How can i cancel running download file?

I want to cancel currently download file from notification area & I want to add cancel button at the bottom of notification download progress. By clicking on that cancel button, download should be cancel. Here is my class DownloadSong using which I perform download file. What modifications I need to do?
public class DownloadSong extends AsyncTask<String, Integer, String> {
Activity activity;
public static String songName, songURL;
private NotificationHelper mNotificationHelper;
public static int notificationID = 1;
boolean download = false;
NotificationManager nm;
public DownloadSong(Activity activity, String songName, String songURL) {
this.activity = activity;
this.songName = songName;
this.songURL = songURL;
mNotificationHelper = new NotificationHelper(activity, songName);
}
#Override
protected void onPreExecute() {
super.onPreExecute();
notificationID++;
mNotificationHelper.createNotification(notificationID);
}
#Override
protected String doInBackground(String... file_URL) {
try {
URL url = new URL(songURL);
HttpURLConnection URLconnection = (HttpURLConnection) url.openConnection();
URLconnection.setRequestMethod("GET");
URLconnection.setDoOutput(true);
URLconnection.connect();
// Detect the file length
int fileLength = URLconnection.getContentLength();
File fSDcard = Environment.getExternalStorageDirectory();
String strSdcardPath = fSDcard.getAbsolutePath();
File fDirectory = new File(strSdcardPath + "/GSD");
if (!fDirectory.exists()) {
fDirectory.mkdir();
}
File fMyFile = new File(fDirectory.getAbsolutePath() + "/" + songName + ".mp3");
Log.e("Download file name ", fMyFile.toString());
FileOutputStream out = new FileOutputStream(fMyFile, true);
InputStream input_File = URLconnection.getInputStream();
byte[] data = new byte[1024];
int total = 0;
int count;
while ((count = input_File.read(data)) != -1) {
total += count;
publishProgress((int) (total * 100 / fileLength));
out.write(data, 0, count);
}
out.flush();
out.close();
input_File.close();
} catch (IOException e) {
Log.e("Download Error : ", "Failed");
}
Log.e("Download status", " Complete ");
return null;
}
#Override
protected void onPostExecute(String s) {
Toast.makeText(activity, "Song " + "'" + songName + "'" + " downloaded successfully", Toast.LENGTH_LONG).show();
//pDialog.dismiss();
if (download) {
Toast.makeText(activity, "Could Not Connect to Server.", Toast.LENGTH_LONG).show();
mNotificationHelper.clearNotification();
} else
mNotificationHelper.completed();
}
#Override
protected void onProgressUpdate(Integer... progress) {
//pDialog.setProgress(progress[0]);
mNotificationHelper.progressUpdate(progress[0]);
super.onProgressUpdate(progress);
}
}

Most of the time is spent in the loop
while ((count = input_File.read(data)) != -1) {
total += count;
publishProgress((int) (total * 100 / fileLength));
out.write(data, 0, count);
}
You can add a check to see if the task is cancelled,
while ((count = input_File.read(data)) != -1 && !isCancelled()) {
total += count;
publishProgress((int) (total * 100 / fileLength));
out.write(data, 0, count);
}
and cancel the download by calling
yourAsyncTask.cancel()

You can cancel asynctask forcefully
Check This
declare your asyncTask in your activity:
private YourAsyncTask mTask;
instantiate it like this:
mTask = new YourAsyncTask().execute();
kill/cancel it like this:
mTask.cancel(true);

You can try using the below code to download the files from the url and save into the sdcard:
public void DownloadFromUrl(String DownloadUrl, String fileName) {
try {
File root = android.os.Environment.getExternalStorageDirectory();
File dir = new File (root.getAbsolutePath() + "/xmls");
if(dir.exists()==false) {
dir.mkdirs();
}
URL url = new URL(DownloadUrl); //you can write here any link
File file = new File(dir, fileName);
long startTime = System.currentTimeMillis();
Log.d("DownloadManager", "download url:" + url);
/* Open a connection to that URL. */
URLConnection ucon = url.openConnection();
/*
* Define InputStreams to read from the URLConnection.
*/
InputStream is = ucon.getInputStream();
BufferedInputStream bis = new BufferedInputStream(is);
/*
* Read bytes to the Buffer until there is nothing more to read(-1).
*/
ByteArrayBuffer baf = new ByteArrayBuffer(5000);
int current = 0;
while ((current = bis.read()) != -1) {
baf.append((byte) current);
}
/* Convert the Bytes read to a String. */
FileOutputStream fos = new FileOutputStream(file);
fos.write(baf.toByteArray());
fos.flush();
fos.close();
Log.d("DownloadManager", "download ready in" + ((System.currentTimeMillis() - startTime) / 1000) + " sec");
} catch (IOException e) {
Log.d("DownloadManager", "Error: " + e);
}
}
Also keep in mind that you specify the below permissions in your manifest file.
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"></uses-permission>
<uses-permission android:name="android.permission.INTERNET"></uses-permission>
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"></uses-permission>
<uses-permission android:name="android.permission.READ_PHONE_STATE"></uses-permission>
I hope it will help you.

How to Use Android SeekBar For File Upload and Download using FTP?

I have an issue when I am trying to download a file from server using FTP. I need to display seek-bar status of downloading file and download speed of the Internet. I am able to display seek-bar status and speed of the Internet for HTTP, but for FTP I am not able to perform that same task. In the attached image below I need to display seek-bar and network speed for FTP and HTTP. Below is the source code I used for HTTP and FTP. I don't know where I missed it?
HTTP Code:

bar = (ProgressBar) map.get("bar");
// trans = (TextView) map.get("trans");

Android Fileupload using FTP Protocal Not showing ProgressBar

In my android project i need to display seekbar and network speed(With how much speed the file is Uploading/Downloading from server using FTP Protocol). In my situation when i try to upload a file from emulator sdcard then it's showing the speed and seekbar at the end when the file is stored in the server, but my requirement is i need to show sheekbar and network speed continuously while the file is uploading into server. I am not understand where i did wrong in my code. Below is my code for file upload into ftp server:
Thanks In Advance.

Since you're calling doInBackground(), I assume you're subclassing AsyncTask. If so, why aren't you using publishProgress and onProgressUpdate? runOnUiThread doesn't execute immediately unless you're already on the UI Thread, and because you're in doInBackground() you're in a background thread, not the UI Thread. There's a possibility that runOnUiThread() isn't actually running until doInBackground() is over. In comparison, publishProgress and onProgressUpdate are specifically designed to report progress from the background thread.

force close, download file with asynctask

i have a running download function. but when i run it, like 80% of the time it make my phone laggy, force close, not responding for a very long time like 1~2 minutes. this case happened very randomly, i cant really trace what is the problem. the device will turn back to normally after the download is complete. i have tried on various devices such as galaxy S2, galaxy note, SE xperia Arc S, and few tables. problem remains the same. can anyone advice me how to improve my code? below is my existing code:
public void onClickDownload(View view){
String url = "http://www.mydomain.com./" + fileURL;
url = url.replaceAll(" ","%20");
String sourceUrl = url;
new DownloadFileAsync().execute(sourceUrl);
}
public class DownloadFileAsync extends AsyncTask<String, Integer, Void> {
private boolean run_do_in_background = true;
#Override
protected void onPreExecute(){
super.onPreExecute();
}
#Override
protected Void doInBackground(String... aurl) {
int count;
try {
URL url = new URL(aurl[0]);
URLConnection conexion = url.openConnection();
conexion.connect();
int lengthOfFile = conexion.getContentLength();
Log.d("ANDRO_ASYNC", "Lenght of file: " + lengthOfFile);
File folder = new File(Environment.getExternalStorageDirectory() + "/MaxApps");
boolean success = false;
if (!folder.exists()) {
success = folder.mkdirs();
}
if (!success) {
} else {
}
InputStream input = new BufferedInputStream(url.openStream());
OutputStream output = new FileOutputStream("/sdcard/MaxApps/" + apkURL);
byte data[] = new byte[100*1024];
long total = 0;
while ((count = input.read(data)) != -1) {
total += count;
int progressPercent = (int) ((total*100)/lengthOfFile);
if(progressPercent % 5 == 0){
publishProgress(progressPercent);
}
output.write(data, 0, count);
}
output.flush();
output.close();
input.close();
} catch (Exception e) {
notificationManager.cancel(Integer.parseInt(ID.toString()));
Notification MyN = new Notification(); MyN.icon = R.drawable.logo1;
MyN.tickerText = "Download Failed";
MyN.number = 1;
MyN.setLatestEventInfo (getApplicationContext(), apkURL + " Download Failed.", "Please try again", MyPI);
MyN.flags |= Notification.FLAG_AUTO_CANCEL;
MyNM.notify(1, MyN);
run_do_in_background = false;
}
return null;
}
#Override
protected void onProgressUpdate(Integer... progress) {
notification.contentView.setProgressBar(R.id.pbStatus, 100, progress[0], false);
notificationManager.notify(Integer.parseInt(ID.toString()), notification);
}
#Override
protected void onPostExecute(Void unused) {
if(run_do_in_background) {
notificationManager.cancel(Integer.parseInt(ID.toString()));
Notification MyN = new Notification(); MyN.icon = R.drawable.logo1;
MyN.tickerText = "Download Complete";
MyN.number = 1;
MyN.setLatestEventInfo (getApplicationContext(), "Download Complete, Click to install.", apkURL, MyPI);
MyN.flags |= Notification.FLAG_AUTO_CANCEL;
MyNM.notify(Integer.parseInt(ID.toString()) , MyN);
}
}
}

It might be that updating UI is taking long? Maybe you can try to test like this and see if it makes a difference:
#Override
protected void onProgressUpdate(Integer... progress) {
Log.d("ANDRO_ASYNC", "Progress: " + progress[0]);
}
By the way, this is not related to what you are asking, but I think you have problem in your code that handles the progress:
int progressPercent = (int) ((total*100)/lengthOfFile);
if(progressPercent % 5 == 0){
publishProgress(progressPercent);
}
That will update the progress only when it is exactly 5,10,15,20% etc... I guess you actually want to update progress when it is at least %5 further than before.
int previousProgress = 0;
while ((count = input.read(data)) != -1) {
total += count;
int progressPercent = (int) ((total*100)/lengthOfFile);
if(progressPercent - previousProgress >= 5) {
previousProgress = progressPercent;
publishProgress(progressPercent);
}
output.write(data, 0, count);
}
