Android practice simple tutorial-62nd guns (electronic Sensor exact Compass) Here we use the sensor provided by the mobile phone to implement a simple small example of the electronic compass. You can learn how to use the SensorManager class, SensorEventListener and its overwriting method. First, create a layout file: Then the Activity file:

Android location sensor The Android platform provides two sensors to determine the location of the device. These two sensors are magnetic field sensors and direction sensors. The Android platform also provides a sensor (proximity

Android motion sensor Android motion sensor The Android platform supports some sensors used to monitor device movements (five such sensors ). Two of them are pure hardware sensors. The other three (Gravity Sensors, linear acceleration sensors, and Rotation Vector Sensors) ma

The

Now there are all kinds of sensors in Android phones, such as accelerometers, gyroscopes and the like, I now use a total of nine sensors in the Vivo V3 phone:Lis3dh-accel : Tri-axis acceleration sensorTmd277x-proximity : Near distance sensorTmd277x-light : Light sensorYas533-orientation : Direction sensorYas533-pseudo-gyro : Motion sensorYas533-linear-acceleration : Linear acceleration SensorYas533-rotation

. type_proximiy: Proximity sensor Sensor. type_temperature: Temperature Sensor Some mobile phones do not support some sensor devices. You can determine whether the sensor is null. If it is null, You can prompt the user. You can

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 proximi
