I want to get the current angle of the foldable device. like ‘sensors-hal’

’sensors-hal’ log

I registered the ‘lid_angle_fusion’ sensor
and com.samsung.permission.SSENSOR permission error occurs.

My android manifest permission

    <uses-permission android:name="com.samsung.permission.SSENSOR"/>
    <uses-permission android:name="android.permission.SENSORS"/>

Register SensorManager

    private lateinit var mSensorManager: SensorManager
    private lateinit var mHingeAngleSensor: Sensor
    private var mSensorListener: SensorEventListener? = null

    private fun setupSensors() {
        mSensorManager = getSystemService(SENSOR_SERVICE) as SensorManager
        val sensorList: List<Sensor> = mSensorManager.getSensorList(Sensor.TYPE_ALL)
        for (sensor in sensorList) {
            if (sensor.name.contains("lid_angle_fusion")) {
                mHingeAngleSensor = sensor
            }
        }

        mSensorListener = object : SensorEventListener {
            override fun onSensorChanged(event: SensorEvent) {
                if (event.sensor == mHingeAngleSensor) {
                    val angle = event.values[0].toInt()
                }
            }

            override fun onAccuracyChanged(sensor: Sensor?, accuracy: Int) {
            }
        }
    }

    override fun onResume() {
        super.onResume()
        mSensorManager.registerListener(
            mSensorListener,
            mHingeAngleSensor,
            SensorManager.SENSOR_DELAY_FASTEST
        )
    }

Permission error

E/SensorService: ... Tried enabling a sensor (lid_angle_fusion  Wakeup) without holding com.samsung.permission.SSENSOR

How can I have com.samsung.permission.SSENSOR?

Or is there another way to know the current angle of the foldable device?

Hello,
I don’t think there is any other way to know the current angle of foldable devices. Regarding the com.samsung.permission.SSENSOR error, it is used for Samsung specific sensor which won’t be accessible by any third party application I guess.

Facing the same issue for accessing the grip sensor is there any solution i can solve this issue
com.example.sensordemo Tried enabling a sensor (SX9360 Grip sensor) without holding com.samsung.permission.SSENSOR
