上一节已经介绍过BroadcastReceiver实现实时监听电量的功能,这节就来介绍一下假设实现开机自己主动启动的功能,这个比监听电量还简单不少
(1)在清单文件注冊权限
(2)实现 BroadcastReceiver接口
package com.example.g04_broadcastreciver04;import android.content.BroadcastReceiver;import android.content.Context;import android.content.Intent;public class BootComplete extends BroadcastReceiver { @Override public void onReceive(Context context, Intent intent) { // TODO Auto-generated method stub Intent intent2=new Intent(context,MainActivity.class); intent2.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK); context.startActivity(intent2); }}(3)在清单文件注冊Receiver
