Android开发之使用BroadcastReceiver实现开机自动启动（源代码分享）

From:/article/1337154.html

上一节已经介绍过BroadcastReceiver实现实时监听电量的功能，这节就来介绍一下如果实现开机自动启动的功能，这个比监听电量还简单不少

（1）在清单文件注册权限

[java] view
plaincopy

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

（2）实现 BroadcastReceiver接口

[java] view
plaincopy

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）在清单文件注册Receiver

[java] view
plaincopy

<receiver android:name="com.example.g04_broadcastreciver04.BootComplete" >

<intent-filter>

<action android:name="android.intent.action.BOOT_COMPLETED" >

</action>

<category android:name="android.intent.category.HOME" >

</category>

</intent-filter>

</receiver>
