Question

我想从我的服务运行中启动SMS和电子邮件应用程序。下面的代码在Activity中使用时工作，但是在Service中它给出了错误。请注意，如果我开始简单的活动，它可以在服务中正常工作。

subject="My currunt Position";
Intent intentemail = new Intent(Intent.ACTION_SEND);
intentemail.setType("message/rfc822");
intentemail.putExtra(Intent.EXTRA_SUBJECT, subject);
intentemail.putExtra(Intent.EXTRA_TEXT, returnMessageBody());
Intent mailer = Intent.createChooser(intentemail,  null);
mailer.addFlags(FLAG_ACTIVITY_NEW_TASK);
startActivity(mailer);
