Android JAVA $_FILE returms empty at files bigger than ~ 50 mb

Question

Problem: Trying to upload bigger than ~ 50 mb files, $_FILES return empty array.

I try change limits on php (a lot of combination) but it useleass..

my class at java:

    public void upload() throws Exception {

        HttpClient httpclient = new DefaultHttpClient();
        HttpPost httppost = new HttpPost(this.url);   

        try {

          FileBody bin = new FileBody(this.file);

          @SuppressWarnings("deprecation")
          MultipartEntity reqEntity = new MultipartEntity(HttpMultipartMode.BROWSER_COMPATIBLE);
          reqEntity.addPart("file", bin);
          httppost.setEntity(reqEntity);

          System.out.println("Requesting : " + httppost.getRequestLine());
          ResponseHandler<String> responseHandler = new BasicResponseHandler();

          String responseBody = httpclient.execute(httppost, responseHandler);

          System.out.println("responseBody : " + responseBody);

        } catch (UnsupportedEncodingException e) {
          e.printStackTrace();
        } catch (ClientProtocolException e) {
          e.printStackTrace();
        } catch (IOException e) {
          e.printStackTrace();
        } finally {
          httpclient.getConnectionManager().shutdown();
        }
    }

my php code to print array for respawn:

<?php
ini_set('file_uploads', 1);
ini_set('max_file_uploads', '9999999999M');
ini_set('post_max_size', '2000M');
ini_set('max_input_time', 3600);
ini_set('max_execution_time', 3600);


 print_r($_FILES);
?>

You could try to add the mime type of the file when you create the FileBody. For example:

FileBody bin = new FileBody(this.file, "application/octect-stream");

Another solution is to use the HttpURLConnection client that is easier to use and less error prone. Also, Google recommends to use it for new applications.

One side or the other is breaking the http connection being used by the POST action.

Do you know which side ( client or server )

If you do not know , maybe you should try to rule out the server by using CURL to do the M-Multipart Post of one of your big ( +50 ) files.

Invoke CURL to upload and add the -v switch for verbose log so you can analyse the process.

Android POST action on files of 50 - 100 meg should work fine.

Since you are doing big uploads , you would want a client that you can send headers "expect 100 Continue" and where you can employ chunked transfer encoding along with a client side thread that can provide data to a buffer that is wrapped by something like a byteArrayEntity

apache or nginX on std config should handle this fine. If your php process is abending then maybe you need to check phpinfo.
