i found the problem by myself. It's problem of the usage of deflater,
correct solution should be:
public static byte[] deflaterCompress(String str) throws IOException
{
TOTAL_LEN = 0;
byte[] input = str.getBytes(encoding);
Deflater deflater = new Deflater();
deflater.setInput(input);
deflater.finish();
 byte[] buf = new byte[8192];
 ByteArrayOutputStream baos = new ByteArrayOutputStream();
 while (!deflater.finished()) {
 int byteCount = deflater.deflate(buf);
 TOTAL_LEN += byteCount;
 baos.write(buf, 0, byteCount);
 }
 deflater.end();

 byte[] compressedBytes = baos.toByteArray();
 return compressedBytes;
}

Have you add the internet permission in manifest like this?
android:name="android.permission.INTERNET">

I use deflater to compress string data. It works fine on java console 
project, but while running on android enviroment, server will report 
"buffer error" problem and reture 500.


SendMessage(String content, String url)
{
byte[] bs = deflaterCompress(content);
URL url = new URL(urlStr);
   HttpURLConnection httpConn = (HttpURLConnection) 
url.openConnection();

   httpConn.setDoOutput(true);
   httpConn.setRequestMethod("POST");
   httpConn.setDoInput(true);
   //httpConn.setRequestProperty("Content-length", 
String.valueOf(UmengDeviceHelper.TOTAL_LEN));
   httpConn.setRequestProperty("Content-Type", 
"application/octet-stream");

   httpConn.setRequestProperty("Content-Encoding", "deflate");
   httpConn.connect();
   DataOutputStream outputStream = new 
DataOutputStream(httpConn.getOutputStream());

   outputStream.write(bs);
   //outputStream.write(content.getBytes("utf-8"));
   outputStream.flush();
   outputStream.close();
   int responseCode = 500;
   try {
   responseCode = httpConn.getResponseCode();
   Log.i("MobclickAgent", "reture code is:" + responseCode);
   } catch (NumberFormatException e) {
   // ignore
e.printStackTrace();
   }
}

public static byte[] deflaterCompress(String str) throws IOException
{
byte[] input = str.getBytes(encoding);
byte[] output = new byte[100];
Deflater compresser = new Deflater();
compresser.setInput(input);
compresser.finish();
TOTAL_LEN = compresser.deflate(output);
return output;

You do not set content length. It supposes to be chunked, but it's worth to 
set some http watcher and see what actually you transfer.

I use deflater to compress string data. It works fine on java console
project, but while running on android enviroment, server will report "buffer
error" problem and reture 500.

SendMessage(String content, String url)
{
byte[] bs = deflaterCompress(content);
 URL url = new URL(urlStr);
HttpURLConnection httpConn = (HttpURLConnection)
url.openConnection();
httpConn.setDoOutput(true);
httpConn.setRequestMethod("POST");
httpConn.setDoInput(true);

//httpConn.setRequestProperty("Content-length",
String.valueOf(UmengDeviceHelper.TOTAL_LEN));
httpConn.setRequestProperty("Content-Type",
"application/octet-stream");
httpConn.setRequestProperty("Content-Encoding", "deflate");
httpConn.connect();
DataOutputStream outputStream = new
DataOutputStream(httpConn.getOutputStream());
outputStream.write(bs);
//outputStream.write(content.getBytes("utf-8"));
outputStream.flush();
outputStream.close();

int responseCode = 500;
try {
responseCode = httpConn.getResponseCode();
Log.i("MobclickAgent", "reture code is:" + responseCode);
} catch (NumberFormatException e) {
// ignore
 e.printStackTrace();
}
}

public static byte[] deflaterCompress(String str) throws IOException
{
byte[] input = str.getBytes(encoding);
byte[] output = new byte[100];
Deflater compresser = new Deflater();
compresser.setInput(input);
compresser.finish();
TOTAL_LEN = compresser.deflate(output);
 return output;
}
