    <p>I am an amateur in android coding. I am trying to setup an android app with the ability to download a file from an ftp server. While running the code on the android 2.2 emulator, i am able to connect to the ftp server but the downloading part is showing an error. LogCat gives "download failed".</p> <pre><code>package com.ftconnect.down; import java.io.FileOutputStream; import android.app.Activity; import android.os.Bundle; import android.util.Log; import org.apache.commons.net.ftp.*; public class FTPConnectActivity extends Activity { /** Called when the activity is first created. */ public FTPClient mFTPClient = null; public boolean mConnect; public boolean mDownload; public boolean mDisconnected; public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); mConnect = ftpConnect("xxx.xxx.xxx.xxx", "admin", "123456", 21); mDownload = ftpDownload("xxx.xxx.xxx.xxx/ftp.mp3", "/sdcard"); mDisconnected = ftpDisconnect(); } public boolean ftpConnect(String host, String username, String password, int port) { try { mFTPClient = new FTPClient(); // connecting to the host mFTPClient.connect(host, port); Log.d("ftpConnectApp", "Connecting to " + host); // now check the reply code, if positive mean connection success if (FTPReply.isPositiveCompletion(mFTPClient.getReplyCode())) { // login using username &amp; password boolean status = mFTPClient.login(username, password); return status; } } catch (Exception e) { Log.d("ftpConnectApp", "Error: could not connect to host " + host); } return false; } public boolean ftpDownload(String srcFilePath, String desFilePath) { boolean status = false; try { FileOutputStream desFileStream = new FileOutputStream(desFilePath); ; status = mFTPClient.retrieveFile(srcFilePath, desFileStream); desFileStream.close(); return status; } catch (Exception e) { Log.d("ftpConnectApp", "download failed"); } return status; } public boolean ftpDisconnect() { try { mFTPClient.logout(); mFTPClient.disconnect(); return true; } catch (Exception e) { Log.d("ftpConnectApp", "Error occurred while disconnecting from ftp server."); } return false; } } </code></pre> <p>I have setup the internet and write external permission in the android manifest file. Should i include any other permissions?</p> <p>Also, let me know if there is any changes to be made to the code above. Is the destination address as '/sdcard' correct?</p> <p>Thanks in advance.</p>

    3. CO@Jack: I've edited your code to remove the actual IP address - not sure if it's an actual address but you may not want to tell the world what it is (if you see what I mean). :D

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
