Android：如果我使用SmsManager发送短信，它会自动重新发送失败的短信吗？

Question

如果我正在使用SmsManager从我的应用程序发送SMS，并且SMS无法发送，那么SmsManager是否会自动重试为我发送SMS-还是我必须在代码中自行管理？

Answer 1

no it does not.

if there is no signal to send a message and it fails.. the phone SHOULD automatically continue to try resending..

currently it simply reports that it has failed and puts it in a list of failed messages.

so, no...You can catch if the message was sent or not and repsond to these events.
