I'm trying to write a file and upload it, however, the file does not seem to be written properly (as later on that I need to upload it, it crashes and says no file). I'm following the guidelines of Google's documentation. Here's my code:
String fileLocation = "Hello"; String TESTSTRING = new String("Hello Android"); FileOutputStream fOut = openFileOutput(fileLocation, MODE_WORLD_READABLE); fOut.write(TESTSTRING.getBytes()); fOut.close(); That's how I'm trying to upload:
HttpURLConnection connection = null; DataOutputStream outputStream = null; DataInputStream inputStream = null; String pathToOurFile = fileLocation; String Tag = "UPLOADER"; HttpURLConnection conn = null; String urlServer = "http://..."; //my server String lineEnd = "\r\n"; String twoHyphens = "--"; String boundary = "*****"; try { // ------------------ CLIENT REQUEST Log.e(Tag, "Inside second Method"); FileInputStream fileInputStream = new FileInputStream(new File(fileLocation)); // open a URL connection to the Servlet URL url = new URL(urlServer); // 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=" + fileLocation + "" + 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); } } Here's the PHP code on the server:
$target_path = "./"; $target_path = $target_path . basename( $_FILES['uploadedfile']['name']); if(move_uploaded_file($_FILES['uploadedfile']['tmp_name'], $target_path)) { echo "The file ". basename( $_FILES['uploadedfile']['name']). " has been uploaded"; } else{ echo "There was an error uploading the file, please try again!"; } 
fileLocationstring as the file name later for uploading it.
