I got a solution. If the server supports downloading use the following code.
private final int TIMEOUT_CONNECTION = 5000; //5sec
private final int TIMEOUT_SOCKET = 30000; //30sec
private final int BUFFER_SIZE = 1024 * 5; // 5MB
try {
URL url = new URL("http://....");
//Open a connection to that URL.
URLConnection ucon = url.openConnection();
ucon.setReadTimeout(TIMEOUT_CONNECTION);
ucon.setConnectTimeout(TIMEOUT_SOCKET);
// Define InputStreams to read from the URLConnection.
// uses 5KB download buffer
InputStream is = ucon.getInputStream();
BufferedInputStream in = new BufferedInputStream(is, BUFFER_SIZE);
FileOutputStream out = new FileOutputStream(file);
byte[] buff = new byte[BUFFER_SIZE];
int len = 0;
while ((len = in.read(buff)) != -1)
{
out.write(buff,0,len);
}
} catch (IOException ioe) {
// Handle the error
} finally {
if(in != null) {
try {
in.close();
} catch (Exception e) {
// Nothing you can do
}
}
if(out != null) {
try {
out.flush();
out.close();
} catch (Exception e) {
// Nothing you can do
}
}
}
it will help.thanks
Execute all in doInBackground like this:
public class MyAsnyc extends AsyncTask<Void, Void,Void>{
public File file ;
InputStream is;
@Override
protected Void doInBackground(Void... params) {
// TODO Auto-generated method stub
try{
File path = Environment.getExternalStoragePublicDirectory(
Environment.DIRECTORY_PICTURES);
file = new File(path, "DemoPicture.jpg");
// Make sure the Pictures directory exists.
path.mkdirs();
URL url = new URL(BASE_URL);
/* Open a connection to that URL. */
URLConnection ucon = url.openConnection();
/*
* Define InputStreams to read from the URLConnection.
*/
is = ucon.getInputStream();
OutputStream os = new FileOutputStream(file);
byte[] data = new byte[is.available()];
is.read(data);
Log.d("MY_TAG>>>", "Picture is Readable...");
os.write(data);
Log.d("MY_TAG>>>", "Picture is Saved...");
is.close();
os.close();
}
catch (IOException e) {
Log.d("ImageManager", "Error: " + e);
}
return null;
}
protected void onPostExecute()
{
try
{
// Tell the media scanner about the new file so that it is
// immediately available to the user.
MediaScannerConnection.scanFile(null,
new String[] { file.toString() }, null,
new MediaScannerConnection.OnScanCompletedListener() {
public void onScanCompleted(String path, Uri uri) {
Log.i("ExternalStorage", "Scanned " + path + ":");
Log.i("ExternalStorage", "-> uri=" + uri);
}
});
}
catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
