upload file to php script on background
<p>i want to upload a file (picture) to the server (PHP script), but in background. I am searching a very lightweight AsyncTask to do this, but i can't find any usefull on google.</p>

<p>Any Idea how i can upload a file to PHP with an AsyncTask? The upload Fucntion should only get the local file as variable, every else shoudl be not variable...</p>

<p>Maybe somebody can help me with that?</p>
