Start Activity from preferences.xml and get the result in onActivityResult

Try overriding startActivity() in your PreferencesActivity class and make it call startActivityForResult() instead after checking that the intent is the one we are interested in, similar to the following (with 1234 as the request code):

public class PreferencesActivity {
    // ...

    @Override
    public void startActivity(Intent intent) {
        if (thisIsTheExpected(intent)) {
            super.startActivityForResult(intent, 1234);
        } else {
            super.startActivity(intent);
        }
    }

    @Override
    protected void onActivityResult(int reqCode, int resCode, Intent data) {
        if (reqCode == 1234) {
            // should be getting called now
        }
    }

    // ...
}

Depending on your needs, this could be simpler compared to adding several OnPreferenceClickListener in your code :)
