Step 2: Use the getdefasensensor method of SensorManager to obtain the sensor Object of the specified type;
1 Sensor sensor = mSensorManager. getdefasensensor (Sensor. TYPE_GRAVITY); // gravity sensing
Step 3: implement the onSensorChanged and onAccuracyChanged methods of the SensorEventListen

1. Framework object model2. kmdf program structure
Kmdf is a plug-and-play driver model:
1. A DriverEntry routine.
2. An evtdriverdeviceadd routine, similar to the adddevice routine of WDM.
3. One or more Io queues.
4. A callback routine for multiple active Io events is similar to the dispatchxxx of WDM.
5. plug-and-play and power management callback routines are supported.
6. Supported WMI callback routines for managing computer systems
7. Other call
Developers need to log on to the function, so they do not want to use a large database and directly use java to connect to access. Everything works on your machine, and direct url Connection and data source configuration are fine. Released to windows Server, unable to obtain the data connection. The system is 64-bit, and the office is 2010 32-bit. After searching for a long time, the problem was finally solved:
The 32-bit Access driver can be called
Kdriver. h defines DriverEntry, which calls
_ Create_driver_class_instance ();
Status = kdriver: driverinit (driverobject, registrypath );
The first sentence is defined in our driver. We will create a kdriver class object.
