Android客户端后台发送邮件（JMail)

今天在做项目的时候要处理用户注册问题，里面有个邮箱验证，网上找了一下果然有人做过，但是我拿过来都运行不起来，或者是发送不了邮件。后来我对这个浅浅的研究了一下，贴出来和大家共享。

Activity

package e.m;

import android.app.Activity;

import android.os.Bundle;

import android.util.Log;

import android.view.View;

import android.widget.Button;

public class MailSenderActivity extends Activity {

	/** Called when the activity is first created. */

	@Override

	public void onCreate(Bundle savedInstanceState) {

		super.onCreate(savedInstanceState);

		setContentView(R.layout.main);

		final Button send = (Button) this.findViewById(R.id.send);

		send.setOnClickListener(new View.OnClickListener() {

			public void onClick(View v) {

				// TODO Auto-generated method stub

				try {

					GMailSender sender = new GMailSender("lixq@gmail.com",

							"xxxxxx");

					sender.sendMail("This is Subject", "This is Body",

							"lixq@gmail.com", "lxqxxxxxu@163.com");

				} catch (Exception e) {

					Log.e("SendMail", e.getMessage(), e);

				}

			}

		});

	}

}

package e.m;

        else

           message.setRecipient(Message.RecipientType.TO, new InternetAddress(recipients));

        Transport.send(message);

        }catch(Exception e){

     }

}

   public class ByteArrayDataSource implements DataSource {

       private byte[] data;

        private String type;

        public ByteArrayDataSource(byte[] data, String type) {

           this.type = type;

        }

        public String getContentType() {

            if (type == null)

                return "application/octet-stream";

            else

               return type;

       }

            throw new IOException("Not Supported");

        }

    }

}

package e.m;

import java.security.AccessController;

import java.security.Provider;

public final class JSSEProvider extends Provider {

      public JSSEProvider() {

         super("HarmonyJSSE", 1.0, "Harmony JSSE Provider");

         AccessController.doPrivileged(new java.security.PrivilegedAction<Void>() {

             public Void run() {

                put("SSLContext.TLS",

                         "org.apache.harmony.xnet.provider.jsse.SSLContextImpl");

                 put("Alg.Alias.SSLContext.TLSv1", "TLS");

                 put("KeyManagerFactory.X509",

                         "org.apache.harmony.xnet.provider.jsse.KeyManagerFactoryImpl");

                 put("TrustManagerFactory.X509",

                         "org.apache.harmony.xnet.provider.jsse.TrustManagerFactoryImpl");

                 return null;

             }

        });

     }

 }

如果是4.0以上请将以下代码放到线程中运行。

try {

					GMailSender sender = new GMailSender("lixq@gmail.com",

							"xxxxxx");

					sender.sendMail("This is Subject", "This is Body",

							"lixq@gmail.com", "lxqxxxxxu@163.com");

				} catch (Exception e) {

					Log.e("SendMail", e.getMessage(), e);

				}

注意：这里我用的是google邮箱，如果要换其他邮箱，要在代码中设置相应的服务器。
