HttpHostConnectException拒绝连接到http://192.168.1.33

My computer ip is 192.168.1.33. I want to access JOSN file returned by http://192.168.1.33//mla.php. I'm connecting my android phone,and I'm not using any emulators.I'm using AsyncTask to get data in SplashScreenActivity.I have changed apache's configuration file to allow all,even phpmyadmin page's configuration file to allow all devices.I'm parsing this URL in JSONParser class.How to access http://192.1638.1.33/mla.php rom my android phone?
