Android 开发 — 开机自启动

Android 的开机自启动是通过捕捉开机结束的广播来实现的，手机的启动完后会给出一个BroadcastReceiver，在自己的程序中捕捉即可。

 

AutoBootReceiver.java 文件：

 

package com.ldq.auto.boot;

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

public class AutoBootReceiver extends BroadcastReceiver {

	@Override
	public void onReceive(Context context, Intent intent) {
		// TODO Auto-generated method stub
		if (intent.getAction().equals(Intent.ACTION_BOOT_COMPLETED)) {
			Log.i("------", "AutoBootReceiver auto boot");
			Intent in = new Intent(context, ExAutoBoot.class);
			in.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);//添加Flags必不可少，否则报错
			context.startActivity(in);
		}
	}
}

 ExAutoBoot.java 文件： 

package com.ldq.auto.boot;

import android.app.Activity;
import android.os.Bundle;
import android.util.Log;

public class ExAutoBoot extends Activity {
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        Log.i("------","ExAutoBoot auto boot");
    }
}

 AndroidManifest.xml 文件：

 

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
	package="com.ldq.auto.boot" android:versionCode="1"
	android:versionName="1.0">
	<application android:icon="@drawable/icon" android:label="@string/app_name">
		<activity android:name=".ExAutoBoot" android:label="@string/app_name">
			<intent-filter>
				<action android:name="android.intent.action.MAIN" />
				<category android:name="android.intent.category.LAUNCHER" />
			</intent-filter>
		</activity>
		<receiver android:name="AutoBootReceiver">
			<intent-filter>
				<action android:name="android.intent.action.BOOT_COMPLETED"></action>
			</intent-filter>
		</receiver>
	</application>
	<uses-sdk android:minSdkVersion="4" />
	<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED"></uses-permission>
</manifest> 

 

教你开启自启动程序！ 在电脑的操作系统中都能在电脑开机后自启动一些程序，在Android平台也是可以的，那么我们如何才能做到这样的效果呢。 
1、需要BroadcastReceiver 
2、使用interfilter中的action：android.intent.action.BOOT_COMPLETED  //当启动手机系统启动完成后就启动此Receiver 

功能：当手机系统启动完成后，直接启动某个程序或者Activity，这里直接启动某个程序 

一下是代码分析： 

AndroidManifest.xml文件内容：

# <?xml version="1.0" encoding="utf-8"?>
# <manifest xmlns:android="http://schemas.android.com/apk/res/android"
#       package="cc.androidos.sms"
#       android:versionCode="1"
#       android:versionName="1.0.0">
#     <application android:icon="@drawable/icon" android:label="@string/app_name">
#         <activity android:name=".StartUp"
#                   android:label="@string/app_name">
#             <intent-filter>
#                 <action android:name="android.intent.action.MAIN" />
#                 <category android:name="android.intent.category.LAUNCHER" />
#             </intent-filter>
#         </activity>
#        
#         <receiver android:name=".BootReceiver">
#         <intent-filter>
#          <action android:name="android.intent.action.BOOT_COMPLETED" />
#         </intent-filter>
#         </receiver>
#         <service android:name=".StartService"/>
#     </application>
# </manifest> 

 要启动的Activity类：

# package cc.androidos.sms;
# import android.app.Activity;
# import android.os.Bundle;
# public class StartUp extends Activity {
#     /** Called when the activity is first created. */
#     @Override
#     public void onCreate(Bundle savedInstanceState) {
#         super.onCreate(savedInstanceState);
#         setContentView(R.layout.main);
#     }
# } 

 Receiver类：系统启动后接受信息的类

# package cc.androidos.sms;
# import android.app.Activity;
# import android.app.PendingIntent;
# import android.content.BroadcastReceiver;
# import android.content.Context;
# import android.content.Intent;
# import android.net.Uri;
# import android.util.Log;
# public class BootReceiver extends BroadcastReceiver
# {
#     @Override
#     public void onReceive( Context context, Intent intent )
#     {
#         if(intent.getAction().equals( Intent.ACTION_BOOT_COMPLETED )){
#             Log.d( ">>>>>>>>>>>>>>>>>>>>>>>>>>>>>>", "boot start................" );
#             Log.d( ">>>>>>>>>>>>>>>>>>>>>>>>>>>>>>", "boot start................" );
#             Log.d( ">>>>>>>>>>>>>>>>>>>>>>>>>>>>>>", "boot start................" );
#             Log.d( ">>>>>>>>>>>>>>>>>>>>>>>>>>>>>>", "boot start................" );
#             Log.d( ">>>>>>>>>>>>>>>>>>>>>>>>>>>>>>", "boot start................" );
#             Log.d( ">>>>>>>>>>>>>>>>>>>>>>>>>>>>>>", "boot start................" );
#             Log.d( ">>>>>>>>>>>>>>>>>>>>>>>>>>>>>>", "boot start................" );
#             Intent i = new Intent(context,StartUp.class);
#             i.setFlags( Intent.FLAG_ACTIVITY_NEW_TASK );
#                                             //使用Receiver直接启动Activity时候需要加入此flag，否则系统会出现异常
#             context.startActivity( i );
#           
#         }
#     }
# } 

 第一个运行完成后，关闭手机模拟器或者手机，然后启动手机操作系统，启动完成后StartUp Activity会自动运行。
