when upload button clicked then, toast image uploaded image file not received @ php.

the php code shown below :

    <?php         $name = $_post["name"];         $image = $_post["image"]; $decodedimage = base64_decode("$image");         file_put_contents("rohit/" . $name . ".jpg",$decodedimage);     ?> 

what might have gone wrong ?

chang

string serveraddress = "http://localhost";

to

string serveraddress = "http://10.0.2.2";

for emulator,

change machine ip when using on phone on lan
