Android端（等待呼叫）程序化

我正在为呼叫中心的人构建某种类型的util应用程序。我必须在等待呼叫时执行操作

假设ABC试着打电话给我，我接了电话，同时XYZ也试着打电话给我，那么XYZ呼叫将移动到等待状态，直到我做出一些决定，如结束ABC呼叫或拒绝XYZ呼叫

到目前为止，我能够检测到ABC何时与我交谈，XYZ何时打电话给我——我也会收到同样的事件。在这种情况下，如果我调用/运行disconnectCall方法，那么我的第一个调用是get end up，但我希望自动结束第二个调用，而不是第一个调用

查看下面我的代码，该代码检测正在等待的呼叫过多onNewIncomingCallReceived当新呼叫进入等待状态时，会添加此日志

public class CallListenerReceiver extends BroadcastReceiver {

//The receiver will be recreated whenever android feels like it.  We need a static variable to remember data between instantiations
private static int lastState = TelephonyManager.CALL_STATE_IDLE;
private static Date callStartTime;

private boolean isUserOnCall = false;
private static final String TAG = "CallListenerReceiver";
private static String savedNumber;  //because the passed incoming is only valid in ringing

@Override
public void onReceive(Context context, Intent intent) {

    //We listen to two intents.  The new outgoing call only tells us of an outgoing call.  We use it to get the number.
    if (intent.getAction().equals("android.intent.action.NEW_OUTGOING_CALL")) {
        savedNumber = intent.getExtras().getString("android.intent.extra.PHONE_NUMBER");
    } else {
        String stateStr = intent.getExtras().getString(TelephonyManager.EXTRA_STATE);
        String number = intent.getExtras().getString(TelephonyManager.EXTRA_INCOMING_NUMBER);
        int state = 0;

有谁能帮我自动结束第二次通话，然后用户已经在和其他人通话了。在过去的三天里，我一直在寻找解决方案，但我没有得到它
