我是否可以使用服务在后台发送电子邮件。。像在服务中一样,我使用Intent和ACTION\u SENDTO以及Uri数据mailto:recipient\u email,它在后台发送,无需任何用户干预。。或者通过默认的电子邮件应用程序,而不提示用户

然后您需要以编程的方式进行。这里有一个指南,因为该网站现在有一个域名抢占者

最好的解决方案是使用Gmail帐户发送电子邮件

一般来说:

  • 下载适用于android的mail.jar和activation.jar
  • 连接到GMail以获取OAuth令牌
  • 发送电子邮件
  • 这是密码

    请注意,要获取OAuth令牌,您需要一个活动,您必须询问用户要使用哪个帐户。应在OnCreate阶段检索令牌,并将其保存在首选项中。另见


    或者,您可以使用mail.jar,但必须向用户询问用户名和密码。
