Uploading file from android (java) to server using PHP

Question

Hello Im trying to upload files from my android application to my server using PHP.

I have read this posts:

How to upload a file using Java HttpClient library working with PHP http://www.veereshr.com/Java/Upload How do I send a file in Android from a mobile device to server using http?

This is my JAVA code:

public void upload() throws Exception {

        File file = new File("data/data/com.tigo/databases/exercise");

        Log.i("file.getName()", file.getName());

        HttpClient httpclient = new DefaultHttpClient();
        HttpPost httppost = new HttpPost("http://***.***.***.***/backDatabase.php");

        InputStreamEntity reqEntity = new InputStreamEntity( new FileInputStream(file), -1);
        reqEntity.setContentType("binary/octet-stream");    

        reqEntity.setChunked(true);
        httppost.setEntity(reqEntity);
        HttpResponse response = httpclient.execute(httppost);

        if((response.getStatusLine().toString()).equals("HTTP/1.1 200 OK")){
            // Successfully Uploaded
            Log.i("uploaded", response.getStatusLine().toString());
        }
        else{
            // Did not upload. Add your logic here. Maybe you want to retry.
            Log.i(" not uploaded", response.getStatusLine().toString());
        }

        httpclient.getConnectionManager().shutdown();
    }

This is my PHP code:

<?php


    $uploads_dir = '/tigo/databaseBackup';

    if (is_uploaded_file($_FILES['exercise']['tmp_name']))
    {

    $info =  "File ". $_FILES['exercise']['name'] ." uploaded successfully.\n";
    $file = 'emailTest.log';
    file_put_contents($file, $info, FILE_APPEND | LOCK_EX);

    move_uploaded_file ($_FILES['exercise'] ['tmp_name'], $_FILES['exercise'] ['name']);

    } 
    else 
    {

    $info =  "Possible file upload attack: ";
    $file = 'emailTest.log';
    file_put_contents($file, $info, FILE_APPEND | LOCK_EX);

    $info =  "filename '". $_FILES['exercise']['tmp_name'] . "'.";
    file_put_contents($file, $info, FILE_APPEND | LOCK_EX);

    print_r($_FILES);

    }

?>

In my logcat i get HTTP/1.1 200 OK. When i look at the server logs i get this error:

PHP Notice:  Undefined index: exercise in /var/www/backDatabase.php on line 23

I also tried to use:

$_FILES['userfile']['name']

Instead of

$_FILES['exercise']['tmp_name']

And i got the same error in my server logs.

I think my problem is that I cant get reference to my uploaded file.

Thanks for helping.

try multipart entity

public void upload(String filepath) throws IOException
    {
     HttpClient httpclient = new DefaultHttpClient();
     httpclient.getParams().setParameter(CoreProtocolPNames.PROTOCOL_VERSION, HttpVersion.HTTP_1_1);
     HttpPost httppost = new HttpPost("url");
     File file = new File(filepath);
     MultipartEntity mpEntity = new MultipartEntity();
     ContentBody cbFile = new FileBody(file, "image/jpeg");
     mpEntity.addPart("userfile", cbFile); 
     httppost.setEntity(mpEntity);
     System.out.println("executing request " + httppost.getRequestLine());
     HttpResponse response = httpclient.execute(httppost);
     HttpEntity resEntity = response.getEntity();
             // check the response and do what is required
      }
