1.定義一個BroadcastReceiver

?

[java] view plaincopyprint?

public?class?BootReceiver?extends?BroadcastReceiver?{????

????public?void?onReceive(Context?ctx,?Intent?intent)?{????

????????Log.d("BootReceiver",?"system?boot?completed");????

????????//start?activity?? ??

????????String?action="android.intent.action.MAIN";????

????????String?category="android.intent.category.LAUNCHER";????

????????Intent?myi=new?Intent(ctx,CustomDialog.class);????

????????myi.setAction(action);????

????????myi.addCategory(category);????

????????myi.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);????

????????ctx.startActivity(myi);????

????????//start?service?? ??

????????Intent?s=new?Intent(ctx,MyService.class);????

????????ctx.startService(s);????

????}????

}????

public class BootReceiver extends BroadcastReceiver { public void onReceive(Context ctx, Intent intent) { Log.d("BootReceiver", "system boot completed"); //start activity String action="android.intent.action.MAIN"; String category="android.intent.category.LAUNCHER"; Intent myi=new Intent(ctx,CustomDialog.class); myi.setAction(action); myi.addCategory(category); myi.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK); ctx.startActivity(myi); //start service Intent s=new Intent(ctx,MyService.class); ctx.startService(s); } } ?

?

2.配置Receiver的許可,允許接收系統啟動消息，在AndroidManifest.xml中：

?

[xhtml] view plaincopyprint?

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

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

?

?

3.配置Receiver,可以接收系統啟動消息，在AndroidManifest.xml中

?

[xhtml] view plaincopyprint?

<receiver?android:name=".app.BootReceiver">????

????<intent-filter>????

????????<action?android:name="android.intent.action.BOOT_COMPLETED"/>????

????????<category?android:name="android.intent.category.HOME"?/>????

????</intent-filter>????

</receiver>???

<receiver android:name=".app.BootReceiver"> <intent-filter> <action android:name="android.intent.action.BOOT_COMPLETED"/> <category android:name="android.intent.category.HOME" /> </intent-filter> </receiver> ?

?

?

4.啟動模擬器，可以看到系統啟動后，彈出一個對話框。
