    var ownedPermission = function() {
      // done
      callback && callback();
    };

    var requestStoragePerm = function() {
      if (!RSP.hasStoragePermission()) {
        RSP.requestStoragePermissions(function (e) {
          if (e.success) {
            // success
            Ti.API.info('requestStoragePermission : success');
            ownedPermission();
          } else {
            // retry or settings open
            Ti.API.error('requestStoragePermission : error');
            var dialog = Ti.UI.createAlertDialog({
              message: msg,
              cancel: 1,
              buttonNames: ["OK", "Open Setting"],
              title: "Need Storeage Permission"
            });
            dialog.addEventListener('click', function(e){
              if (e.index === e.source.cancel){
                Ti.API.debug('settings open');
                var resumedFn = function() {
                  requestStoragePerm();
                  Ti.Android.currentActivity.onStart = null;
                  Ti.Android.currentActivity.onResume = null;
                };
                Ti.Android.currentActivity.onStart = resumedFn;
                Ti.Android.currentActivity.onResume = resumedFn;

                // settings open
                RSP.settingsOpen();
              } else {
