SensorManager


abstract class SensorManager
kotlin.Any
   ↳ android.hardware.SensorManager

SensorManager lets you access the device's sensors.

Always make sure to disable sensors you don't need, especially when your activity is paused. Failing to do so can drain the battery in just a few hours. Note that the system will not disable sensors automatically when the screen turns off.

Note: Don't use this mechanism with a Trigger Sensor, have a look at TriggerEventListener. Sensor#TYPE_SIGNIFICANT_MOTION is an example of a trigger sensor.

In order to access sensor data at high sampling rates (i.e. greater than 200 Hz for SensorEventListener and greater than SensorDirectChannel#RATE_NORMAL for SensorDirectChannel), apps must declare the android.Manifest.permission#HIGH_SAMPLING_RATE_SENSORS permission in their AndroidManifest.xml file.

public class SensorActivity extends Activity implements SensorEventListener {
      private final SensorManager mSensorManager;
      private final Sensor mAccelerometer;
 
      public SensorActivity() {
          mSensorManager = (SensorManager)getSystemService(SENSOR_SERVICE);
          mAccelerometer = mSensorManager.getDefaultSensor(Sensor.TYPE_ACCELEROMETER);
      }
 
      protected void onResume() {
          super.onResume();
          mSensorManager.registerListener(this, mAccelerometer, SensorManager.SENSOR_DELAY_NORMAL);
      }
 
      protected void onPause() {
          super.onPause();
          mSensorManager.unregisterListener(this);
      }
 
      public void onAccuracyChanged(Sensor sensor, int accuracy) {
      }
 
      public void onSensorChanged(SensorEvent event) {
      }
  }

Public methods

cancelTriggerSensor

Added in API level 18
open fun cancelTriggerSensor(
    listener: TriggerEventListener!,
    sensor: Sensor!
): Boolean

Cancels receiving trigger events for a trigger sensor.

Note that a Trigger sensor will be auto disabled if TriggerEventListener#onTrigger(TriggerEvent) has triggered. This method is provided in case the user wants to explicitly cancel the request to receive trigger events.

Parameters
listener TriggerEventListener!: The listener on which the TriggerEventListener#onTrigger(TriggerEvent) is delivered.It should be the same as the one used in requestTriggerSensor(android.hardware.TriggerEventListener,android.hardware.Sensor)
sensor Sensor!: The sensor for which the trigger request should be canceled. If null, it cancels receiving trigger for all sensors associated with the listener.
Return
Boolean true if successfully canceled.
Exceptions
java.lang.IllegalArgumentException when sensor is a trigger sensor.

createDirectChannel

Added in API level 26
open fun createDirectChannel(mem: MemoryFile!): SensorDirectChannel!

Create a sensor direct channel backed by shared memory wrapped in MemoryFile object. The resulting channel can be used for delivering sensor events to native code, other processes, GPU/DSP or other co-processors without CPU intervention. This is the recommended for high performance sensor applications that use high sensor rates (e.g. greater than 200Hz) and cares about sensor event latency. Use the returned android.hardware.SensorDirectChannel object to configure direct report of sensor events. After use, call android.hardware.SensorDirectChannel#close() to free up resource in sensor system associated with the direct channel.

Parameters
mem MemoryFile!: A android.os.MemoryFile shared memory object.
Return
SensorDirectChannel! A android.hardware.SensorDirectChannel object.
Exceptions
java.lang.NullPointerException when mem is null.
UncheckedIOException if not able to create channel.

    createDirectChannel

    Added in API level 26
    open fun createDirectChannel(mem: HardwareBuffer!): SensorDirectChannel!

    Create a sensor direct channel backed by shared memory wrapped in HardwareBuffer object. The resulting channel can be used for delivering sensor events to native code, other processes, GPU/DSP or other co-processors without CPU intervention. This is the recommended for high performance sensor applications that use high sensor rates (e.g. greater than 200Hz) and cares about sensor event latency. Use the returned android.hardware.SensorDirectChannel object to configure direct report of sensor events. After use, call android.hardware.SensorDirectChannel#close() to free up resource in sensor system associated with the direct channel.

    Parameters
    mem HardwareBuffer!: A android.hardware.HardwareBuffer shared memory object.

      flush

      Added in API level 19
      open fun flush(listener: SensorEventListener!): Boolean

      Flushes the FIFO of all the sensors registered for this listener. If there are events in the FIFO of the sensor, they are returned as if the maxReportLatency of the FIFO has expired. Events are returned in the usual way through the SensorEventListener. This call doesn't affect the maxReportLatency for this sensor. This call is asynchronous and returns immediately. onFlushCompleted is called after all the events in the batch at the time of calling this method have been delivered successfully. If the hardware doesn't support flush, it still returns true and a trivial flush complete event is sent after the current event for all the clients registered for this sensor.

      Parameters
      listener SensorEventListener!: A SensorEventListener object which was previously used in a registerListener call.
      Return
      Boolean true if the flush is initiated successfully on all the sensors registered for this listener, false if no sensor is previously registered for this listener or flush on one of the sensors fails.
      Exceptions
      java.lang.IllegalArgumentException when listener is null.

      getAltitude

      Added in API level 9
      open static fun getAltitude(
          p0: Float,
          p: Float
      ): Float

      Computes the Altitude in meters from the atmospheric pressure and the pressure at sea level.

      Typically the atmospheric pressure is read from a Sensor#TYPE_PRESSURE sensor. The pressure at sea level must be known, usually it can be retrieved from airport databases in the vicinity. If unknown, you can use PRESSURE_STANDARD_ATMOSPHERE as an approximation, but absolute altitudes won't be accurate.

      To calculate altitude differences, you must calculate the difference between the altitudes at both points. If you don't know the altitude as sea level, you can use PRESSURE_STANDARD_ATMOSPHERE instead, which will give good results considering the range of pressure typically involved.

        float altitude_difference = getAltitude(SensorManager.PRESSURE_STANDARD_ATMOSPHERE, pressure_at_point2) - getAltitude(SensorManager.PRESSURE_STANDARD_ATMOSPHERE, pressure_at_point1);

      Parameters
      p0 Float: pressure at sea level
      p Float: atmospheric pressure
      Return
      Float Altitude in meters

      Added in API level 9
      open static fun getAngleChange(
          angleChange: FloatArray!,
          R: FloatArray!,
          prevR: FloatArray!
      ): Unit

      Helper function to compute the angle change between two rotation matrices. Given a current rotation matrix (R) and a previous rotation matrix (prevR) computes the intrinsic rotation around the z, x, and y axes which transforms prevR to R. outputs a 3 element vector containing the z, x, and y angle change at indexes 0, 1, and 2 respectively.

      Each input matrix is either as a 3x3 or 4x4 row-major matrix depending on the length of the passed array:

      If the array length is 9, then the array elements represent this matrix

      /  R[ 0]   R[ 1]   R[ 2]   \
          |  R[ 3]   R[ 4]   R[ 5]   |
          \  R[ 6]   R[ 7]   R[ 8]   /
       

      If the array length is 16, then the array elements represent this matrix

      /  R[ 0]   R[ 1]   R[ 2]   R[ 3]  \
          |  R[ 4]   R[ 5]   R[ 6]   R[ 7]  |
          |  R[ 8]   R[ 9]   R[10]   R[11]  |
          \  R[12]   R[13]   R[14]   R[15]  /
       
      See getOrientation for more detailed definition of the output.

      getInclination

      Added in API level 3
      open static fun getInclination(I: FloatArray!): Float

      Computes the geomagnetic inclination angle in radians from the inclination matrix I returned by getRotationMatrix.

      Parameters
      I FloatArray!: inclination matrix see getRotationMatrix.
      Return
      Float The geomagnetic inclination angle in radians.

      getOrientation

      Added in API level 3
      open static fun getOrientation(
          R: FloatArray!,
          values: FloatArray!
      ): FloatArray!

      Computes the device's orientation based on the rotation matrix.

      When it returns, the array values are as follows:

      • values[0]: Azimuth, angle of rotation about the -z axis. This value represents the angle between the device's y axis and the magnetic north pole. When facing north, this angle is 0, when facing south, this angle is π. Likewise, when facing east, this angle is π/2, and when facing west, this angle is -π/2. The range of values is -π to π.
      • values[1]: Pitch, angle of rotation about the x axis. This value represents the angle between a plane parallel to the device's screen and a plane parallel to the ground. Assuming that the bottom edge of the device faces the user and that the screen is face-up, tilting the top edge of the device toward the ground creates a positive pitch angle. The range of values is -π/2 to π/2.
      • values[2]: Roll, angle of rotation about the y axis. This value represents the angle between a plane perpendicular to the device's screen and a plane perpendicular to the ground. Assuming that the bottom edge of the device faces the user and that the screen is face-up, tilting the left edge of the device toward the ground creates a positive roll angle. The range of values is -π to π.

      Applying these three rotations in the azimuth, pitch, roll order transforms an identity matrix to the rotation matrix passed into this method. Also, note that all three orientation angles are expressed in radians.

      Parameters
      R FloatArray!: rotation matrix see getRotationMatrix.
      values FloatArray!: an array of 3 floats to hold the result.
      Return
      FloatArray! The array values passed as argument.

      getQuaternionFromVector

      Added in API level 9
      open static fun getQuaternionFromVector(
          Q: FloatArray!,
          rv: FloatArray!
      ): Unit

      Helper function to convert a rotation vector to a normalized quaternion. Given a rotation vector (presumably from a ROTATION_VECTOR sensor), returns a normalized quaternion in the array Q. The quaternion is stored as [w, x, y, z]

      Parameters
      rv FloatArray!: the rotation vector to convert
      Q FloatArray!: an array of floats in which to store the computed quaternion

      getRotationMatrix

      Added in API level 3
      open static fun getRotationMatrix(
          R: FloatArray!,
          I: FloatArray!,
          gravity: FloatArray!,
          geomagnetic: FloatArray!
      ): Boolean

      Computes the inclination matrix I as well as the rotation matrix R transforming a vector from the device coordinate system to the world's coordinate system which is defined as a direct orthonormal basis, where:

      • X is defined as the vector product Y.Z (It is tangential to the ground at the device's current location and roughly points East).
      • Y is tangential to the ground at the device's current location and points towards the magnetic North Pole.
      • Z points towards the sky and is perpendicular to the ground.

      By definition:

      [0 0 g] = R * gravity (g = magnitude of gravity)

      [0 m 0] = I * R * geomagnetic (m = magnitude of geomagnetic field)

      R is the identity matrix when the device is aligned with the world's coordinate system, that is, when the device's X axis points toward East, the Y axis points to the North Pole and the device is facing the sky.

      I is a rotation matrix transforming the geomagnetic vector into the same coordinate space as gravity (the world's coordinate space). I is a simple rotation around the X axis. The inclination angle in radians can be computed with getInclination.

      Each matrix is returned either as a 3x3 or 4x4 row-major matrix depending on the length of the passed array:

      If the array length is 16:

      /  M[ 0]   M[ 1]   M[ 2]   M[ 3]  \
          |  M[ 4]   M[ 5]   M[ 6]   M[ 7]  |
          |  M[ 8]   M[ 9]   M[10]   M[11]  |
          \  M[12]   M[13]   M[14]   M[15]  /
       
      This matrix is ready to be used by OpenGL ES's glLoadMatrixf(float[], int).

      Note that because OpenGL matrices are column-major matrices you must transpose the matrix before using it. However, since the matrix is a rotation matrix, its transpose is also its inverse, conveniently, it is often the inverse of the rotation that is needed for rendering; it can therefore be used with OpenGL ES directly.

      Also note that the returned matrices always have this form:

      /  M[ 0]   M[ 1]   M[ 2]   0  \
          |  M[ 4]   M[ 5]   M[ 6]   0  |
          |  M[ 8]   M[ 9]   M[10]   0  |
          \      0       0       0   1  /
       

      If the array length is 9:

      /  M[ 0]   M[ 1]   M[ 2]  \
          |  M[ 3]   M[ 4]   M[ 5]  |
          \  M[ 6]   M[ 7]   M[ 8]  /
       

      The inverse of each matrix can be computed easily by taking its transpose.

      The matrices returned by this function are meaningful only when the device is not free-falling and it is not close to the magnetic north. If the device is accelerating, or placed into a strong magnetic field, the returned matrices may be inaccurate.

      Parameters
      R FloatArray!: is an array of 9 floats holding the rotation matrix R when this function returns. R can be null.

      I FloatArray!: is an array of 9 floats holding the rotation matrix I when this function returns. I can be null.

      gravity FloatArray!: is an array of 3 floats containing the gravity vector expressed in the device's coordinate. You can simply use the values returned by a SensorEvent of a Sensor of type TYPE_ACCELEROMETER.

      geomagnetic FloatArray!: is an array of 3 floats containing the geomagnetic vector expressed in the device's coordinate. You can simply use the values returned by a SensorEvent of a Sensor of type TYPE_MAGNETIC_FIELD.
      Return
      Boolean true on success, false on failure (for instance, if the device is in free fall). Free fall is defined as condition when the magnitude of the gravity is less than 1/10 of the nominal value. On failure the output matrices are not modified.

      Added in API level 9
      open static fun getRotationMatrixFromVector(
          R: FloatArray!,
          rotationVector: FloatArray!
      ): Unit

      Helper function to convert a rotation vector to a rotation matrix. Given a rotation vector (presumably from a ROTATION_VECTOR sensor), returns a 9 or 16 element rotation matrix in the array R. R must have length 9 or 16. If R.length == 9, the following matrix is returned:

      /  R[ 0]   R[ 1]   R[ 2]   \
          |  R[ 3]   R[ 4]   R[ 5]   |
          \  R[ 6]   R[ 7]   R[ 8]   /
       
      If R.length == 16, the following matrix is returned:
      /  R[ 0]   R[ 1]   R[ 2]   0  \
          |  R[ 4]   R[ 5]   R[ 6]   0  |
          |  R[ 8]   R[ 9]   R[10]   0  |

      Return
      Boolean true if the sensor is supported and successfully enabled

      registerListener

      Added in API level 3
      open fun registerListener(
          listener: SensorEventListener!,
          sensor: Sensor!,
          samplingPeriodUs: Int
      ): Boolean

      Registers a SensorEventListener for the given sensor at the given sampling frequency.

      The events will be delivered to the provided SensorEventListener as soon as they are available. To reduce the power consumption, applications can use registerListener(android.hardware.SensorEventListener,android.hardware.Sensor,int,int) instead and specify a positive non-zero maximum reporting latency.

      In the case of non-wake-up sensors, the events are only delivered while the Application Processor (AP) is not in suspend mode. See Sensor#isWakeUpSensor() for more details. To ensure delivery of events from non-wake-up sensors even when the screen is OFF, the application registering to the sensor must hold a partial wake-lock to keep the AP awake, otherwise some events might be lost while the AP is asleep. Note that although events might be lost while the AP is asleep, the sensor will still consume power if it is not explicitly deactivated by the application. Applications must unregister their SensorEventListeners in their activity's onPause() method to avoid consuming power while the device is inactive. See registerListener(android.hardware.SensorEventListener,android.hardware.Sensor,int,int) for more details on hardware FIFO (queueing) capabilities and when some sensor events might be lost.

      In the case of wake-up sensors, each event generated by the sensor will cause the AP to wake-up, ensuring that each event can be delivered. Because of this, registering to a wake-up sensor has very significant power implications. Call Sensor#isWakeUpSensor() to check whether a sensor is a wake-up sensor. See registerListener(android.hardware.SensorEventListener,android.hardware.Sensor,int,int) for information on how to reduce the power impact of registering to wake-up sensors.

      Note: Don't use this method with one-shot trigger sensors such as Sensor#TYPE_SIGNIFICANT_MOTION. Use requestTriggerSensor(android.hardware.TriggerEventListener,android.hardware.Sensor) instead. Use Sensor#getReportingMode() to obtain the reporting mode of a given sensor.

      Parameters
      listener SensorEventListener!: A SensorEventListener object.
      sensor Sensor!: The Sensor to register to.
      samplingPeriodUs Int: The rate sensor events are delivered at. This is only a hint to the system. Events may be received faster or slower than the specified rate. Usually events are received faster. The value must be one of SENSOR_DELAY_NORMAL, SENSOR_DELAY_UI, SENSOR_DELAY_GAME, or SENSOR_DELAY_FASTEST or, the desired delay between events in microseconds. Specifying the delay in microseconds only works from Android 2.3 (API level 9) onwards. For earlier releases, you must use one of the SENSOR_DELAY_* constants.
      Return
      Boolean true if the sensor is supported and successfully enabled.

      registerListener

      Added in API level 19
      open fun registerListener(
          listener: SensorEventListener!,
          sensor: Sensor!,
          samplingPeriodUs: Int,
          maxReportLatencyUs: Int
      ): Boolean

      Registers a SensorEventListener for the given sensor at the given sampling frequency and the given maximum reporting latency.

      This function is similar to registerListener(android.hardware.SensorEventListener,android.hardware.Sensor,int) but it allows events to stay temporarily in the hardware FIFO (queue) before being delivered. The events can be stored in the hardware FIFO up to maxReportLatencyUs microseconds. Once one of the events in the FIFO needs to be reported, all of the events in the FIFO are reported sequentially. This means that some events will be reported before the maximum reporting latency has elapsed.

      When maxReportLatencyUs is 0, the call is equivalent to a call to registerListener(android.hardware.SensorEventListener,android.hardware.Sensor,int), as it requires the events to be delivered as soon as possible.

      When sensor.maxFifoEventCount() is 0, the sensor does not use a FIFO, so the call will also be equivalent to registerListener(android.hardware.SensorEventListener,android.hardware.Sensor,int).

      Setting maxReportLatencyUs to a positive value allows to reduce the number of interrupts the AP (Application Processor) receives, hence reducing power consumption, as the AP can switch to a lower power state while the sensor is capturing the data. This is especially important when registering to wake-up sensors, for which each interrupt causes the AP to wake up if it was in suspend mode. See Sensor#isWakeUpSensor() for more information on wake-up sensors.

      Note: Don't use this method with one-shot trigger sensors such as Sensor#TYPE_SIGNIFICANT_MOTION. Use requestTriggerSensor(android.hardware.TriggerEventListener,android.hardware.Sensor) instead.

      Parameters
      listener SensorEventListener!: A SensorEventListener object that will receive the sensor events. If the application is interested in receiving flush complete notifications, it should register with SensorEventListener2 instead.
      sensor Sensor!: The Sensor to register to.
      samplingPeriodUs Int: The desired delay between two consecutive events in microseconds. This is only a hint to the system. Events may be received faster or slower than the specified rate. Usually events are received faster. Can be one of SENSOR_DELAY_NORMAL, SENSOR_DELAY_UI, SENSOR_DELAY_GAME, SENSOR_DELAY_FASTEST or the delay in microseconds.
      maxReportLatencyUs Int: Maximum time in microseconds that events can be delayed before being reported to the application. A large value allows reducing the power consumption associated with the sensor. If maxReportLatencyUs is set to zero, events are delivered as soon as they are available, which is equivalent to calling registerListener(android.hardware.SensorEventListener,android.hardware.Sensor,int).
      Return
      Boolean true if the sensor is supported and successfully enabled.

      ): Boolean

      Registers a SensorEventListener for the given sensor. Events are delivered in continuous mode as soon as they are available. To reduce the power consumption, applications can use registerListener(android.hardware.SensorEventListener,android.hardware.Sensor,int,int) instead and specify a positive non-zero maximum reporting latency.

      Note: Don't use this method with a one shot trigger sensor such as Sensor#TYPE_SIGNIFICANT_MOTION. Use requestTriggerSensor(android.hardware.TriggerEventListener,android.hardware.Sensor) instead.

      remapCoordinateSystem

      Added in API level 3
      open static fun remapCoordinateSystem(
          inR: FloatArray!,
          X: Int,
          Y: Int,
          outR: FloatArray!
      ): Boolean

      Rotates the supplied rotation matrix so it is expressed in a different coordinate system. This is typically used when an application needs to compute the three orientation angles of the device (see getOrientation) in a different coordinate system.

      When the rotation matrix is used for drawing (for instance with OpenGL ES), it usually doesn't need to be transformed by this function, unless the screen is physically rotated, in which case you can use Display.getRotation() to retrieve the current rotation of the screen. Note that because the user is generally free to rotate their screen, you often should consider the rotation in deciding the parameters to use here.

      Examples:

      • Using the camera (Y axis along the camera's axis) for an augmented reality application where the rotation angles are needed:
        • remapCoordinateSystem(inR, AXIS_X, AXIS_Z, outR);

      • Using the device as a mechanical compass when rotation is Surface.ROTATION_90:
        • remapCoordinateSystem(inR, AXIS_Y, AXIS_MINUS_X, outR);

        Beware of the above example. This call is needed only to account for a rotation from its natural orientation when calculating the rotation angles (see getOrientation). If the rotation matrix is also used for rendering, it may not need to be transformed, for instance if your Activity is running in landscape mode.

      Since the resulting coordinate system is orthonormal, only two axes need to be specified.

      Parameters
      inR FloatArray!: the rotation matrix to be transformed. Usually it is the matrix returned by getRotationMatrix.
      X Int: defines the axis of the new coordinate system that coincide with the X axis of the original coordinate system.
      Y Int: defines the axis of the new coordinate system that coincide with the Y axis of the original coordinate system.
      outR FloatArray!: the transformed rotation matrix. inR and outR should not be the same array.
      Return
      Boolean true on success. false if the input parameters are incorrect, for instance if X and Y define the same axis. Or if inR and outR don't have the same length.

      Requests receiving trigger events for a trigger sensor.

      When the sensor detects a trigger event condition, such as significant motion in the case of the Sensor#TYPE_SIGNIFICANT_MOTION, the provided trigger listener will be invoked once and then its request to receive trigger events will be canceled. To continue receiving trigger events, the application must request to receive trigger events again.

      Parameters
      listener TriggerEventListener!: The listener on which the TriggerEventListener#onTrigger(TriggerEvent) will be delivered.
      sensor Sensor!: The sensor to be enabled.
      Return
      Boolean true if the sensor was successfully enabled.
