        if (packageInfo.installLocation == PackageInfo.INSTALL_LOCATION_AUTO) {
            //Log.i(TAG, "INSTALL_LOCATION_AUTO");
            return true;
        } else if (packageInfo.installLocation == PackageInfo.INSTALL_LOCATION_PREFER_EXTERNAL) {
            //Log.d(TAG, "INSTALL_LOCATION_PREFER_EXTERNAL");
            return true;
        } else {
