Does someone know how to listen to changes in that setting, with code similar or analogous to

Context context = configuration.getContext();
ContentResolver resolver = context.getContentResolver();
resolver.registerContentObserver(Settings.System.CONTENT_URI, true, observer = new TimeoutSettingContentObserver(context, new Handler()));

Here is the code:

PackageManager packageManager = getPackageManager(); 
final ApplicationInfo applicationInfo = packageManager.getApplicationInfo(getPackageName(), 0); 
appOpsManager = (AppOpsManager) getSystemService(Context.APP_OPS_SERVICE); 
appOpsManager.startWatchingMode(AppOpsManager.OPSTR_GET_USAG‌​E_STATS, 
        applicationInfo.packageName,
        new AppOpsManager.OnOpChangedListener(){ 
            @Override public void onOpChanged(String op, String packageName) {
                int mode = appOpsManager.checkOpNoThrow(op, applicationInfo.uid, packageName); 
                boolean enabled = mode == AppOpsManager.MODE_ALLOWED; 
            } 
        });
