GetDefaultSensor(SensorType)
Use this method to get the default sensor for a given type.
[Android.Runtime.Register("getDefaultSensor", "(I)Landroid/hardware/Sensor;", "GetGetDefaultSensor_IHandler")]
public virtual Android.Hardware.Sensor? GetDefaultSensor (Android.Hardware.SensorType type);[<Android.Runtime.Register("getDefaultSensor", "(I)Landroid/hardware/Sensor;", "GetGetDefaultSensor_IHandler")>]
abstract member GetDefaultSensor : Android.Hardware.SensorType -> Android.Hardware.Sensor

- SensorType
of sensors requested
Returns
the default sensor matching the requested type if one exists and the application has the necessary permissions, or null otherwise.
- Attributes
Remarks
Use this method to get the default sensor for a given type. Note that the returned sensor could be a composite sensor, and its data could be averaged or filtered. If you need to access the raw sensors use SensorManager#getSensorList(int) getSensorList.

type of sensor requested
- wakeUp
- Boolean
flag to indicate whether the Sensor is a wake-up or non wake-up sensor.
Returns
the default sensor matching the requested type and wakeUp properties if one exists and the application has the necessary permissions, or null otherwise.
- Attributes
Remarks
Return a Sensor with the given type and wakeUp properties. If multiple sensors of this type exist, any one of them may be returned.
For example, <ul> <li>getDefaultSensor(Sensor#TYPE_ACCELEROMETER, true) returns a wake-up accelerometer sensor if it exists. </li> <li>getDefaultSensor(Sensor#TYPE_PROXIMITY, false) returns a non wake-up proximity sensor if it exists. </li> <li>getDefaultSensor(Sensor#TYPE_PROXIMITY, true) returns a wake-up proximity sensor which is the same as the Sensor returned by #getDefaultSensor(int). </li> </ul>
<p class="note"> Note: Sensors like Sensor#TYPE_PROXIMITY and Sensor#TYPE_SIGNIFICANT_MOTION are declared as wake-up sensors by default. </p>
