I am developing an android application in which i have to post some data to url.I did googling and got some samples.I tried them out.But i did not got the response as required.
Below is the link which i tried
http://www.androidsnippets.com/executing-a-http-post-request-with-httpclient
Has anyone done this before.If yes can he help me
Thanks in advance

I create a class with all my information I need to send and serialize it to a xml file with simple xml. Then I send the entire XML.
But you can send fields only too:
static String CRLF = "\r\n";
static String twoHyphens = "--";
static String boundary = "*****mgd*****";
private DataOutputStream dataStream = null;
private void postData(){
try{

HttpURLConnection conn = (HttpURLConnection)connectURL.openConnection();
conn.setDoInput(true);
conn.setDoOutput(true);
conn.setUseCaches(false);
conn.setRequestMethod("POST");
conn.setRequestProperty("User-Agent", "test");
conn.setRequestProperty("Connection","Keep-Alive");
conn.setRequestProperty("Content-Type","multipart/form-data;boundary="+boundary);
conn.connect();
dataStream = new DataOutputStream(conn.getOutputStream());
//Send fields
writeFormField("name", "bla");
writeFormField("password", "bla");
//Send a file
File uploadFile = new File(SD_CARD_TEMP_DIR, "file.xml");
FileInputStream fileInputStream = new FileInputStream(uploadFile);
writeFileField("myFile", "somefilename.xml", "text/xml",fileInputStream);
// final closing boundary line
dataStream.writeBytes(twoHyphens + boundary +twoHyphens + CRLF);
fileInputStream.close();
dataStream.flush();
dataStream.close();
dataStream = null;

Your question is still pretty vague, but one of the reasons this happens is- when you're fetching the relative URI of the File, but need the Absolute URI for the upload.
You can check out different FileUtil classes like this https://github.com/z0rawarr/AndroidUtilCode/blob/master/utilcode/src/main/java/com/blankj/utilcode/utils/FileUtils.java
Get the absolute path from the URI and use that to upload.
Also, do not forget to use the Debugger, and apply a breakpoint on uploadFile() to debug the URIs.
I'm trying to upload a video from my android phone (Samsung Galaxy s2) with version 4.1.2.
I have configured an apache server which hosts the uploaded video. My problem is the following : everytime I upload a video from my phone, I have a corrupted file. The file on the server has a few bytes less than the phone's file. It does not come from the server as I've made some tests using an html form and everything went well. So I guess, it's coming from my code but I just can't figure where. Can somebody help me please, I've spent days on it.
This is my code :

It works fine but,the file contains 20 lines it saved in the sever with 22 lines.
My actual file looks like as follows.
android app info
app name
app time
when i will send the flle to server from sd card the file look like as follows
1)**mnt/sdcard/111**
android app info
app name
app time
2)**
1 and 2 lines are added.
How i can send a file without those two lines .
If any one know the solution please help me .
Thanks in advance..

While smaller than 16 mb, it upload success.
But while it more than 16 mb, the "OutOfMemory" error show.
How to avoid the outofmemory error?
Did you try using
con.setChunkedStreamingMode(1024);
This will help you to chunk your data into specific size, so that you need not keep your entire file in the memory.
UPDATE:
Try using the below method. I use this method to upload a 80 mb file without Exception.

if Server accept chunked mode, you can use
((HttpURLConnection) con).setChunkedStreamingMode(chunkLength)
otherwise you can use
((HttpURLConnection) con).setChunkedStreamingMode(0);
or
/* compute first your request content length
contentLength = formBodyLength + yourFileSize
*/
con.setRequestProperty("Content-Length", String.valueOf(contentLength));
((HttpURLConnection) con).setFixedLengthStreamingMode(contentLength);
finally... send what you want
bitmap=Bitmap.createScaledBitmap(bitmap, 100, 100, true);
ByteArrayOutputStream stream = new ByteArrayOutputStream();
bitmap.compress(Bitmap.CompressFormat.PNG, 100, stream); //compress to format you want.
byte [] byte_arr = stream.toByteArray();
String image_str = Base64.encodeBytes(byte_arr);
Best Way I tried it was successful for me!!!
I want to copy all the video files on my server & save it in the web contents folder of a web service , so that it can be visible to all later on !
How should i proceeed ?
Basically you need two sides. The first one is on Android. You have to send (Do it in an ASyncTask e.x.) the data to your webservice. Here I made a little method for you, which sends a file and some additional POST values to an URL:

// Some POST values
outStream.writeBytes(addParam("additional_param", "some value");
outStream.writeBytes(addParam("additional_param 2", "some other value");
// The file with the name "uploadedfile"
outStream.writeBytes(twoHyphens + boundary + lineEnd);
outStream.writeBytes("Content-Disposition: form-data; name=\"uploadedfile\";filename=\"" + filePath +"\"" + lineEnd + "Content-Type: " + mimeType + lineEnd + "Content-Transfer-Encoding: binary" + lineEnd);

inStream.close();
} catch (IOException e){
Log.e("APP", "IOException while sending\n" + e.getMessage());
}
return false;
}
Now, we have got the other side: http://your.domain.com/webservice.php
Your server. It needs some logic, for example in PHP, to handle the sent POST request.
Something like this would work:
<?php
$target_path = "videos/";
$target_path = $target_path.'somename.3gp';
if(move_uploaded_file($_FILES['uploadedfile']['tmp_name'], $target_path)) {
exit("UPLOAD OK");
} else {
exit("UPLOAD NOT OK");
}
?>
