How to get light sensor value

I have following code uses light sensor but not able to display value of event.value[0]...it displays toast only with message "On SensorChanged" also text is not set to tv where i goes wrong..

here is code

    public void onSensorChanged(SensorEvent event) 
    {
    if( event.sensor.getType() == Sensor.TYPE_LIGHT)
    {
        tv.setText("value: " + event.values[0] + " lux" );   
        Toast.makeText(getApplicationContext(),"On SensorChanged"+ event.values[0],Toast.LENGTH_SHORT).show();
        Log.d("Sensor Changed", "onSensor Change :" + brightness);
    }

}
Solution

  • I dont think that is contains light sensors to that why it is returning nothing,your code seems fine otherwise,
