override fun init_events() {
  

        sensoreManager=getSystemService(Context.SENSOR_SERVICE) as SensorManager
        if(sensoreManager!!.getDefaultSensor(Sensor.TYPE_STEP_COUNTER)!=null)
        {

            sensor=sensoreManager!!.getDefaultSensor(Sensor.TYPE_STEP_COUNTER)
            running=true
            showToastMessage("yes")

           showToastMessage("no")
            running=false
        }

    override fun onAccuracyChanged(sensor: Sensor?, accuracy: Int) {
        Log.i("TEST_TEST","ssssssssssss")
       
    }

    @SuppressLint("SetTextI18n")
    override fun onSensorChanged(event: SensorEvent?) {
        Log.i("TEST_TEST","ssssssssssss")

    override fun onResume() {
        Log.i("TEST_TEST","f RESume")

        super.onResume()
        if(sensoreManager!!.getDefaultSensor(Sensor.TYPE_STEP_COUNTER)!=null){
            sensoreManager!!.registerListener(this,sensor,SensorManager.SENSOR_DELAY_FASTEST)
            Log.i("TEST_TEST","not null")}
        else{
            Log.i("TEST_TEST","null")
        }
    }

    override fun onPause() {
        Log.i("TEST_TEST","f onPause")
        super.onPause()
        if(sensoreManager!!.getDefaultSensor(Sensor.TYPE_STEP_COUNTER)!=null)
           sensoreManager!!.unregisterListener(this,sensor)
    }

what wrong on this code my device xiaomi note 9 pro

Answer 1

the anser in this code you have to accept permission in android 10

if(ContextCompat.checkSelfPermission(this,
            Manifest.permission.ACTIVITY_RECOGNITION) == PackageManager.PERMISSION_DENIED){
        //ask for permission
        requestPermissions(new String[]{Manifest.permission.ACTIVITY_RECOGNITION}, PHYISCAL_ACTIVITY);
    }
    ```
