我试图在清醒的广播接收器中使用此背景电子邮件发件人代码（https://github.com/kristijandraca/BackgroundMailLibrary）发送电子邮件但在进行一些调整时我了解到，由于某种原因，当手机被锁定时它无法再发送电子邮件和wifi上。这是相关代码和错误报告。我将不胜感激任何建议将不胜感激。 在错误报告中，我将所有与日期不同的部分加粗，以便于阅读

如果网络可用，请随时拨打电话：
if(new NetworkConnection(this).isConnectionAvailable())

sendEmail();
}
这是发件人：
private void sendEmail() {

mail.setToMail("to mail address");
mail.setSubject("Subject");
mail.setMailDescription("Description");
mail.addAttachment("file path")// if attachment is there
try {
mail.send();
} catch (Exception e) {
e.printStackTrace();
Log.v(Email_Tag, ""+e);
}
}
