android upload images to server

Question

I am trying to upload images taken from phone camera to the server. Since I am new to uploading images in android I do not know much about this. I followed one tutorial on internet after googling which does work as a separat app but when I use that same class in my app it does not work anymore. I get errors in my logcat(which I will post at the end of this post). I do not know what does this error mean and how can I solve this. Please help me how can I make this work?

Here is my code for Camera activity

public class Camera extends Activity { ImageView ivUserImage; Button bUpload; Intent i; int CameraResult = 0; Bitmap bmp; FileUpload fu; @Override protected void onCreate(Bundle savedInstanceState) { // TODO Auto-generated method stub super.onCreate(savedInstanceState); setContentView(R.layout.camera); ivUserImage = (ImageView)findViewById(R.id.ivUserImage); bUpload = (Button)findViewById(R.id.bUpload); openCamera(); } private void openCamera() { i = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE); startActivityForResult(i, CameraResult); } @Override protected void onActivityResult(int requestCode, int resultCode, Intent data) { super.onActivityResult(requestCode, resultCode, data); if(resultCode == RESULT_OK) { Bundle extras = data.getExtras(); //Log.e("Image: ", data.toString()); bmp = (Bitmap) extras.get("data"); ivUserImage.setImageBitmap(bmp); bUpload.setOnClickListener(new View.OnClickListener() { public void onClick(View v) { // TODO Auto-generated method stub //Toast.makeText(getApplicationContext(), bmp.toString(), Toast.LENGTH_SHORT).show(); fu = new FileUpload(bmp.toString()); } }); } } }

Here is my FileUpload class

public class FileUpload extends Activity { TextView tv; Button b; int serverResponseCode = 0; ProgressDialog dialog = null; public FileUpload(final String bmp) { dialog = ProgressDialog.show(FileUpload.this, "", "Uploading file...", true); new Thread(new Runnable() { public void run() { runOnUiThread(new Runnable() { public void run() { tv.setText("uploading started....."); } }); int response= uploadFile(bmp); //Log.e("Response: ", response); System.out.println("RES : " + response); } }).start(); } public int uploadFile(String sourceFileUri) { String upLoadServerUri = "http://www.example.info/androidfileupload/index.php"; String fileName = sourceFileUri; HttpURLConnection conn = null; DataOutputStream dos = null; String lineEnd = "\r\n"; String twoHyphens = "--"; String boundary = "*****"; int bytesRead, bytesAvailable, bufferSize; byte[] buffer; int maxBufferSize = 1 * 1024 * 1024; File sourceFile = new File(sourceFileUri); if (!sourceFile.isFile()) { Log.e("uploadFile", "Source File Does not exist"); return 0; } try { // open a URL connection to the Servlet FileInputStream fileInputStream = new FileInputStream(sourceFile); URL url = new URL(upLoadServerUri); conn = (HttpURLConnection) url.openConnection(); // Open a HTTP connection to the URL conn.setDoInput(true); // Allow Inputs conn.setDoOutput(true); // Allow Outputs conn.setUseCaches(false); // Don't use a Cached Copy conn.setRequestMethod("POST"); conn.setRequestProperty("Connection", "Keep-Alive"); conn.setRequestProperty("ENCTYPE", "multipart/form-data"); conn.setRequestProperty("Content-Type", "multipart/form-data;boundary=" + boundary); conn.setRequestProperty("uploaded_file", fileName); dos = new DataOutputStream(conn.getOutputStream()); dos.writeBytes(twoHyphens + boundary + lineEnd); dos.writeBytes("Content-Disposition: form-data; name=\"uploaded_file\";filename=\""+ fileName + "\"" + lineEnd); dos.writeBytes(lineEnd); bytesAvailable = fileInputStream.available(); // create a buffer of maximum size bufferSize = Math.min(bytesAvailable, maxBufferSize); buffer = new byte[bufferSize]; // read file and write it into form... bytesRead = fileInputStream.read(buffer, 0, bufferSize); while (bytesRead > 0) { dos.write(buffer, 0, bufferSize); bytesAvailable = fileInputStream.available(); bufferSize = Math.min(bytesAvailable, maxBufferSize); bytesRead = fileInputStream.read(buffer, 0, bufferSize); } // send multipart form data necesssary after file data... dos.writeBytes(lineEnd); dos.writeBytes(twoHyphens + boundary + twoHyphens + lineEnd); // Responses from the server (code and message) serverResponseCode = conn.getResponseCode(); String serverResponseMessage = conn.getResponseMessage(); Log.i("uploadFile", "HTTP Response is : " + serverResponseMessage + ": " + serverResponseCode); if(serverResponseCode == 200){ runOnUiThread(new Runnable() { public void run() { tv.setText("File Upload Completed."); Toast.makeText(FileUpload.this, "File Upload Complete.", Toast.LENGTH_SHORT).show(); } }); } //close the streams // fileInputStream.close(); dos.flush(); dos.close(); } catch (MalformedURLException ex) { dialog.dismiss(); ex.printStackTrace(); Toast.makeText(FileUpload.this, "MalformedURLException", Toast.LENGTH_SHORT).show(); Log.e("Upload file to server", "error: " + ex.getMessage(), ex); } catch (Exception e) { dialog.dismiss(); e.printStackTrace(); Toast.makeText(FileUpload.this, "Exception : " + e.getMessage(), Toast.LENGTH_SHORT).show(); Log.e("Upload file to server Exception", "Exception : " + e.getMessage(), e); } dialog.dismiss(); return serverResponseCode;

} }

and here is what I get in my logcat

Have you set all the required permissions in your Android Mainifest? — libjup

I think it requires '<uses-permission android:name="android.permission.INTERNET"/> ' internet permission which I did — Om3ga

you pass Context from your main Activity to this Upload class. — Md Abdul Gafur

You create Object FileUpload activity using new. In Android, an activity is suggested to be designed as a standalone module, and the activity is created by Android. If you want to communicate to other activities, you should use Intent to do this.

fu = new FileUpload(bmp.toString()); // here make error.

In android it is not possible to create object of another activity.

Yeah I do not want this class to be an activity. I wanted to make a complete new class i.e. class FileUpload { }. But when I changed it showed tons of errors. I mean there were so many line red underline.

public FileUpload(Context context, final String bmp) { dialog = ProgressDialog.show(context, "", "Uploading file...", true); new Thread(new Runnable() { public void run() { runOnUiThread(new Runnable() { public void run() { tv.setText("uploading started....."); } }); int response= uploadFile(bmp); //Log.e("Response: ", response); System.out.println("RES : " + response); } }).start(); } and fu = new FileUpload(this, bmp.toString());

I recommend you to create a FTP server and use ftp for Uploading your files. the following code is a method for getting file from FTP server. customize it for uploading:

public static boolean getFile(String serverName, String userName, String password, String serverFilePath, String localFilePath) throws Exception { FTPClient ftp = new FTPClient(); try { // ftp.setCopyStreamListener(); ftp.connect(serverName); int reply = ftp.getReplyCode(); if (!FTPReply.isPositiveCompletion(reply)) { ftp.disconnect(); return false; } } catch (IOException e) { if (ftp.isConnected()) { try { ftp.disconnect(); } catch (IOException f) { throw e; } } throw e; } catch (Exception e) { throw e; } try { // String filePath = "system/mswin.98/SETUP0.WAV"; if (!ftp.login(userName, password)) { ftp.logout(); } // if (binaryTransfer) ftp.setFileType(FTPClient.BINARY_FILE_TYPE); // ftp.enterLocalPassiveMode(); ftp.enterLocalActiveMode(); OutputStream output; if (checkAndCreateDirectories(localFilePath)) { output = new FileOutputStream(localFilePath); ftp.retrieveFile(serverFilePath, output); output.close(); } ftp.noop(); // check that control connection is working OK ftp.logout(); return true; } catch (FTPConnectionClosedException e) { throw e; } catch (IOException e) { throw e; } catch (Exception e) { throw e; } finally { if (ftp.isConnected()) { try { ftp.disconnect(); } catch (IOException f) { throw f; } } } }
