本文介绍了如何使Android应用程序在设备开机时自动启动。主要涉及两个步骤：一是创建一个继承BroadcastReceiver的类，二是配置AndroidManifest.xml文件，添加必要的权限和注册receiver。

1.编写目标类并继承BroadcastReceiver

package com.example.gsensortester;

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

public class BootCompletedReceiver extends BroadcastReceiver{

	@Override
	public void onReceive(Context arg0, Intent arg1) {
		final Context mContext = arg0;
		Log.d("BootCompletedReceiver", "recevie boot completed ... ");  
		if(Intent.ACTION_BOOT_COMPLETED.equals(arg1.getAction()))  {
                     Log.d("BootCompletedReceiver", "Hello,world... ");
               }			
	}

}

上列在收到开机广播之后输出"Hello,world".

2.AndroidManifest.xml中添加权限和注册

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

    <uses-sdk
        android:minSdkVersion="14"
        android:targetSdkVersion="19" />

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

    <application
        android:allowBackup="true"
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name"
        android:theme="@style/AppTheme" >
		<receiver android:name=".BootCompletedReceiver">  
		    <intent-filter>    
		        <action android:name="android.intent.action.BOOT_COMPLETED" />
		        <category android:name="android.intent.category.DEFAULT" />    
		    </intent-filter>  
		</receiver>         
    </application>

</manifest>

主要是向其中注册广播接收器：

		<receiver android:name=".BootCompletedReceiver">  
		    <intent-filter>    
		        <action android:name="android.intent.action.BOOT_COMPLETED" />
		        <category android:name="android.intent.category.DEFAULT" />    
		    </intent-filter>  
		</receiver>

以及添加开机广播接收的权限：

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