- by Shashank_Itmaster

Hello All, I stuck in middle of this situation,Please help me out. My question is that I want to send files (Total 11 PDF Files) to android app using web service. I tried it with below code.Main Class from which web service is created public class MultipleFilesImpl implements MultipleFiles { public FileData[] sendPDFs() { FileData fileData = null; // List<FileData> filesDetails = new ArrayList<FileData>(); File fileFolder = new File( "C:/eclipse/workspace/AIPWebService/src/pdfs/"); // File fileTwo = new File( // "C:/eclipse/workspace/AIPWebService/src/simple.pdf"); File sendFiles[] = fileFolder.listFiles(); // sendFiles[0] = fileOne; // sendFiles[1] = fileTwo; DataHandler handler = null; char[] readLine = null; byte[] data = null; int offset = 0; int numRead = 0; InputStream stream = null; FileOutputStream outputStream = null; FileData[] filesData = null; try { System.out.println("Web Service Called Successfully"); for (int i = 0; i < sendFiles.length; i++) { handler = new DataHandler(new FileDataSource(sendFiles[i])); fileData = new FileData(); data = new byte[(int) sendFiles[i].length()]; stream = handler.getInputStream(); while (offset < data.length && (numRead = stream.read(data, offset, data.length - offset)) >= 0) { offset += numRead; } readLine = Base64Coder.encode(data); offset = 0; numRead = 0; System.out.println("'Reading File............................"); System.out.println("\n"); System.out.println(readLine); System.out.println("Data Reading Successful"); fileData.setFileName(sendFiles[i].getName()); fileData.setFileData(String.valueOf(readLine)); readLine = null; System.out.println("Data from bean " + fileData.getFileData()); outputStream = new FileOutputStream("D:/" + sendFiles[i].getName()); outputStream.write(Base64Coder.decode(fileData.getFileData())); outputStream.flush(); outputStream.close(); stream.close(); // FileData fileDetails = new FileData(); // fileDetails = fileData; // filesDetails.add(fileData); filesData = new FileData[(int) sendFiles[i].length()]; } // return fileData; } catch (FileNotFoundException e) { e.printStackTrace(); } catch (IOException e) { e.printStackTrace(); } catch (Exception e) { e.printStackTrace(); } return filesData; } } Also The Interface MultipleFiles:- public interface MultipleFiles extends Remote { public FileData[] sendPDFs() throws FileNotFoundException, IOException, Exception; } Here I am sending an array of bean "File Data",having properties viz. FileData & FileName. FileData- contains file data in encoded. FileName- encoded file name. The Bean:- (FileData) public class FileData { private String fileName; private String fileData; public String getFileName() { return fileName; } public void setFileName(String fileName) { this.fileName = fileName; } public String getFileData() { return fileData; } public void setFileData(String string) { this.fileData = string; } } The android DDMS gives out of memory exception when tried below code & when i tried to send two files then only first file is created. public class PDFActivity extends Activity { private final String METHOD_NAME = "sendPDFs"; private final String NAMESPACE = "http://webservice.uks.com/"; private final String SOAP_ACTION = NAMESPACE + METHOD_NAME; private final String URL = "http://192.168.1.123:8080/AIPWebService/services/MultipleFilesImpl"; /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); TextView textViewOne = (TextView) findViewById(R.id.textViewOne); try { SoapObject soapObject = new SoapObject(NAMESPACE, METHOD_NAME); SoapSerializationEnvelope envelope = new SoapSerializationEnvelope( SoapEnvelope.VER11); envelope.setOutputSoapObject(soapObject); textViewOne.setText("Web Service Started"); AndroidHttpTransport httpTransport = new AndroidHttpTransport(URL); httpTransport.call(SOAP_ACTION, envelope); // SoapObject result = (SoapObject) envelope.getResponse(); Object result = envelope.getResponse(); Log.i("Result", result.toString()); // String fileName = result.getProperty("fileName").toString(); // String fileData = result.getProperty("fileData").toString(); // Log.i("File Name", fileName); // Log.i("File Data", fileData); // File pdfFile = new File(fileName); // FileOutputStream outputStream = // openFileOutput(pdfFile.toString(), // MODE_PRIVATE); // outputStream.write(Base64Coder.decode(fileData)); Log.i("File", "File Created"); // textViewTwo.setText(result); // Object result = envelope.getResponse(); // FileOutputStream outputStream = openFileOutput(name, mode) } catch (Exception e) { e.printStackTrace(); } } } Please help with some explanation or changes in my code. Thanks in Advance.
