the vibration service to detect the existence of vibrator:

Mobile phones have the effect of vibration. The day before yesterday, the flying knife removed a vibrator from the mobile phone, and asked me to tune it next week. Yesterday, I came to the company for a test and got it done. Let's talk about the process below.
In fact, the underlying driver has been completed in Android, that is, timed_gpio, which combines the timing function with the gpio function. vibration is a small DC motor, when the gpio port is

The vibrations in Android phones are implemented by vibrator. To set a vibration event, you need to know the length of the vibration, the period of vibration and so on.In Android vibrator, the vibration time is calculated in milliseconds (1/1000 seconds), so if the set time value is too small, it will not feel.Implemented by calling Vibrator's vibrate (long[] pattern, int repeat) method.The previous paramet

(!!! If it fails to run after the setting, click (stop now) and then click the element. Do not refresh it any more! It depends on you! Haha !)

Do not be too large. Be careful when the browser crashes. It is better to be less than 100.
