Android file uploader with server-side php

I've been looking for a solution to this for hours, but I can't find any.

Basically, I want to upload, from my android device, files to an http website. However, I have no clue whatsoever how to do this. I'm using java on the device, and I would like to use PHP on the server-side of things. I just want to upload the files, not do anything fancy with them on the server.

Can anyone provide code and/or a good link to what I need? I have little to no experience in this, and I am at a loss.

Thanks, NS

PS. I have no experience in PHP coding.

Yeah, so I found the java-side of things. This works, so... yeah.

public class Uploader extends Activity {

    private String Tag = "UPLOADER";
    private String urlString = "YOUR_ONLINE_PHP";
    HttpURLConnection conn;

    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        String exsistingFileName = "/sdcard/uploader/data/testfile";

        String lineEnd = "\r\n";
        String twoHyphens = "--";
        String boundary = "*****";
        try {
            // ------------------ CLIENT REQUEST

            Log.e(Tag, "Inside second Method");

            FileInputStream fileInputStream = new FileInputStream(new File(
                    exsistingFileName));

            // open a URL connection to the Servlet

            URL url = new URL(urlString);

            // Open a HTTP connection to the URL

            conn = (HttpURLConnection) url.openConnection();

            // Allow Inputs
            conn.setDoInput(true);

            // Allow Outputs
            conn.setDoOutput(true);

            // Don't use a cached copy.
            conn.setUseCaches(false);

            // Use a post method.
            conn.setRequestMethod("POST");

            conn.setRequestProperty("Connection", "Keep-Alive");

            conn.setRequestProperty("Content-Type",
                    "multipart/form-data;boundary=" + boundary);

            DataOutputStream dos = new DataOutputStream(conn.getOutputStream());

            dos.writeBytes(twoHyphens + boundary + lineEnd);
            dos
                    .writeBytes("Content-Disposition: post-data; name=uploadedfile;filename="
                            + exsistingFileName + "" + lineEnd);
            dos.writeBytes(lineEnd);

            Log.e(Tag, "Headers are written");

            // create a buffer of maximum size

            int bytesAvailable = fileInputStream.available();
            int maxBufferSize = 1000;
            // int bufferSize = Math.min(bytesAvailable, maxBufferSize);
            byte[] buffer = new byte[bytesAvailable];

            // read file and write it into form...

            int bytesRead = fileInputStream.read(buffer, 0, bytesAvailable);

            while (bytesRead > 0) {
                dos.write(buffer, 0, bytesAvailable);
                bytesAvailable = fileInputStream.available();
                bytesAvailable = Math.min(bytesAvailable, maxBufferSize);
                bytesRead = fileInputStream.read(buffer, 0, bytesAvailable);
            }

            // send multipart form data necesssary after file data...

            dos.writeBytes(lineEnd);
            dos.writeBytes(twoHyphens + boundary + twoHyphens + lineEnd);

            // close streams
            Log.e(Tag, "File is written");
            fileInputStream.close();
            dos.flush();
            dos.close();

        } catch (MalformedURLException ex) {
            Log.e(Tag, "error: " + ex.getMessage(), ex);
        }

        catch (IOException ioe) {
            Log.e(Tag, "error: " + ioe.getMessage(), ioe);
        }

        try {
            BufferedReader rd = new BufferedReader(new InputStreamReader(conn
                    .getInputStream()));
            String line;
            while ((line = rd.readLine()) != null) {
                Log.e("Dialoge Box", "Message: " + line);
            }
            rd.close();

        } catch (IOException ioex) {
            Log.e("MediaPlayer", "error: " + ioex.getMessage(), ioex);
        }
    }
}

If you want to upload files that is larger than 2MB you need to edit your PHP configuraton

; Maximum allowed size for uploaded files.
; http://php.net/upload-max-filesize
upload_max_filesize = 2M

Eg:

; Maximum allowed size for uploaded files.
; http://php.net/upload-max-filesize
upload_max_filesize = 10M

That would allow you to upload files up to 10MB of size

For the PHP side of things take a look at

move_uploaded_file and also the global $_FILES
