教你开启自启动程序

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代码 
# <?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>  

# <?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：



Java代码 
# 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);  
#     }  
# }  

# 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



Java代码 
# 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 );  
#             
#         }  
#     }  
# }  

# 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。
