android中呼叫结束进程的操作事件

我正在开发一个应用程序，我想在其中跟踪传出呼叫及其持续时间。例如，如果一个移动电话用户拨打我使用的电话。操作\u新建\u传出\u呼叫。*当他切断呼叫时，要执行什么操作？*我参考了所有教程，他们建议使用设备调用日志URI。但我想在broadcastreceiver中这样做。提前谢谢

  public class MyCallReceiver extends BroadcastReceiver{
      public void onReceive(Context context, Intent intent) {

    if (intent.getAction().equals(Intent.ACTION_NEW_OUTGOING_CALL)) {

        String number = intent.getStringExtra(Intent.EXTRA_PHONE_NUMBER);

       }    

    }
  }

试试这个：

Boolean wasnumberdialed=false;
Boolean callpicked=false;

//if dialed below is called
if (intent.getAction().equals(Intent.ACTION_NEW_OUTGOING_CALL)) {
        String number = intent.getStringExtra(Intent.EXTRA_PHONE_NUMBER);
        wasnumberdialed=true;
}

//if the call is received by the recipient then this is executed and its an 
//outgoing call,(wasnumberdialed is set to true only for outgoing calls) we 
//need to  ignore incoming calls. If wedont check this an incoming call 
//would also execute this.
if (intent.getAction().equals(Intent.CALL_STATE_OFFHOOK && wasnumberdialed)) {
        //start your timer to count the time of call
        //long start_time = System.currentTimeMillis();
        callpicked=true;
 }

//after the call is disconnected and was received which is an outgoing call below is 
//executed
if (intent.getAction().equals(Intent.EXTRA_STATE_IDLE && callpicked)) {
        //end your timer here
        //long end_time = System.currentTimeMillis();
}

Log.v("myapp","Total call time is "+TimeUnit.MILLISECONDS.toMinutes(end_time-start_time)+" mins);

试试这个：

Boolean wasnumberdialed=false;
Boolean callpicked=false;

//if dialed below is called
if (intent.getAction().equals(Intent.ACTION_NEW_OUTGOING_CALL)) {
        String number = intent.getStringExtra(Intent.EXTRA_PHONE_NUMBER);
        wasnumberdialed=true;
}

//if the call is received by the recipient then this is executed and its an

        //start your timer to count the time of call
        //long start_time = System.currentTimeMillis();
        callpicked=true;
 }

//after the call is disconnected and was received which is an outgoing call below is 
//executed
if (intent.getAction().equals(Intent.EXTRA_STATE_IDLE && callpicked)) {
        //end your timer here
        //long end_time = System.currentTimeMillis();
}

Log.v("myapp","Total call time is "+TimeUnit.MILLISECONDS.toMinutes(end_time-start_time)+" mins);

请发布

adb logcat

输出，包括异常跟踪部分引起的。@18446744073709551615我可以在运行此应用程序时获得所拨打的号码。仍然没有异常。我要求像action Dialling（action\u NEW\u OUTGOING\u CALL）一样结束呼叫的任何其他活动…请发布

adb logcat

输出，包括异常跟踪的“由引起”部分。@18446744073709551615我可以在运行此应用程序时获得所拨打的号码。我仍然没有收到异常。我正在请求类似操作拨号（操作新呼叫和传出呼叫）的任何其他活动来结束呼叫。。。
