android 后台service开机自启动

比如说，新闻客户端，IM聊天工具，关机开机之后，需要后台的服务启动，来收到最新的推送或者消息。或者这个service要做其他事情，总之要能够开机自启。每当服务启动的时候，我们启动一个通知栏，代码如下：

public class MyService  extends Service{@Overridepublic IBinder onBind(Intent arg0) {// TODO Auto-generated method stubreturn null;}@Overridepublic void onCreate() {// TODO Auto-generated method stubsuper.onCreate();Notification notification = new Notification(R.drawable.ic_launcher, "myService", System.currentTimeMillis());Intent notificationIntent  = new Intent(this,MainActivity.class);PendingIntent pendingIntent = PendingIntent.getActivity(getApplicationContext(), 0, notificationIntent, 0);notification.setLatestEventInfo(getApplicationContext(), "this is title ", "this is content ", pendingIntent);startForeground(1, notification);Log.e("myService", "onCreate");}}

界面很简答，start这个service就行，主要是设置权限：

 <service android:name = ".MyService">            </service>                      <receiver android:name=".BootBroadcastReceiver" >            <intent-filter>                <action android:name="android.intent.action.BOOT_COMPLETED"/>                <category android:name="android.intent.category.HOME" />            </intent-filter>        </receiver>

用一个广播来接收，开机的Intent，收到这个广播之后，直接启动service就行了。

public class BootBroadcastReceiver extends BroadcastReceiver {    static final String action_boot="android.intent.action.BOOT_COMPLETED";      @Override    public void onReceive(Context context, Intent intent) {        if (intent.getAction().equals(action_boot)){             Intent intentService = new Intent(context, MyService.class);        context.startService(intentService);        }     } }

好了，代码已经完成了，除了主Activity，你自己去启动就可以了，记得添加权限：

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

记得要在安全中心里设置，这个应用开机自启哦。
