I have an app in Android witch takes a picture and needs to upolad it to a server with php.

At first there was no problem, I was able to upload it, but now I need to pass the path where the picture will be uploaded to the server. The problems comes when I try to send two values.

I am using the following code:

private void httpPostFileUpload(String fpath, String uPath){ HttpURLConnection connection = null; DataOutputStream outputStream = null; DataInputStream inputStream = null; //Path where to upload String uploadPath = uPath; String pathToOurFile = fpath; Log.v("file path",fpath.toString()); String urlServer = "http://leojg.alwaysdata.net/tests/androidConnect/handle_upload.php"; String lineEnd = "\r\n"; String twoHyphens = "--"; String boundary = "*****"; String fname = ""; int bytesRead, bytesAvailable, bufferSize; byte[] buffer; int maxBufferSize = 1*1024*1024; try { File f = new File(pathToOurFile); fname = f.getName(); FileInputStream fileInputStream = new FileInputStream(f); URL url = new URL(urlServer); connection = (HttpURLConnection) url.openConnection(); // Allow Inputs & Outputs connection.setDoInput(true); connection.setDoOutput(true); connection.setUseCaches(false); // Enable POST method connection.setRequestMethod("POST"); connection.setRequestProperty("Connection", "Keep-Alive"); connection.setRequestProperty("Content-Type", "multipart/form-data;boundary="+boundary); outputStream = new DataOutputStream( connection.getOutputStream() ); outputStream.writeBytes(twoHyphens + boundary + lineEnd); Log.d("path file", pathToOurFile); Log.d("path up", uploadPath); outputStream.writeBytes("Content-Disposition: form-data; name=\"uploadedfile\";filename=\"" + pathToOurFile + "\"" + lineEnd); outputStream.writeBytes(lineEnd); bytesAvailable = fileInputStream.available(); bufferSize = Math.min(bytesAvailable, maxBufferSize); buffer = new byte[bufferSize]; // Read file bytesRead = fileInputStream.read(buffer, 0, bufferSize); while (bytesRead > 0) { outputStream.write(buffer, 0, bufferSize); bytesAvailable = fileInputStream.available(); bufferSize = Math.min(bytesAvailable, maxBufferSize); bytesRead = fileInputStream.read(buffer, 0, bufferSize); } outputStream.writeBytes(lineEnd); outputStream.writeBytes(twoHyphens + boundary + twoHyphens + lineEnd); // Responses from the server (code and message) int serverResponseCode = connection.getResponseCode(); String serverResponseMessage = connection.getResponseMessage(); Log.d("amanda", "upload async finished, server response : " + serverResponseMessage); fileInputStream.close(); fileInputStream = null; outputStream.flush(); outputStream.close(); outputStream = null; f= null; parent.invokeJs("pictureUploadEnded('" + fname + "')"); this.delete(fpath); } catch (Exception ex) { Log.d("amanda", "exception uploading image : " + ex.getMessage()); } }

I am pretty sure that the problem is in this line

outputStream.writeBytes("Content-Disposition: form-data; name=\"uploadedfile\";filename=\"" + pathToOurFile + "\"" + lineEnd);

Which is the one that makes the post body. I dont know where to attrach uploadPath

Well following Class work for me :

import java.io.DataOutputStream; import java.io.File; import java.io.FileInputStream; import java.io.IOException; import java.io.InputStream; import java.net.HttpURLConnection; import java.net.MalformedURLException; import java.net.URL; import org.json.JSONException; import org.json.JSONObject; import org.json.JSONTokener; import android.os.Environment; import android.util.Log; public class HttpPictureUpload implements Runnable { private String TAG = "HTTPFILEUPLOAD"; private URL connectURL; private FileInputStream fileInputStream = null; private String pictureFileName; private String myName; public HttpPictureUpload(String urlString, String pictureFileNameString, String myNameString) { try { connectURL = new URL(urlString); pictureFileName = pictureFileNameString; myName = myNameString; } catch (Exception ex) { Log.i(TAG, "URL Malformatted"); } } public void SendPictureNow() { Sending(); } private void Sending() { int maxBufferSize = 1 * 1024*1024*1024; String lineEnd = "\r\n"; String twoHyphens = "--"; String boundary = "*****"; try { fileInputStream = new FileInputStream(Environment .getExternalStorageDirectory().toString() + "/Picture/" + pictureFileName); Log.e(TAG, "Starting Http File Sending to URL"); // Open a HTTP connection to the URL HttpURLConnection conn = (HttpURLConnection) connectURL .openConnection(); conn.setChunkedStreamingMode(maxBufferSize); // conn.setchu // 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()); // sending appid dos.writeBytes(twoHyphens + boundary + lineEnd); dos.writeBytes("Content-Disposition: form-data; name=\"my_name\"" + lineEnd); dos.writeBytes(lineEnd); dos.writeBytes(myName); dos.writeBytes(lineEnd); dos.writeBytes(twoHyphens + boundary + lineEnd); dos.writeBytes("Content-Disposition: form-data; name=\"file\";filename=\"" + System.currentTimeMillis() + "\"" + lineEnd); dos.writeBytes(lineEnd); int bytesAvailable = fileInputStream.available(); byte[] buffer = new byte[bytesAvailable]; 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); } dos.writeBytes(lineEnd); dos.writeBytes(twoHyphens + boundary + twoHyphens + lineEnd); fileInputStream.close(); dos.flush(); Log.e(TAG, "File Sent, Response: " + String.valueOf(conn.getResponseCode())); InputStream is = conn.getInputStream(); // retrieve the response from server int ch; StringBuffer b = new StringBuffer(); while ((ch = is.read()) != -1) { b.append((char) ch); } String s = b.toString(); Log.i("Response", s); dos.close(); } catch (MalformedURLException ex) { Log.e(TAG, "URL error: " + ex.getMessage(), ex); } catch (IOException ioe) { Log.e(TAG, "IO error: " + ioe.getMessage(), ioe); } } @Override public void run() { // TODO Auto-generated method stub } }

Above class can be use to send picture file or any other file and one any string.
To use above : 

HttpPictureUpload uploadPicture=new HttpPictureUpload("http://serverurl.com/webservice.php", "tux.png", "my name is john"); uploadPicture.SendPictureNow();
