The Android platform provides two sensors to determine the location of the device, and these two sensors are magnetic field sensors and directional sensors. The Android platform also provides sensors (proximity sensors) that measure the distance from the front of a device to a nearby object. magnetic field sensors and

Sensor Introduction The android sensor framework allows you to access multiple types of sensors. Some sensors are hardware-based and some are software-based. Hardware-based sensors are physical components built in with handheld or flat devices. They obtain data by directly measuring specific environmental properties, such as acceleration,

After Android2.2, orientation sensors was deprecated.The official proposal is to use acceleration and magnetic sensor to calculateOn this question, csdn on a very good blog post.http://blog.csdn.net/flowingflying/article/details/43233315On stack Overflow:Http://stackoverflow.com/questions/10291322/what-is-the-alternative-to-android-orientation-sensorUse the words

. Which sensors are provided in Android: 1. Acceleration Sensor (gravity sensor) 2. gyroscope Sensor 3. Optical Sensors 5. Constant Magnetic Field Sensor 6. Direction Sensor 7. Constant

. Environment Sensors These sensors measure environmental parameters such as ambient air temperature and pressure, illuminance and humidity. This type of sensor includes a barometer, spectrophotometer, and a thermometer. 3. Position Sensor These sensors are used to measure the physical location of a device. This type of sensor includes a direction

Z axis of the Accelrator: Z =-10 When the mobile phone screen is placed vertically, z = 0 When the mobile phone screen is placed horizontally down, z = 10 3. When x is changed to + 5, the mobile phone screen changes to vertical.When x changes to-5, the mobile phone screen changes to horizontal 4. classes related to Android sensors are different in SDK1.1 and SDK1.5, so the implementation code is different. 5. And
