取回通话时间从Calllog使用BroadcastListener通话结束后， [英] Fetching Call duration from Calllog after call ends using BroadcastListener

问题描述

我要尝试并获得通话时间在通话结束后。我有一个广播监听器，使用电话管理器保持的电话状态轨迹，那就是摘机，空闲和所有。使用该接收机，可以找出当呼出已经完成。当通话结束后，我启动服务来获取最后一个电话的通话时间。但是，我得到的价值在于previous调用，而不是刚刚完成的一个。我想我从calllog DB之前它是由手机更新获取。因为如果我以后调用相同的功能，获取的价值，它给了我正确的时间..我应该以某种方式将在启动该服务之前的延迟？如果是的话，怎么怎么样拖了那么久？

I need to try and get the call duration after a call has ended. I have a broadcast listener which using telephony manager keeps track of the phone states, that is 'offhook', 'idle' and all. Using this receiver i can find out when a outgoing call has been completed. Upon completion of a call, i start a service to fetch the call duration of the last call. However, the value that i get is that of the previous call and not the one that just completed. I think i'm fetching from the calllog DB even before it was updated by the phone. Because if i later call the same function and fetch the value, it gives me the correct time.. Should i somehow put in a delay before starting the service? If yes, how and how much delay?

推荐答案

我想通了，如何做到这一点。我确信它取出由calllog该服务已启动约2秒通话结束之后。这样一来，我得到正确的值，而不是作为calllog被随后更新了previous通话时间的价值。

I figured out how to do it. I made sure the service which fetches from the calllog is started about 2 seconds after the call was ended. This way, I get the correct value and not the previous call duration value as the calllog is updated by then.
