替换传输。发送（消息）；使用下面的代码应该可以工作

   Transport transport = session.getTransport("smtp");
    transport.connect("smtp.gmail.com", 587, _user, _pass);
    transport.sendMessage(msg, msg.getAllRecipients());

问题是我所在校园的wifi网络阻止了电子邮件的发送。当我使用3G时，它已经工作了。

嘿，你的代码非常完美，因为我使用了这段代码，所以你需要为网络错误异常添加一个线程策略在你的onCreate（）方法中添加两行以下的内容。

StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder()
            .permitAll().build();
    StrictMode.setThreadPolicy(policy);

如果在sendEmail（）的catch块中放置一条日志消息，您将了解问题所在，基于此，您可以对代码进行更改

我面临的另一个问题是，我调用方法以在主线程中发送邮件，您可以创建一个单独的线程来调用邮件操作，它将像一个符咒一样工作。

发布您的错误，如果您没有收到任何错误，那么您的凭证可能是错误的。我没有收到任何错误，并且我的电子邮件和密码是正确的。有人可以试一试吗？@user3123469您完成了这个任务了吗？…有人解决了这个问题了吗？我也有同样的问题，我正在使用相同的代码，这是我的问题，所以我没有错误。我在清单中定义了凭据权限和internet权限，但在我的收件箱中仍然没有收到邮件………您确定您与internet？，然后调试应该给我们一些ClueBug你的应用程序，也许我们会得到一些Clue有人解决了这个问题我也有相同的问题我使用相同的代码这里是我的问题，所以我没有错误在清单中定义了凭据权限和internet权限，但我的收件箱中仍然没有收到邮件。。。。。。。。。。。。
