教你開啟自啟動程序! 在電腦的操作系統中都能在電腦開機後自啟動一些程序,在android平台也是可以的,那麼我們如何才能做到這樣的效果呢。
1、需要BroadcastReceiver
2、使用interfilter中的action:android.intent.action.BOOT_COMPLETED //當啟動手機系統啟動完成後就啟動此Receiver
功能:當手機系統啟動完成後,直接啟動某個程序或者Activity,這裡直接啟動某個程序
一下是代碼分析:
androidManifest.XML文件內容:

XML代碼
1. # < ?XML version="1.0" encoding="utf-8"?>

要啟動的Activity類:
Java代碼
1. # package cc.androidos.sms;
2. # import android.app.Activity;
3. # import android.os.Bundle;
4. # public class StartUp extends Activity {
5. # /** Called when the activity is first created. */
6. # @Override
7. # public void onCreate(Bundle savedInstanceState) {
8. # super.onCreate(savedInstanceState);
9. # setContentVIEw(R.layout.main);
10. # }
11. # }
# 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類:系統啟動後接受信息的類
Java代碼
1. # package cc.androidos.sms;
2. # import android.app.Activity;
3. # import android.app.PendingIntent;
4. # import android.content.BroadcastReceiver;
5. # import android.content.Context;
6. # import android.content.Intent;
7. # import android.Net.Uri;
8. # import android.util.Log;
9. # public class BootReceiver extends BroadcastReceiver
10. # {
11. # @Override
12. # public void onReceive( Context context, Intent intent )
13. # {
14. # if(intent.getAction().equals( Intent.ACTION_BOOT_COMPLETED )){
接上頁
15. # Log.d( ">>>>>>>>>>>>>>>>>>>>>>>>>>>>>>", "boot start................" );
16. # Log.d( ">>>>>>>>>>>>>>>>>>>>>>>>>>>>>>", "boot start................" );
17. # Log.d( ">>>>>>>>>>>>>>>>>>>>>>>>>>>>>>", "boot start................" );
18. # Log.d( ">>>>>>>>>>>>>>>>>>>>>>>>>>>>>>", "boot start................" );
19. # Log.d( ">>>>>>>>>>>>>>>>>>>>>>>>>>>>>>", "boot start................" );
20. # Log.d( ">>>>>>>>>>>>>>>>>>>>>>>>>>>>>>", "boot start................" );
21. # Log.d( ">>>>>>>>>>>>>>>>>>>>>>>>>>>>>>", "boot start................" );
22. # Intent i = new Intent(context,StartUp.class);
23. # i.setFlags( Intent.FLAG_ACTIVITY_NEW_TASK );
24. # //使用Receiver直接啟動Activity時候需要加入此flag,否則系統會出現異常
25. # context.startActivity( i );
26. #
27. # }
28. # }
29. # }
# 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
接上頁
# {
# @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直接啟動Activity時候需要加入此flag,否則系統會出現異常
# context.startActivity( i );
#
# }
# }

第一個運行完成後,關閉手機模擬器或者手機,然後啟動手機操作系統,啟動完成後StartUp Activity會自動運行。
流程: 系統啟動完成-------》通過androidManifest.XML了解到系統啟動完成後要啟動BootReceiver -------》BootReceiver 啟動StartUp Activity。
