问题描述

我最近问关于以下code的一个问题：

<一个href="http://stackoverflow.com/questions/2020088/sending-email-in-android-using-javamail-api-without-using-the-default-built-in-a">Sending电子邮件在Android中使用JavaMail API不使用默认/内置应用

我在关于网络错误问这个，因为每一个previous问题：

需要帮助调试电子邮件code

我的问题是，我怎么会为了成功地发送邮件与这个Android code实现一个AsyncTask的？每一个教程，我看到告诉我，我应该怎么办

 扩展AsyncTask的{
 

不过，GMailSender.java已经有此定义为：

 公共类GMailSender扩展javax.mail.Authenticator
 

会有人能帮助我吗？谢谢！

请注意：

请不要喜欢谁了-1 ^版这个问题，并公布了确切的答案在<一个被赋予了白痴href="http://stackoverflow.com/questions/2020088/sending-email-in-android-using-javamail-api-without-using-the-default-built-in-a">Sending电子邮件在Android中使用JavaMail API不使用默认/内置应用。我无法使用了精确的编码，由于这样的事实，它是不再可能一个Android应用程序的主线程上运行的网络操作。我正在寻找一种方式来使用的AsyncTask，以便在后台运行操作。什么我无法找出是怎么做的。

解决方案

有一个pretty的很好的例子，对上的 的AsyncTask 文档页面。

通过你的 GMailSender 对象中的的AsyncTask ，并调用 GMailSender＃sendmail的在 doInBackground 。

也就是说，

 公共无效的onClick（视图v）{
    最后GMailSender发件人=新GMailSender（[e-mail]，密码）;
    新的AsyncTask＆LT;虚空，虚空，虚空＆GT;（）{
        @覆盖公共无效doInBackground（空... ARG）{
            尝试 {
                sender.sendMail（这是主题
                    这是身体，
                    [e-mail]
                    [e-mail]）;
            }赶上（例外五）{
                Log.e（Sendmail的，e.getMessage（），E）;
            }
        }
    }。执行（）;

}
 

I had recently asked a question regarding the following code:

Sending Email in Android using JavaMail API without using the default/built-in app

I had asked this in regards to a network error, as per a previous question:

Need Help Debugging Email Code

My question is, how would I implement an AsyncTask in order to successfully send an email with this Android code? Every tutorial that I see informs me that I should do

extend AsyncTask {

However, GMailSender.java already has this defined as:

public class GMailSender extends javax.mail.Authenticator

Would anyone be able to help me? Thanks!

NOTE:

Please don't be like the idiot who had -1^ed this question and posted the exact answer as was given in Sending Email in Android using JavaMail API without using the default/built-in app. I am unable to use that exact coding, due to the fact that it is no longer possible to run a network operation on the main thread of an Android application. I am looking for a way to use AsyncTask in order to run the operation in the background. What I am unable to find out is how to do

extend AsyncTask {

without touching

public class GMailSender extends javax.mail.Authenticator

解决方案

There is a pretty good example right on the AsyncTask doc page.

Pass your GMailSender object in to an AsyncTask, and call GMailSender#sendMail during doInBackground.

That is,

public void onClick(View v) {
    final GMailSender sender = new GMailSender("[e-mail]", "password");
    new AsyncTask<Void, Void, Void>() {
        @Override public Void doInBackground(Void... arg) {
            try {   
                sender.sendMail("This is Subject",   
                    "This is Body",   
                    "[e-mail]",   
                    "[e-mail]");   
            } catch (Exception e) {   
                Log.e("SendMail", e.getMessage(), e);   
            } 
        }
    }.execute();

}
