and in the file manager I look at
it is broken
Can you help?

Instead of using AsyncTask to download images from URL. You can use libraries such as Glide or Picasso to do it quickly just in one line. But if you don't want to use libraries than you could use DownloadManager to download it and save it in a file. You can check this tutorial or other tutorials on the web for the implementation of DownloadManager.
I want to download zip file from server by using ksoap liabry.I am getting data in base64 please give solution that how to convert base64 and save it as zip file
byte[] bytes;
byte[] data = result.getBytes("UTF-8");
File outputFile = new File(mediaStorageDir.getAbsolutePath(), + "filename.zip");
new FileOutputStream(outputFile);
bytes = Base64.decode(data, Base64.DEFAULT);
File filepath = new File(Environment.getExternalStorageDirectory(), "Folder/" + "filename.zip");
OutputStream pdffos = new FileOutputStream(filepath);
pdffos.write(bytes);
pdffos.flush();
pdffos.close();

How can I solve this problem?
According to documentation of getContentLength:
Returns the content length in bytes specified by the response header
field content-length or -1 if this field is not set or cannot be
represented as an int.
If you will check your link here, then you will spot, that Content Length was not set.
(I will just add, that I was not checking fully your code, but generally in main downloading loop with buffer - is downloading something, but I was not checking if it was correct, or not)
EDIT: I'm gonna 'hate' guy, that gave me '-1'. I'm helping with detail link and how checking it, why content length is returning -1, and someone is giving me negative. I change little downloadFile function just to download file, without giving update to UI, and then we have:
void downloadFile(){
try {
URL url = new URL(dwnload_file_path);
HttpURLConnection urlConnection = (HttpURLConnection) url.openConnection();
urlConnection.setRequestProperty("Accept-Encoding", "gzip");
urlConnection.setRequestMethod("GET");
urlConnection.setDoOutput(true);
//connect
urlConnection.connect();
//set the path where we want to save the file
//create a new file, to save the downloaded file
File file = new File("downloaded_file.png");
FileOutputStream fileOutput = new FileOutputStream(file);
//Stream used for reading the data from the internet
InputStream inputStream = urlConnection.getInputStream();
System.out.println("ENCODING"+urlConnection.getContentEncoding());
if ("gzip".equals(urlConnection.getContentEncoding())) {
inputStream = new GZIPInputStream(inputStream);
}
InputSource is = new InputSource(inputStream);
//this is the total size of the file which we are downloading
totalSize = urlConnection.getContentLength();
//create a buffer...
byte[] buffer = new byte[1024];
int bufferLength = 0;
while ( (bufferLength = inputStream.read(buffer)) > 0 ) {
fileOutput.write(buffer, 0, bufferLength);
downloadedSize += bufferLength;
// update the progressbar //
}
//close the output stream when complete //
fileOutput.close();
} catch (final MalformedURLException e) {
e.printStackTrace();
} catch (final IOException e) {
e.printStackTrace();
}
catch (final Exception e) {
e.printStackTrace();
}
}
As I checked this code is downloading file, but it isn't this image, but html page from zippyshare, as zippy has kind of protection to download files from their site.
