Question

I have 2 Fragments. 1st is for calculation while the 2nd is for settings.

I save the settings using SharedPreference.Editor.commit() on onPause() method. No problem so far with the saving. The problem I am facing is retrieving the SharedPreference value on my 1st Fragment. I retrieved the value every time I pressed the count button. For the 1st time, the values I am getting are the ones before change (which is the problem I am facing), I will only get my saved value when retrieving/pressing the count button for the 2nd time or more.

And I try to change the settings and then press home button to terminate the app from outside (which triggers onPause method) and when I reopened the settings, the values did change to my defined settings. So, I am sure the settings did saved when onPause is triggered.

I wonder what is going wrong here. Any helps is much appreciated.

As requested, this is my saving code on my SettingFragment :

@Override
public void onPause() {
        super.onPause();
        saveToPref();
    }

public void saveToPref() {
        SharedPreferences settings = getActivity().getSharedPreferences("mysettings", 0);
        Editor edit = settings.edit();
        edit.putString("begin", String.valueOf(ibegin)).putString("end", String.valueOf(iend)).commit();
    }

Ok, I have found my problem. The problem is that onPause() is triggered only when I start another activity (I started an activity onClick of Button count). I changed my code to trigger the saveToPref() by overriding onPageSelected of my ViewPager and on backPressed of my MainActivity.
