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.aidlpackage 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：

我这里直接贴代码，注释我会写清楚的

           Cursor phone = cr.query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null,                    ContactsContract.CommonDataKinds.Phone.CONTACT_ID + " = " + contactId, null, null);            // 取得电话号码(可能存在多个号码)            while (phone.moveToNext()) {                String strPhoneNumber = phone.getString(phone.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));                String str1 = strPhoneNumber.replaceAll(" ", "");                String str2 = str1.replaceAll("-", "");                numList.add(str2);            }            phone.close();        }        cursor.close();        return numList;    }    @Override    protected void onDestroy() {        super.onDestroy();        //注销广播        if (null != mIncomingCallReceiver)            unregisterReceiver(mIncomingCallReceiver);    }}

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）
