How to add default Widget in customised Android Home Screen?

I use Launcher2 home screen as the basis for customised the home screen. I wanted to customized Android Home Screen with default Widget.

But when I use this example, I get this error:

I've already added android.permission.BIND_APPWIDGET in my manifest, but it's still not working and my default widget is still missing.

Does anyone have any idea what could be the problem?

android.permission.BIND_APPWIDGET is not available for applications outside of system storage.

Without a full stack trace I cannot pinpoint the exact location of the error but this is what I expect is causing the problem.

void addAppWidget(Intent data) {
        int appWidgetId = data.getIntExtra(AppWidgetManager.EXTRA_APPWIDGET_ID, -1);
        AppWidgetProviderInfo appWidget = mAppWidgetManager.getAppWidgetInfo(appWidgetId);

        if (appWidget.configure != null) {
            // Launch over to configure widget, if needed
            Intent intent = new Intent(AppWidgetManager.ACTION_APPWIDGET_CONFIGURE);
            intent.setComponent(appWidget.configure);
            intent.putExtra(AppWidgetManager.EXTRA_APPWIDGET_ID, appWidgetId);

            startActivityForResultSafely(intent, REQUEST_CREATE_APPWIDGET);
        } else {
            // Otherwise just add it
            onActivityResult(REQUEST_CREATE_APPWIDGET, Activity.RESULT_OK, data);
        }
}
