I sent this to the group, but it may take a while for my post to get
approved.
I would try using the Apache HttpClient instead of HttpsURLConnection.
package khuber.sendlargefile;
import java.io.File;
import java.io.FileInputStream;
import java.io.InputStream;
import org.apache.http.HttpEntity;
import org.apache.http.HttpResponse;
import org.apache.http.client.HttpClient;
import org.apache.http.client.methods.HttpPost;
import org.apache.http.entity.InputStreamEntity;
import org.apache.http.impl.client.DefaultHttpClient;
import android.app.Activity;
import android.os.Bundle;
import android.os.Environment;
import android.os.Handler;
import android.util.Log;
import android.widget.TextView;
public class SendLargeFile extends Activity {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
Sender s = new Sender();
s.start();
}
final Handler handler = new Handler();
final Runnable showMessage = new Runnable() {
public void run() {
message();
}
};
String message;
public void message() {
TextView tv = new TextView(this);
tv.setText("response=" + message);
setContentView(tv);
}
class Sender extends Thread {
public void run() {
String msg = "";
String url = "http://192.168.0.128:8080/PostDemo/
PostServlet";
File file = new
File(Environment.getExternalStorageDirectory(),
"test2.dat");
try {
HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost(url);
Log.i("SendLargeFile", "before send");
Log.i("SendLargeFile", "file length = " +
file.length());
InputStreamEntity reqEntity = new InputStreamEntity(
new FileInputStream(file), -1);
reqEntity.setContentType("binary/octet-stream");
reqEntity.setChunked(true);
httppost.setEntity(reqEntity);
Log.i("SendLargeFile", "before execute");
HttpResponse response = httpclient.execute(httppost);
Log.i("SendLargeFile", "response = " +
response.getStatusLine());
HttpEntity resEntity =
response.getEntity();
StringBuilder sb = new StringBuilder();
if (resEntity != null) {
byte[] buf = new byte[512];
InputStream is = resEntity.getContent();
int n = 0;
while ((n = is.read(buf)) > 0) {
sb.append(new String(buf, 0, n));
}
is.close();
resEntity.consumeContent();
}
msg = sb.toString();
} catch (Exception e) {
msg = e.toString();
}
message = msg;
handler.post(showMessage);
}
}
}
