CALL_STATE_IDLE多次调用？

Question

我创建了一个记录所有来电和去电的通话记录应用程序。应用程序运行完美我已经测试过了。我需要为录制的文件发送背景电子邮件（没有使用JAVAMAIL的用户发明）。我有工作代码用于发送带附件的邮件。我创建了收听PHONE_STATE和NEW_OUTGOING_CALL的广播接收器。广播接收器启动/停止根据电话状态更改记录服务。我的问题是如何整合我的电子邮件发送代码与应用程序。我知道我必须在CALL_STATE_IDLE中调用邮件发送方法。但由于该方法多次调用，我无法这样做。

我感到困惑的是CALL_STATE_IDLE是在后台发送电子邮件的正确位置，因为它多次出现。

对于来电电话状态是 CALL_STATE_RINGING CALL_STATE_OFFHOOK CALL_STATE_IDLE

对于拨出电话状态是 CALL_STATE_IDLE CALL_STATE_OFFHOOK CALL_STATE_IDLE

任何帮助PLZ .. 提前谢谢
