package com.rongfzh.yc;

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

public class BootReceiver extends BroadcastReceiver{
     
    @Override 
    public void onReceive(Context context, Intent intent){
        //接收安装广播
        if (intent.getAction().equals("android.intent.action.PACKAGE_ADDED")) {  
            String packageName = intent.getDataString();  
            System.out.println("安装了:" +packageName + "包名的程序");    
        }  
        //接收卸载广播 
        if (intent.getAction().equals("android.intent.action.PACKAGE_REMOVED")) {  
            String packageName = intent.getDataString();  
            System.out.println("卸载了:"  + packageName + "包名的程序");
