开机自动启动 Server

1.首先开机启动后系统会发出一个Standard Broadcast Action,名字叫Android.intent.action.BOOT_COMPLETED,这个Action只会发出一次。

2.构造一个IntentReceiver类,重构其抽象方法onReceiveIntent(Context context, Intent intent),在其中启动你想要启动的Service。

3.在AndroidManifest.xml中,首先加入来获得BOOT_COMPLETED的使用许可,然后注册前面重构的IntentReceiver类,在其中加入 ,以使其能捕捉到这个Action。

AndroidManifest.xml

    <uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED"></uses-permission>       <receiver android:name=".OlympicsReceiver" android:label="@string/app_name">            <intent-filter>               <action android:name="android.intent.action.BOOT_COMPLETED" />               <category android:name="android.intent.category.LAUNCHER" />            </intent-filter>        </receiver>  

OlympicsReceiver.java

    public class OlympicsReceiver extends IntentReceiver        {           /*要接收的intent源*/          static final String ACTION = "android.intent.action.BOOT_COMPLETED";           public void onReceiveIntent(Context context, Intent intent)            {               if (intent.getAction().equals(ACTION))                {                         context.startService(new Intent(context,                               OlympicsService.class), null);//启动倒计时服务                    Toast.makeText(context, "OlympicsReminder service has started!", Toast.LENGTH_LONG).show();               }           }       }  

注意:现在的IntentReceiver已经变为BroadcastReceiver,OnReceiveIntent为onReceive。所以java这边的代码为:

public class OlympicsReceiver extends BroadcastReceiver   {       /*要接收的intent源*/      static final String ACTION = "android.intent.action.BOOT_COMPLETED";       public void onReceive(Context context, Intent intent)        {           if (intent.getAction().equals(ACTION))            {                     context.startService(new Intent(context,                           OlympicsService.class), null);//启动倒计时服务                Toast.makeText(context, "OlympicsReminder service has started!", Toast.LENGTH_LONG).show();               //这边可以添加开机自动启动的应用程序代码           }       }   }
