我们怎样才能电子邮件确认发送或由Android的任何邮件客户端丢弃。

块引用>

幸运的是，这是不支持的。

如果您要发送通过 ACTION_SEND 数据，请允许用户与数据做，因为他们选择，其中包括放弃发送操作。你没有方法来确定是否该用户或不发送的信息。

How can we get confirmation of Email send or discarded by any mail client of android.

I have tried startActivityForResult() but it not works. It returns Intent=Null and Resultcode=0 every time while send or discard pressed.

Thanks in Advance for your response.

Fortunately, this is not supported.

If you are sending data via ACTION_SEND, please allow the user to do with that data as they choose, including abandoning the "send" operation. You do not have a way to determine if the user does or does not "send" the information.
