Upload Files to a Web Server - Simplest TLS Example

See more Upload Examples

This is the simplest example for uploading some files to a web server using SSL/TLS. the BlockingUpload call is synchronous and returns when the upload is finished (or failed).

A server-side C# example showing how to receive an upload is located at C# ASP.NET Code to Receive Upload

// Important: Don't forget to include the call to System.loadLibrary
// as shown at the bottom of this code sample.
package com.test;

import android.app.Activity;
import com.chilkatsoft.*;

import android.widget.TextView;
import android.os.Bundle;

public class SimpleActivity extends Activity {

  private static final String TAG = "Chilkat";

  // Called when the activity is first created.
  @Override
  public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    boolean success = false;

    CkUpload upload = new CkUpload();

    // Specify the page (ASP, ASP.NET, Perl, Python, Ruby, CGI, etc)
    // that will receive and process the HTTPS Upload.
    upload.put_Hostname("www.mywebserver.com");
    upload.put_Path("/receiveUpload.aspx");

    // Make sure to indicate that TLS is to be used, and the port should be
    // 443 rather than 80.
    upload.put_Ssl(true);
    upload.put_Port(443);

    // Add one or more files to be uploaded.
    upload.AddFileReference("file1","dude.gif");
    upload.AddFileReference("file2","swordfish.xml");
    upload.AddFileReference("file3","sample.doc");

    // Do the upload.  The method returns when the upload
    // is completed.
    // This component also includes asynchronous upload capability,
    // which is demonstrated in another example.
    success = upload.BlockingUpload();
    if (success != true) {
        Log.i(TAG, upload.lastErrorText());
        }
    else {
        Log.i(TAG, "Files uploaded!");
        }


  }

  static {
      System.loadLibrary("chilkat");

      // Note: If the incorrect library name is passed to System.loadLibrary,
      // then you will see the following error message at application startup:
      //"The application <your-application-name> has stopped unexpectedly. Please try again."
