From: http://blog.csdn.net/mr_raptor/article/details/80904741. Concept of Sensor Sensor, a sensor, is a large number of existing smart phones, such as G-sensor, lightssensor, proximitysensor, and temperaturesensor. It is used as an input device of the Android system, it is e

Ability to identify sensors and sensors The android sensor framework provides several methods that allow you to easily determine the sensors on the device during running. The API also provides several methods for you to determine the capabilities of each sensor, such as the maximum range, recognition rate, and power requirement. To identify sensors on a device, y

/second. Measured by Nexus S Mobile:Rotate horizontally counterclockwise and theZ axis is positive. The horizontal counterclockwise rotation, thez axis is negative. Rotate to the left and negative on they axis. Rotates to the right and they -axis is positive. Rotate up and thex axis is negative. Rotate downward and thex axis is positive. ST 's l3g series of gyroscope sensors are more popular,iphone4 and Google 's Nexus S used in this type of sensor. 5

Work AndroidJNIthreadOSJAVA programWe use the sensor interface to register the SensorListener as follows:**************************************** **********************ApiDemo:MGraphView = new GraphView (this );MSensorManager. registerListener (mGraphView ,....);**************************************** **********************The listener here is the control that changes when the sensor status changes.Reload
