Question

I have created a PreferenceScreen with a few checkboxes.

One of them is:

 <CheckBoxPreference
            android:title="Show facebook popup"
            android:defaultValue="true"
            android:summary="Share Your score on facebook"
            android:key="showFbCheck"/>

I want to update this CheckBox from another activity, How this can be achieved?

So long as the two activities are in the same application, you simply tell the other activity load the sharedPreferences with the same KEY that your preference activity uses. There’s a whole page on preferences in the SDK:
