Zend framework 没有ID为的设备使用Zend和WURFL

我已经将WURFL 1.6.0与Zend集成，一切都很顺利，它会检测到桌面，但在Android的情况下，我遇到了这个错误。深入研究后，我发现我的dir data/WURFL/cache没有加载任何数据，我授予了它777权限，但它仍然无法工作

$resourcesDir            = dirname(__FILE__) . '/../../data/wurfl/';

$wurfl['main-file']      = $resourcesDir  . 'wurfl.xml';
$wurfl['patches']        = array($resourcesDir . 'web_browsers_patch.xml');

$cache['provider']       = 'Null';
//
$persistence['provider'] = 'File';
$persistence['dir']      = $resourcesDir . '/cache/';


$configuration['wurfl']       = $wurfl;
$configuration['persistence'] = $persistence; 
$configuration['cache']       = $cache;

如果我给$cache['provider']=null；

---

它抛出了另一个异常。尝试使用$persistence['provider']='file'；但是没有用

从我可以看出，WURFL文件似乎没有被正确加载（可能是目录不可写）或者已经过时。您很可能需要删除持久性目录并重新加载WURFL API。

已经尝试过了。。。chmod 777，delete dir等没有任何功能，但问题是目录权限等
