Here is the code I use and I have never had any issue out of it.
HttpURLConnection hucConnection = null;
try
{
URL uInfo = new URL( YOUR_URL_HERE );
hucConnection = (HttpURLConnection)uInfo.openConnection();
hucConnection.setRequestMethod( "POST" );
hucConnection.setRequestProperty( "Accept-Encoding", "identity" );
hucConnection.setDoOutput( true );
String sPost = URLEncoder.encode( "key1", "UTF-8") + "=" +
URLEncoder.encode( "value1", "UTF-8");
sPost += "&" + URLEncoder.encode( "key2", "UTF-8") + "=" +
URLEncoder.encode( "value1", "UTF-8");
sPost += "&" + URLEncoder.encode( "key3", "UTF-8") + "=" +
URLEncoder.encode( "value1", "UTF-8");
OutputStreamWriter out = new OutputStreamWriter(
hucConnection.getOutputStream() );
out.write( sPost );
out.flush();
int iSize = hucConnection.getContentLength();
byte[] bReturn = new byte[ iSize ];
InputStream in = new BufferedInputStream( hucConnection.getInputStream() );
in.read( bReturn, 0, iSize );
String sReturn = new String( bReturn );
Log.i( "URL Return", "Return: " + sReturn );
}
catch( Exception e ) { e.printStackTrace(); }
finally { hucConnection.disconnect(); }
I use the accept-encoding line to disable compression because I don't send
large amounts of data via the connection and it simply (and speeds up)
processing the return. See the note in the following link for more
information.
Depending on what platform version you are aiming for, you may want to check
out the following link:

It will give you more detail about what they recommend.
