129.s1-拦截黑名单的电话，Android Studio使用aidl

拦截电话需要权限

<uses-permission android:name="android.permission.CALL_PHONE"></uses-permission>
           

清除来电记录需要权限

<uses-permission
        android:name="android.permission.READ_CALL_LOG"></uses-permission>
    <uses-permission
        android:name="android.permission.WRITE_CALL_LOG"></uses-permission>
           

CallSafeService.java需要aidl来实现endCall()方法，内容观察者修改来电中黑名单的电话给删除，业务逻辑方法

使用aidl的步骤

1.再main下面创建一个aidl文件夹。

2.

再aidl目录下面创建一个包名的文件夹再将aidl文件拷贝到相关的目录下，NeighboringCellInfo也需要引入进来
