Android拦截电话与短信（电话拒接/短信拒收）

前段时间领导说了这样一个需求：对特定的号码电话进行拦截、短信拒收，在百度了查阅了很多的资料，结果有点不尽人意。特别是AIDL通信接口废了老大劲。直接上过程

创建aidl通信接口直接在main目录新建aldl类型文件ITelephony即可，自动生成包名等等如图所示此处有坑：网上基本上都是让这样写

interface ITelephony {boolean endCall();void answerRingingCall();
}

这里导致有可能会导致项目编译错误，这里最好还是不要去网上粘贴aidl包名和ITelephony，尽量自己创建不要懒

// ITelephony.aidl
package com.android.internal.telephony;// Declare any non-default types here with import statementsinterface ITelephony {/*** Demonstrates some basic types that you can use as parameters* and return values in AIDL.*/void basicTypes(int anInt, long aLong, boolean aBoolean, float aFloat,double aDouble, String aString);boolean endCall();void answerRingingCall();
}

如果编译不通过重新编译一下就好。

根据需求需要配置权限如下：

<uses-permission android:name="android.permission.RECEIVE_SMS"></uses-permission>
<!-- 增加拦截电话的权限 -->
<uses-permission android:name="android.permission.PROCESS_OUTGOING_CALLS" />
<!-- 挂断手机的权限 -->
<uses-permission android:name="android.permission.CALL_PHONE"/>
<!-- 读取手机状态的权限 -->
<uses-permission android:name="android.permission.READ_PHONE_STATE" />
<!-- 读content的权限 -->
<uses-permission android:name="android.permission.READ_CONTACTS" />
<uses-permission android:name="android.permission.READ_SMS" />
<uses-permission android:name="android.permission.WRITE_SMS" />
<uses-permission android:name="android.permission.SEND_SMS" />
<uses-permission android:name="android.permission.READ_CALL_LOG" />
<uses-permission android:name="android.permission.WRITE_CALL_LOG" />
<uses-permission android:name="android.permission.BROADCAST_STICKY" />

我这里直接贴代码，注释我会写清楚的

}

好嘞这样就可以了，可以根据自己的需求改吧改吧就可以用了。目前在我的真机上的测试效果如下：

手机通讯录外的号码呼入拒接，短信拒收（在信息里面也找不到痕迹）
