php - Can anyone help me capture an image, display it in imageView, store in gallery, upload that image to server? -

i want camera capture, image store in gallery, display in image view on screen , upload image server using php,json. have json parser code works. image gets saved as"temp" , gets overwritten(which don't want because want images in gallery) posting code below, please guide me.

public class camactivity extends activity  {           private imageview img;     int boundboxindp;     private static final int camera_request = 1888;      button bt1,bt2,btn;     contentvalues values;

the php code below

<?php  require("config.inc.php");  $target_path = "/uploads/"; $base=$_request['image']; $name=$_request['cmd']; echo $base; echo $name; // base64 encoded utf-8 string $binary=base64_decode($base); // binary, utf-8 bytes header('content-type: bitmap; charset=utf-8'); // print($binary); //$thefile = base64_decode($image_data); $file = fopen($target_path, 'wb'); $file = fopen($name, 'wb'); fwrite($file, $binary); fclose($file); //move_uploaded_file($file,$target_path.$name); copy($name,$target_path.$name);  ?> 

the problem in php code mistakenly override $file object

$file = fopen($target_path, 'wb'); $file = fopen($name, 'wb'); 

should replaced following:

$file = fopen($target_path.$name, 'wb'); 

you can append random number i.e using rand() or timestamp i.e. time() filename
