Most Android-powered devices have built-in sensors that measure motion, orientation and various environmental conditions. We can access sensors available on the device and acquire raw sensor data by using the Android sensor framework. There are software-based and hardware-based sensors.
The sensor framework is part of the android.hardware package and includes below classes and interfaces:
SensorManager
Sensor
SensorEvent
SensorEventListener
Attn: make sure to DISABLE sensors we don’t need, especially when our activity is paused.
–register under onResume();
–unRegister under onPause();
@Override protected void onResume() { super.onResume(); mSensorManager.registerListener(this,mSensor,SensorManager.SENSOR_DELAY_UI); } @Override protected void onPause() { super.onPause(); mSensorManager.unregisterListener(this); }
