Download the large file from the server

Download the large file from the server asynchronously in android with the below code....

call this:

new DownloadFileAsync(YourActivity.this).execute();

And your DownloadFileAsync is as below:

class DownloadFileAsync extends AsyncTask<String, String, String> {

@Override
protected void onPreExecute() {
super.onPreExecute();
showDialog(DIALOG_DOWNLOAD_PROGRESS);
}

@Override
protected String doInBackground(String... aurl) {
int count;

try {

// URL url = new URL(DOWNLOAD URL);

URLConnection conexion = url.openConnection();
conexion.connect();

int lenghtOfFile = conexion.getContentLength();
Log.d("ANDRO_ASYNC", "Lenght of file: " + lenghtOfFile);

InputStream input = new BufferedInputStream(url.openStream());
File filedir = new File(path);
// have the object build the directory structure, if needed.
filedir.mkdirs();
OutputStream output = new FileOutputStream(path + name + ".zip");

byte data[] = new byte[1024];

long total = 0;

while ((count = input.read(data)) != -1) {
total += count;
publishProgress("" + (int) ((total * 100) / lenghtOfFile),
name);
output.write(data, 0, count);
}

output.flush();
output.close();
input.close();

} catch (Exception e) {
}
return null;

}

protected void onProgressUpdate(String... progress) {
Log.d("ANDRO_ASYNC", progress[0]);
mProgressDialog.setMessage("Downloading " + progress[1] + ".....");
mProgressDialog.setProgress(Integer.parseInt(progress[0]));
}

@Override
protected void onPostExecute(String unused) {
dismissDialog(DIALOG_DOWNLOAD_PROGRESS);
new UnzipFile(BookDownloadActivity.this, path + name + ".zip", path)
.execute();
}
}

@Override
protected Dialog onCreateDialog(int id) {
switch (id) {
case DIALOG_DOWNLOAD_PROGRESS:
mProgressDialog = new ProgressDialog(this);
mProgressDialog.setMessage("Downloading file.....");
mProgressDialog.setProgressStyle(ProgressDialog.STYLE_HORIZONTAL);
mProgressDialog.setCancelable(false);
mProgressDialog.show();
return mProgressDialog;
default:
return null;
}
}


This is how you can download the whole file from the server or any other URLs.
