Android Sensors

Android categorizes sensors into motion, environment, and position sensors for various measurements like motion, environmental conditions, and physical device position.

Accelerometer Sensor

Measures acceleration force on (x, y, z) axes, detecting movement, tilts, and vibrations for orientation, direction, and linear motion detection.

Using the Accelerometer

Involves steps like implementing SensorEventListener, getting Sensor Service, displaying readings, calculating force, registering/unregistering listeners.

Retrieving Sensor Information

Utilize SensorManager to list available sensors on Android devices using code snippets for SensorManager and sensorList.

Location-Based Services

Utilize classes like LocationManager, LocationProvider, and Geocoder for location-based apps, respecting user privacy, obtaining user location, and developing location-based service apps with permissions, providers, Geocoder, and LocationListener.
