PHP side i used smarty framework
$print = false;
$header = true;
if(isset($_REQUEST['action']) && $_REQUEST['action'] =='imagetest')
{
$error = '0';
$val = basename($_FILES['image']['name']);
if($val != '')
{
$error = '1';
$msg = 'Image Not Upload Please Try Agin';
$param = array("status"=>"error","msg"=>$val);
$val = json_encode($param);
echo $val;
exit;
}
/*if($_FILES['image'] == '')
{
$error = '1';
$msg = 'Image Not Upload Please Try Agin';
$param = array("status"=>"error","msg"=>$msg);
$val = json_encode($param);
echo $val;
exit;
}*/
if($error == '0')
{
$target_path = "uploads/";
$target_path = $target_path . basename( $_FILES['image']['name']);
if(move_uploaded_file($_FILES['image']['tmp_name'], $target_path)) {
$msg = 'Image inserted successfully';
$param = array("status"=>"success","msg"=>$msg);
$val = json_encode($param);
echo $val;
exit;
} else{
$msg = 'Image not inserted successfully';

回答1:
you can refer this nice tutorial "Android Uploading Camera Image, Video to Server with Progress Bar"
回答2:
Try specifying the length of the file in the header. It seems some servers may reject the file if there is no Content-Length header. E.g.:
conn.setRequestProperty("Content-Length", Integer.toString(fileInputStream.available()));
