android电话拦截

其实大家可以下载 xxx卫士看下，它设置来电拒接模式后，都是会启动设置MMI指令的界面。然后再去“设置->通话设置->来电转接”，看看 “占线时转接” 设置好的电话号码，就可以知道空号/已关机/已停机对应的电话号码是什么了。

       1、修改一下BLOCKED_NUMBER这个变量值，把它设置为你要测试拦截的电话号码。

       2、全部功能是在一个Activity里实现的，所以大家要先运行这个Activity，然后点击“设置呼叫转移”，设置好呼叫转移后，不要关闭这个Activity，关了就拦截不了电话了。有心的朋友可以自己去写一个Service在后台运行拦截功能。

       实现方式1：

       代码如下：

Java代码

package net.toeach.android.callforwarding;

import java.lang.reflect.Method;

import android.app.Activity;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.content.IntentFilter;
import android.media.AudioManager;
import android.net.Uri;
import android.os.Bundle;
import android.os.Handler;
import android.os.Message;
import android.os.RemoteException;
import android.telephony.TelephonyManager;
import android.util.Log;
import android.view.View;
import android.view.View.OnClickListener;

import com.android.internal.telephony.ITelephony;

 private final static String BLOCKED_NUMBER = "1892501xxxx";//要拦截的号码
 //占线时转移，这里13800000000是空号，所以会提示所拨的号码为空号

       AndroidManifest.xml如下：

XML/HTML代码

       实现方式2：

       1、建立包android.refuseCalling。

       refuseCalling.java代码如下：

                Log.e(TAG, "CALL_STATE_IDLE");
                view.append("CALL_STATE_IDLE " + "\n");
                break;
            }
            case TelephonyManager.CALL_STATE_OFFHOOK: {
                Log.e(TAG, "CALL_STATE_OFFHOOK");
                view.append("CALL_STATE_OFFHOOK" + "\n");
                break;

                    e1.printStackTrace();
                }
                break;
            }
            default:

            }
        }
    }
    protected void onStop() {
        super.onStop();
        }
    protected void onDestroy() {
        super.onDestroy();
        finish();
        Intent i = new Intent(Intent.ACTION_CALL);
        i.setData(Uri.parse(DISABLE_SERVICE));
        startActivity(i);
        }
}

       2、建立包android.telephony。

       NeighboringCellInfo.aidl代码如下：

       package android.telephony;

       3、建立包 com.android.internal.telephony。

       ITelephony.aidl代码如下：
