Here is a strange error I face, while trying to download a file, I need to open the input stream and then write data read into the output stream...The Input Stream does not work...there is no error while debugging..but it just seems to hang there and F6 on the keyboard does not seem to work....Have to terminate the debug session...What am I doing wrong???
try{
URL url = new URL(pdfurl);
URLConnection conexion = url.openConnection();
conexion.connect();
int lenghtOfFile = conexion.getContentLength();
Log.d("k", "Lenght of file: " + lenghtOfFile);
//InputStream s=file
InputStream s=url.openStream();
InputStream input = new BufferedInputStream(s);
OutputStream output = new FileOutputStream(file);
byte data[] = new byte[1024];
long total = 0;
while ((count = input.read(data)) != -1) {
total += count;
publishProgress((int)((total*100)/lenghtOfFile));
output.write(data, 0, count);
}
output.flush();
output.close();
input.close();
}
catch (Exception e)
{
download_flag = true;
String s=e.getMessage().toString();
Log.d("k","exception occured"+s);
}
you could try an HttpGet request:
HttpGet httpGet = new HttpGet(url);
HttpClient httpclient = new DefaultHttpClient();
// Execute HTTP Get Request
HttpResponse response = httpclient.execute(httpGet);
content = response.getEntity().getContent();

i'm trying to make a andoid application using youtube.
i'd like to upload a video using URL.
with my codes, i received 200 http status code and success message, but actually it doesn't.
how can i resolve it?
URL url = new URL(urlString);
HttpURLConnection conn = (HttpURLConnection)url.openConnection();
conn.setDoInput(true);
conn.setDoOutput(true);
conn.setUseCaches(false);
conn.setRequestMethod("PUT");
conn.setRequestProperty("Authorization", String.format("Bearer %s", access_token));
conn.setRequestProperty("Content-Type", "video/*");
conn.setRequestProperty("Content-Length", ContentLength);
File file = new File(path);
FileInputStream fis = new FileInputStream(file);
DataOutputStream dos = new DataOutputStream(conn.getOutputStream());
int numberBytes = fis.available();
byte bytearray[] = new byte[numberBytes];
Log.e(" FileLength", String.valueOf(bytearray.length));
for(int i = 0; i < bytearray.length; i++)
dos.write(bytearray[i]);
dos.flush();
fis.close();
dos.close();
int responseCode = conn.getResponseCode();
if(responseCode == 200) {
Log.e("ResponseCode", String.valueOf(responseCode));

I need to pass an image in application/octet-stream format. I think it means binary image data. How can I convert my drawable to this format?
Here is the code where I'll pass this data in the place of body :
StringEntity reqEntity = new StringEntity("{body}");
You can use HttpURLConnection, something like this:
Long BUFFER_SIZE = 4096;
String method = "POST";
String filePath = "FILE_NAME"
File uploadFile = new File(filePath);
if (!(uploadFile.isFile() && uploadFile.exists())) {
println 'File Not Found !!!!'
return;
}
URL url = new URL("http://your_url_here/" + uploadFile.name);
HttpURLConnection httpConn = (HttpURLConnection) url.openConnection();
String contentType = "application/octet-stream"
httpConn.setDoOutput(true);
httpConn.setRequestMethod(method);
httpConn.setRequestProperty("Accept", "*/*");
httpConn.setRequestProperty("Content-type", contentType);
OutputStream outputStream = httpConn.getOutputStream();
FileInputStream inputStream = new FileInputStream(uploadFile);
byte[] buffer = new byte[BUFFER_SIZE];
int bytesRead = -1;
while ((bytesRead = inputStream.read(buffer)) != -1) {
outputStream.write(buffer, 0, bytesRead);
}
outputStream.close();
inputStream.close();
println "Response message : "+httpConn.getResponseMessage();
Im trying to download file from webservice.
the method is post and im sending json to service.
this is my code :
protected String doInBackground(String... f_url) {
int count;
try {
URL url = new URL(f_url[0]);
HttpURLConnection conn = (HttpURLConnection) url.openConnection();
conn.connect();
DataOutputStream printout;
conn = (HttpURLConnection) url.openConnection();
conn.setReadTimeout(10000);
conn.setConnectTimeout(15000);
conn.setRequestMethod("POST");
conn.setDoInput(true);
conn.setDoOutput(true);
conn.setRequestProperty("Content-Type", "application/json");
conn.setRequestProperty("Accept", "application/json");
conn.setRequestMethod("POST");
conn.connect();
//Create JSONObject here
JSONObject jsonParam = new JSONObject();
jsonParam.put("Id", 25);
// Send POST output.
printout = new DataOutputStream(conn.getOutputStream ());
printout.writeUTF(URLEncoder.encode(jsonParam.toString(),"UTF-8"));
printout.flush ();
printout.close ();
int status = conn.getResponseCode();
// getting file length
int lenghtOfFile = conn.getContentLength();
Log.d("lenghtOfFile : ", lenghtOfFile + "byte");
// input stream to read file - with 8k buffer
InputStream input = new BufferedInputStream(url.openStream());
// Output stream to write file
OutputStream output = new FileOutputStream("backup.db");
byte data[] = new byte[1024];
long total = 0;
while ((count = input.read(data)) != -1) {
total += count;
// publishing the progress....
// After this onProgressUpdate will be called
publishProgress(""+(int)((total*100)/lenghtOfFile));
// writing data to file
output.write(data, 0, count);
}
// flushing output
output.flush();
// closing streams
output.close();
input.close();
} catch (Exception e) {
Log.e("Error: ", e.toString());
}
return null;
}
status code is 200 and the size of lenghtOfFile is the file im trying to
download , but at this line :
InputStream input = new BufferedInputStream(url.openStream());
program gives error :
05-28 09:11:25.513: E/Error:(627): java.io.FileNotFoundException: http://example.com/api/Values
i even changed the buffer size to content size but still no hope.
I'm trying to download a file in my app, but the download times are inconsistently too long.
Sometimes it just downloading it in normal time, but sometimes it just stuck for like 30 seconds or more until it will just fail due to time out error.
Why would that be?
private void Download(String url, String destFileName) throws IOException{
//TODO remove that
// File file = new File(destFileName);
// if(file.exists())
// return;
if(BuildConfig.DEBUG)
Log.d("DownloadFile", "Downloading url: " + url + ", dest: " + destFileName);
HttpGet httppost = null;
AndroidHttpClient client = AndroidHttpClient.newInstance("TvinciAndroid");
FileOutputStream fos = new FileOutputStream(destFileName);
try {
httppost = new HttpGet(url);
HttpResponse res = client.execute(httppost);
if (res.getStatusLine().getStatusCode() != HttpStatus.SC_OK) {
Header[] headers = res.getHeaders("Location");
if(headers != null && headers.length != 0) {
url = headers[headers.length - 1].getValue();
Download(url, destFileName);
}
}
HttpEntity responseEntity = res.getEntity();
if (responseEntity != null && responseEntity.getContentLength() > 0) {
InputStream is = AndroidHttpClient.getUngzippedContent(responseEntity);
BufferedReader reader = new BufferedReader(new InputStreamReader(is,Charset.forName("UTF-8")));
StringBuilder bld = new StringBuilder();
String line;
while ((line = reader.readLine()) != null) {
line += "\n";
fos.write(line.getBytes());
bld.append(line);
}
reader.close();
if(BuildConfig.DEBUG)
Log.d("file content", bld.toString());
bld = null;
}
}
catch(IOException ex){
throw ex;
}
finally {
client.close();
fos.close();
}
}
Any help will be much appreciated
Try specifying the buffer to 8192.
//input stream to read file - with 8k buffer
InputStream input = new BufferedInputStream(url.openStream(), 8192);
I have a sample working code here that can download a file via URL It is different from your implementation, but this might help you.
try {
URL url = new URL(f_url[0]);
URLConnection conection = url.openConnection();
// getting file length
int lengthOfFile = conection.getContentLength();
// input stream to read file - with 8k buffer
InputStream input = new BufferedInputStream(url.openStream(), 8192);
// Output stream to write file
OutputStream output = new FileOutputStream(filePath);
byte data[] = new byte[1024];
long total = 0;
pDialog.setMax(lengthOfFile);
NOTIFICATION_ID = 1+lengthOfFile;
while ((count = input.read(data)) != -1) {
total += count;
// publishing the progress....
// After this onProgressUpdate will be called
//publishProgress(""+(int)((total*100)/lenghtOfFile));
publishProgress(""+(int)(total));
notifBuilder.setProgress(lengthOfFile, (int)(total), false)
.setContentText("Download in progress... "+total+"/"+lengthOfFile);
nm.notify(NOTIFICATION_ID, notifBuilder.build());
// writing data to file
output.write(data, 0, count);
}
// flushing output
output.flush();
// closing streams
output.close();
input.close();
} catch (IOException e) {
e.printStackTrace();
Log.e("Error: ", e.getMessage());
return e.getMessage()+" download failed!";
}
I Hope this helps.
In my app, I have requirement to download mp3 files from url. I am downloading file using Async Task. For testing purpose, I have kept file in dropbox. The problem is, it is not downloading complete file. The actual file size is of 5 MB. But, it is downloading only 29 KB of data. When I checked the length of content, it showed -1. I am not getting where is the problem. Below, I am posting my code.
#Override
protected Void doInBackground(String... sUrl)
{
InputStream input = null;
OutputStream output = null;
try
{
URL link = new URL(sUrl[0]);
HttpURLConnection urlConnection = (HttpURLConnection)link.openConnection();
urlConnection.setRequestMethod("GET");
urlConnection.setDoOutput(true);
urlConnection.connect();
int fileLength = urlConnection.getContentLength();
Log.v("Download file length", ""+fileLength);
input = urlConnection.getInputStream();
int downloadedSize = 0;
output = new FileOutputStream(Environment.getExternalStorageDirectory()
.getAbsolutePath()+"/audiofolder/1.mp3.mp3");
byte[] data = new byte[1024];
int bufferLength = 0;
while (((bufferLength = input.read(data)) > 0))
{
output.write(data, 0, bufferLength);
downloadedSize += bufferLength;
publishProgress((int)((downloadedSize/fileLength) * 100));
}//while
output.flush();
output.close();
input.close();
}//try
catch (MalformedURLException e)
{
e.printStackTrace();
}//catch
catch (IOException e)
{
e.printStackTrace();
}//catch
return null;
}//diInBackground
in My Application the Below Code Works Perfectly. you can try this Out.
#Override
protected Void doInBackground(String... aurl) {
try {
URL url = new URL(aurl[0]);
URLConnection conexion = url.openConnection();
conexion.connect();
File file = new File("mnt/sdcard/");
file.mkdirs();
File outputfile = new File(file, title + ".mp3");
FileOutputStream fileOutput = new FileOutputStream(outputfile);
InputStream inputStream = conexion.getInputStream();
int totalSize = conexion.getContentLength();
int downloadedSize = 0;
byte[] buffer = new byte[1024];
int bufferLength = 0;
while ((bufferLength = inputStream.read(buffer)) != -1) {
downloadedSize += bufferLength;
onProgressUpdate((int) ((downloadedSize * 100) / totalSize));
fileOutput.write(buffer, 0, bufferLength);
}
fileOutput.close();
} catch (Exception e) {
download = true;
e.printStackTrace();
}
return null;
}
Check your link.
When you see length of content = -1, it mean there is no length of content in header of link. It don't force under your download progress.
You only download 29KB because it download website, .html not file mp3.
Yout can copy and paste your link on brower to check.
From Android Documentation:
https://developer.android.com/reference/java/net/URLConnection.html#getContentLength()
getContentLength returns:
the content length of the resource that this connection's URL references, -1 if the content length is not known, or if the content length is greater than Integer.MAX_VALUE.
