I have an issue in save the value of progress of seek bar. I have two seek bar and have an one button and another one EditText widget. on click of button EditText seek bar value will be save in shared preferences, but on clicking it only save the EditTextvalue, not to save the value of seek bar. I try my best but its not working.My code is given below,
Profile2Activity.class
public class Profile2Activity extends Activity {
//TextViews to show details of volume and brightness
private TextView tVBrightness, tVVolume;
//SeekBars to set volume and brightness
private SeekBar sbVolume, sbBrightness;

private AudioManager audioManager;
//Variable to store brightness value
private int brightness;
//Content resolver used as a handle to the system's settings

private Window window;
