使用AsyncTask发送Android电子邮件 [英] Using AsyncTask to Send Android Email

问题描述

我最近问过关于以下代码的问题：

使用JavaMail API在Android中发送电子邮件，而不使用默认/内置应用

根据以前的问题，我已经询问过网络错误：

需要帮助调试电子邮件代码

我的问题是，怎么我实现一个AsyncTask，以便成功发送一个这个Android代码的电子邮件？我看到的每个教程都告诉我，我应该做

  extends AsyncTask {
  / pre> 
 
 
但是，GMailSender.java已经定义为：
  public class GMailSender extends javax.mail.Authenticator 
  
有人能帮助我吗？谢谢！
 
 
 
注意：
 
 
 
请不要像笨蛋一样有-1  ed 这个问题，并发布了确切的答案，如使用JavaMail API在Android中发送电子邮件，而不使用默认/内置应用。由于不可能在Android应用程序的主线程上运行网络操作，因此无法使用精确的编码。我正在寻找一种使用AsyncTask的方法，以便在后台运行该操作。我无法找出是如何做的
 扩展AsyncTask {
  / pre> 
 
 
不触摸
  public class GMailSender extends javax.mail .Authenticator 
  
 
 
解决方案
有一个很好的例子  AsyncTask  doc页面。 
 
 
 
将您的 GMailSender 对象传递给 AsyncTask 并在 doInBackground 中调用 GMailSender＃sendMail 。
 
 
 
是，
  public void onClick（View v）{
 final GMailSender sender = new GMailSender（username @ gmail。 com，密码）; 
 new AsyncTask< Void，Void，Void>（）{
 @Override public Void doInBackground（Void ... arg）{
 try {
 sender.sendMail（This is主题，
This is Body，
[e-mail]，
[e-mail]）; 
} catch（Exception e）{
 Log.e（SendMail，e.getMessage（），e）; 
} 
} 
} .execute（）; 
 
} 
  
 
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 -1ed 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();

}
