直接发送电子邮件没有意图
任何人都可以建议我如何发送电子邮件，而不使用意图或打开另一个Android应用程序。 我希望一旦我点击发送按钮就可以直接发送电子邮件。 我必须使用特定的office365电子邮件发送消息。 我应该使用一些API或SMTP等？
有一种简单的方法可以在我的android应用程序上应用此功能吗？
发送邮件是Android中的一个关键功能，也是一个简单的功能。
您也可以使用Intent发送邮件，但这需要用户界面，但这里的要求与通过使用GMail SMTP和JavaMail API无意发送电子邮件的要求不同。 使用GMail的SMTP服务器发送电子邮件非常简单且容易。
因此，您可以单击以检查完整示例：在Android中发送邮件而不使用意图
希望这会帮助你作为你的要求。
通过下面的链接。 这就是你真正想要的例子http://www.edumobile.org/android/send-email-on-button-click-without-email-chooser/
地狱@APX，下面是拖拽类，它可以帮助你在没有任何图书馆的情况下发送单个或多个用户的电子邮件，我想这会帮助你，

你可以像下面一样使用
MailSender sender = new MailSender("" + authEmail, "" + authPwd);
sender.sendMail("" + subject,
"" + prepareMailText(name),
"" + authEmail, "WeMeal Team",
"" + emailList); //email list send comma separated string like ("a@gmail.com,b@dahs.com")
