如何检测在android系统掉话 [英] How to detect a call Drop in android

问题描述

我正在写的电话交谈中对后台运行，并记录坐标到一个文件中有谈话结束后，我知道的Andr​​oid电话API可以检测到一个呼叫手动断开用户*一个应用程序（纠正我，如果我'错了）*，

I'm writing an app that runs on background during a telephone conversation and logs the coordinates to a file after the conversation has end,I know Android telephony API can detect a call manual disconnect by user*(correct me,if I'm wrong)*,

但我要的是知道服务断线是否因导致调用下降，有一个方法或API我可以用它来实现这一目标，

But what I want is to know whether the service disconnection have caused due to call drop,is there a way or an API I can use to achieve this,

所有我需要的是通过编程区分断开连接的呼叫和掉话。

All what I need is to programmatically differentiate a disconnected call and a dropped call.

请帮助..

推荐答案

试试这个code，但我不知道..

Try this code, but I am not sure..

private getCallFailedString(Call call) { 

    Phone phone = PhoneApp.getInstance().phone; 
    Connection c = call.getEarliestConnection(); 

    Connection.DisconnectCause cause = c.getDisconnectCause(); 

    switch (cause) { 
        case BUSY: 
        break; 

    case CONGESTION: 
         break; 

    case LOST_SIGNAL: 
         break; 

    case LIMIT_EXCEEDED: 
         break; 

    case POWER_OFF: 
         break; 

    case SIM_ERROR: 
         break; 

    case OUT_OF_SERVICE: 
         break; 

    default: 
         break; 

    } 

}
