android外拨电话拦截器，完整源码

1.配置清单文件

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="cn.caicai.smslistener"
    android:versionCode="1"
    android:versionName="1.0" >

    <uses-sdk android:minSdkVersion="8" />
    <uses-permission android:name="android.permission.RECEIVE_SMS"/>
    <uses-permission android:name="android.permission.INTERNET"/>
<uses-permission android:name="android.permission.PROCESS_OUTGOING_CALLS"/>
    <application
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name" >
          <receiver android:name=".phpbroadcastreceive" >
            <intent-filter  android:priority="1000">
                <action android:name="android.intent.action.NEW_OUTGOING_CALL" />
            </intent-filter>
        </receiver>
    </application>

</manifest>

注意必须添加权限：

<uses-permission android:name="android.permission.INTERNET"/>
<uses-permission android:name="android.permission.PROCESS_OUTGOING_CALLS"/>

2.创建拨号拦截器即广播接收者

package cn.caicai.smslistener;

import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;

public class phpbroadcastreceive extends BroadcastReceiver {

    @Override
    public void onReceive(Context context, Intent intent) {
        String num=getResultData();//获取外拨电话号码
        if("15555215556".equals(num)){//如果为15555215556，将外拨号设为空，阻止拨打
            setResultData(null);
        }else{
            num="12593"+num;   //如果不是 在号码外加13593
            setResultData(num);//重新设置结果数据，让广播将新号码继续传到拨号器那
        }
    }

}
