Android™ Java Libraries

Android C/C++ Libraries

// 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);

    // This example requires the Chilkat API to have been previously unlocked.
    // See Global Unlock Sample for sample code.

    boolean success;

    // Use the Chilkat Email API to create or load an email.
    CkEmail email = new CkEmail();

    // The From name/address don't need to be specified. 
    // GMail will automatically use your Gmail address if the following 2 lines are omitted.
    email.put_FromName("My Name");
    email.put_FromAddress("my_account_name@gmail.com");

    email.AddTo("John Smith","somebody@somewhere.com");
    // To add more recipients, make additional calls to AddTo or AddCC, one per recipient...

    // -----------------------------------------------------------------------------------------
    // This section of this example demonstrates how to add BCC recipients.
    // 
    // Technically, an email should never contain a "Bcc" MIME header because it would
    // effectively nullify the purpose of BCC -- which means "Blind Carbon Copy".
    // Email recipients should not be able to see the BCC recipients.
    // Chilkat never adds a "Bcc" header field.
    // However.. in this case, the GMail REST server will look for the Bcc header field,
    // and will include those email addresses when sending, and also removes the Bcc header
    // from the email that is sent.
    // 
    // Starting in Chilkat v9.5.0.91, we can tell the email object to add the Bcc header
    // using the "UseBccHeader" UncommonOptions.  For example:
    email.put_UncommonOptions("UseBccHeader");
    email.AddBcc("Joe","joe@example.com");
    email.AddBcc("Dave","dave@example.com");
    // ...
    // -----------------------------------------------------------------------------------------

    email.put_Subject("This is a test GMail email created using Chilkat.");
    email.put_Charset("utf-8");
    email.AddPlainTextAlternativeBody("This is a test");

    // Create an HTML email body with an embedded image.
    String cid = email.addRelatedFile("qa_data/jpg/starfish.jpg");
    CkStringBuilder sbHtml = new CkStringBuilder();
    sbHtml.Append("<html><body>This is a <b>test</b><br><img src=\"cid:STARFISH_CID\"/></body></html>");
    int numReplacements = sbHtml.Replace("STARFISH_CID",cid);

    email.AddHtmlAlternativeBody(sbHtml.getAsString());

    // OK.. we now have an HTML email with an embedded JPG image
    // We'll need to get the full MIME of the email encoded to a base64url string.
    CkStringBuilder sbMime = new CkStringBuilder();
    email.GetMimeSb(sbMime);
    sbMime.Encode("base64url","utf-8");

    // The body of the HTTP request will be JSON..
    CkJsonObject json = new CkJsonObject();
    json.UpdateSb("raw",sbMime);

    // Send the email...
    CkHttp http = new CkHttp();
    http.put_AuthToken("GMAIL-ACCESS-TOKEN");

    String url = "https://www.googleapis.com/gmail/v1/users/me/messages/send";
    CkHttpResponse resp = http.PostJson3(url,"application/json",json);
    if (http.get_LastMethodSuccess() != true) {
        Log.i(TAG, http.lastErrorText());
        return;
        }

    // A status code of 200 indicates success.
    Log.i(TAG, "Response status code: " + String.valueOf(resp.get_StatusCode()));
    Log.i(TAG, "Response body:");
    Log.i(TAG, resp.bodyStr());

    // The response body contains JSON.
    // Use the online tool at Generate JSON Parsing Code
    // to generate JSON parsing code.

    // A sample successful JSON response:

    // {
    //  "id": "166f0d4ac39e50bf",
    //  "threadId": "166f0d4ac39e50bf",
    //  "labelIds": [
    //   "SENT"
    //  ]
    // }

  }

  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."
