Question

我的代码是关于在后台发送电子邮件。我曾尝试过这些代码（来自stackoverflow），但它不起作用。

public class MainActivity extends Activity {

EditText email;

@Override
protected void onCreate(Bundle icicle) {
    super.onCreate(icicle);
    setContentView(R.layout.activity_main);
    email = (EditText) findViewById(R.id.editText1);
    Button addImage = (Button) findViewById(R.id.send_email); 

    addImage.setOnClickListener(new View.OnClickListener() { 
        public void onClick(View view) { 

            new SendEmailAsyncTask().execute();
        }

        class SendEmailAsyncTask extends AsyncTask <Void, Void, Boolean> {
            Mail m = new Mail("gmailusername@gmail.com", "password");

            public SendEmailAsyncTask() {
                if (BuildConfig.DEBUG)    
          Log.v(SendEmailAsyncTask.class.getName(), "SendEmailAsyncTask()");
                String[] toArr = { "bla@bla.com", "lala@lala.com"};
                m.setTo(toArr);
                m.setFrom("wooo@wooo.com");
                m.setSubject("Email from Android");
                m.setBody("body.");
            }

            @Override
            protected Boolean doInBackground(Void... params) {
                if (BuildConfig.DEBUG)
                  Log.v(SendEmailAsyncTask.class.getName(), "doInBackground()");
                try {
                    m.send();
                    return true;
                } catch (AuthenticationFailedException e) {
                    Log.e(SendEmailAsyncTask.class.getName(), "Bad account 
                         details");
                    e.printStackTrace();
                    return false;
                } catch (MessagingException e) {
                    Log.e(SendEmailAsyncTask.class.getName(), m.getTo(null) + 
                "failed");
                    e.printStackTrace();
                    return false;
                } catch (Exception e) {
                    e.printStackTrace();
                    return false;
                }
            }
            }
            });
        }


@Override
public boolean onCreateOptionsMenu(Menu menu) {
    // Inflate the menu; this adds items to the action bar if it is present.
    getMenuInflater().inflate(R.menu.main, menu);
    return true;
}

}

  public String getTo(Object object) {

  }  

 }

我已经添加了activation.jar，mail.jar和additional.jar，甚至是manifest中的权限。我真的很不高兴我已经使用了asynctask但仍然没有工作。请帮助我。我是android的新手，我不知道下一步该做什么。

我认为您的 SendEmailAsyncTask.class.getName（）

存在问题

为什么不发送电子邮件？
