How to open activity/fragment when SensorEventListener is triggered-CodePudding

I am trying to work with SensorEventListener, when phone shake is detected, I want to open a fragment GetInTouchMenuFragment through activity GetInTouchActivity

onCreate method of Activity is not called at all. so fragment is not shown.

this is my SensorEventListener in MainActivity.

MainActivity

override fun onCreate(savedInstanceState: Bundle?) {
 // Getting the Sensor Manager instance
        sensorManager = this.getSystemService(Context.SENSOR_SERVICE) as SensorManager

        Objects.requireNonNull(sensorManager)!!
            .registerListener(sensorListener, sensorManager!!
                .getDefaultSensor(Sensor.TYPE_ACCELEROMETER), SensorManager.SENSOR_DELAY_NORMAL)

}

private val sensorListener: SensorEventListener = object : SensorEventListener {
    override fun onSensorChanged(event: SensorEvent) {

        // Fetching x,y,z values
        val x = event.values[0]
        val y = event.values[1]
        val z = event.values[2]
        lastAcceleration = currentAcceleration

        // Getting current accelerations
        // with the help of fetched x,y,z values
        currentAcceleration = sqrt((x * x   y * y   z * z).toDouble()).toFloat()
        val delta: Float = currentAcceleration - lastAcceleration
        acceleration = acceleration * 0.9f   delta

        // Display a Toast message if
        // acceleration value is over 12
        if (acceleration > 12) {
            Log.d("GetInTouchActivity", "first")
            GetInTouchActivity.createIntent(this@MainActivity)
            Log.d("GetInTouchActivity", "second")
        }
    }
    override fun onAccuracyChanged(sensor: Sensor, accuracy: Int) {}
}

GetInTouchActivity

class GetInTouchActivity : InjectionFragmentActivity() {

    @Inject
    lateinit var viewModelFactory: ViewModelProvider.Factory

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.get_in_touch_activity)

        setAppBar(toolbar, showHomeAsUp = true, navIcon = AppBarNavIcon.BACK_ARROW_BLACK)

        if (savedInstanceState == null) {
        Log.d("GetInTouchActivity", "onCreate") // NOT EXECUTED
            showFragment(GetInTouchMenuFragment.newInstance())
        }
    }

    override fun onBackPressed() {
        reporter.reportEvent(javaClass.simpleName.processScreenName(), "Back")

        finish()
    }

    companion object {
        fun createIntent(context: Context): Intent {
            Log.d("GetInTouchActivity", "createIntent") // EXECUTED
            return Intent(context, GetInTouchActivity::class.java)
        }
    }
}

Could you please suggest what I am doing wrong here please, why onCreate in GetInTouchActivity is not called

Thank you for your assistance R

CodePudding user response：

where is your startActivity(..) call? :) its necessary to start new Activity, creating an Intent is not sufficient

val createdIntent = GetInTouchActivity.createIntent(this@MainActivity)
startActivity(createdIntent)
