Accelerometer

getCurrentAccelerometer

• Description

  Get the current accelerometer data.

• Parameters

  Attribute	Type	Default	Required	Introduction
  success	function		No	Callback function triggered when the API call successes
  fail	function		No	Callback function triggered when the API call fails

  Success callback function will receive an object with the following attributes:

  Attribute	Type	Introduction
  x	string	x-axis acceleration
  y	string	y-axis acceleration
  z	string	z-axis acceleration
  timestamp	string	Timestamp when the data was obtained

• Example

  const deviceManager = appGallery.getDeviceManager();
  
  // Get the current accelerometer data
  deviceManager.getCurrentAccelerometer({
    success(res) {
      console.log(res)
    },
    fail(err) {
      console.error(err.code)
      console.error(err.msg)
    },
  });
  

startAccelerometerListener

• Description

  Start accelerometer listener.

• Parameters

  Attribute	Type	Default	Required	Introduction
  interval	string	normal	No	Listen the execution frequency of the accelerometer data callback function. Valid values are: game, ui, normal. When an invalid value is passed, normal is used
  success	function		No	Callback function triggered when the accelerometer listener is successfully enabled
  fail	function		No	Callback function triggered when the API call fails

  The interval types are as follows:

  Valid Value	Introduction
  game	Applicable for updating game callback frequency, around 20ms per update
  ui	Applicable for updating UI callback frequency, around 60ms per update
  normal	Normal callback frequency, around 200ms per update

  Success callback function will receive an object with the following attributes:

  Attribute	Type	Introduction
  x	string	x-axis acceleration
  y	string	y-axis acceleration
  z	string	z-axis acceleration
  timestamp	string	Timestamp when the data was obtained

• Return

  Accelerometer listener ID

• Example

  const deviceManager = appGallery.getDeviceManager()
  
  // Start accelerometer listener
  const listenerId = deviceManager.startAccelerometerListener({
    interval: "ui",
    success(res) {
      console.log(res)
    },
    fail(err) {
      console.error(err.code)
      console.error(err.msg)
    },
  })
  

stopAccelerometerListener

• Description

  Stop specified or all accelerometer listeners.

• Parameters

  Attribute	Type	Default	Required	Introduction
  listenerId	string		No	Accelerometer listener ID. If listenerId or object parameter is not passed, all accelerometer listeners will be stopped

• Example

  const deviceManager = appGallery.getDeviceManager()
  
  // Method 1 :
  // Start accelerometer listener and record the corresponding listenerId
  const listenerId = deviceManager.startAccelerometerListener({
    interval: "game",
    success(res) {
      console.log(res)
    },
    fail(err) {
      console.error(err.code)
      console.error(err.msg)
    },
  })
  
  // Stop the accelerometer listener with the corresponding listenerId
  deviceManager.stopAccelerometerListener({
    listenerId: listenerId,
  })
  
  // Method 2 :
  // Start accelerometer listener, default as normal
  deviceManager.startAccelerometerListener({
    success(res) {
      console.log(res)
    },
    fail(err) {
      console.error(err.code)
      console.error(err.msg)
    },
  })
  
  // Stop all accelerometer listeners
  deviceManager.stopAccelerometerListener()
