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

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;
}
