Question

我在启动宽度上启动服务广播接收器：

public class Autostart extends BroadcastReceiver {
    @Override
    public void onReceive(Context context, Intent arg1) {
        Intent intent = new Intent(context, MyService.class);
        MyService.setContext(context);
        context.startService(intent);
    }
}

这有效，当我启动手机时，服务正在后台运行。然后我想从我的GUI停止/启动/重启服务：

Intent intent = new Intent(MyService.getContext(), MyService.class);
getActivity().stopService(intent);

但它不会杀死任务。我认为当Context相同时，这必须工作，所以我制作了一个静态内容持有者，但它不起作用。

请注意，我可以启动该服务，并从该代码轻松停止已启动的服务。

如何停止自动启动/后台服务？

用于调用任何Android后台服务执行以下操作

首先添加create a fetch服务类然后调用它

public class FetchUnreadMailService extends Service {

    private NotificationManager mNotificationManager;
    private int SIMPLE_NOTFICATION_ID;
    private Timer myTimer;
    Session mySession;      
    int unread_count = 0;

    @Override
    public IBinder onBind(Intent arg0) {
        // TODO Auto-generated method stub
        return null;
    }

    @Override
    public void onCreate() {
        super.onCreate();

        myTimer = new Timer();
        myTimer.schedule(new TimerTask() {
            @Override
            public void run() {

                    mySession = new Session();
                     if(mySession.getStatus()){
                            APIHelper api = new APIHelper();
                            unread_count =  (Integer) api.getMailBoxNotification(mySession.getUserId());
                            }
                        if(unread_count>0){
                            mNotificationManager = (NotificationManager)getSystemService(NOTIFICATION_SERVICE);
                            Intent notifyIntent = new Intent(FetchUnreadMailService.this,MailBox.class);
                            Context context = getApplicationContext();
                            CharSequence contentTitle = "New Mail";
                            CharSequence contentText = "You Have ("+ unread_count +") unread mails";
                            PendingIntent intent = PendingIntent.getActivity(FetchUnreadMailService.this, 0,notifyIntent, android.content.Intent.FLAG_ACTIVITY_NEW_TASK);
                            final Notification notifyDetails = new Notification(R.drawable.youtube,"New Alert, Click Me!",System.currentTimeMillis());  
                            notifyDetails.setLatestEventInfo(context, contentTitle, contentText, intent);
                            notifyDetails.flags= Notification.FLAG_AUTO_CANCEL;//for auto cancel notification
                            mNotificationManager.notify(SIMPLE_NOTFICATION_ID, notifyDetails);  
                            }   




            }

        }, 0, 30000);

    }

    @Override
    public void onDestroy() {
        super.onDestroy();
        Toast.makeText(this, "Service destroyed ...", Toast.LENGTH_LONG).show();
    }






}

创建此类后，请通过以下

调用它

startService(new Intent(Home.this,FetchUnreadMailService.class));
