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

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

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

（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）在清单文件注册Receiver

   <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>
