Android接聽、掛斷電話

新建一個名為ITelephony的aidl文件，注意包名不能改變，因為是通過反射方式來實現接聽和掛斷的

ITelephony.aidl
package com.android.internal.telephony;
interface ITelephony{
 boolean endCall();
 void answerRingingCall();
}

public class CallManager {
 private static CallManager instance = null;

 private static final String MANUFACTURER_HTC = "HTC";

 instance = new CallManager();
 }

 }
