アップデートの３０秒程度intentservceが動かない件について

runしたあとの30~40秒の間foregroundのserviceからホームボタンを押したときにIntentServiceを使用できなくなっています。仕様ですか？

#コード１service

@Override
public void onCreate() {

    super.onCreate();
    final SharedPreferences sn=getSharedPreferences("today",MODE_MULTI_PROCESS);
    final SharedPreferences.Editor editor=sn.edit();
    editor.putInt("start",1).commit();

    m_HomeButtonReceive = new HomeButtonReceive();
    IntentFilter iFilter = new IntentFilter();
    iFilter.addAction(Intent.ACTION_CLOSE_SYSTEM_DIALOGS);
    this.registerReceiver(m_HomeButtonReceive, iFilter);




}

public int onStartCommand(Intent intent, int flags, int startId) {
    Notification notification=new NotificationCompat.Builder(this)
            .setSmallIcon(R.drawable.icon)
            .setContentText("×××" )
            .setContentTitle("×××").build();
    NotificationManager manager=(NotificationManager)getSystemService(Context.NOTIFICATION_SERVICE);
    manager.notify(1,notification);


    startForeground(1,notification);


    return START_STICKY;


}

@Override
public IBinder onBind(Intent intent) {
return null;
}

public class HomeButtonReceive extends BroadcastReceiver {


    @Override
    public void onReceive(Context arg0, Intent arg1) {
 
        Bundle bundle = (arg1 == null) ? null : arg1.getExtras();
        Object o = (bundle == null) ? null : bundle.get("reason");
        Toast.makeText(arg0.getApplicationContext(),(String)o,Toast.LENGTH_LONG).show();
        if (((String)o).equals("homekey")) {//o instanceof String &&

             if (sn.getInt("×××", 0) != 1)
                startService(new Intent(getApplicationContext(), APPintentservice.class));
        }
    }
}

#コード２ intentservice
public class APPintentservice extends IntentService {

public APPintentservice(String name) {
    super(name);
}

public APPintentservice() {
    super("APPintentservice");
}


@Override
protected void onHandleIntent(Intent data) {
    SystemClock.sleep(100);
    Intent intent = new Intent();
    intent.setAction("×××");
    sendBroadcast(intent);
}

}

自分のコードから抜粋してきたので抜けがあるかもしてません
