我有一个问题因为我试图在我的新华为p9 lite上安装我的应用程序并且一切正常，但在关闭应用程序之后我的服务也应该在后台关闭。我在其他手机上安装了该应用程序并且运行正常。为什么？？？请帮忙。 P.S：手机上有android 6.0。
这是我的服务代码：
@Nullable

}

bluetoothAdapter.enable();
}

}
}, 0, 5, TimeUnit.SECONDS);
ScheduledExecutorService checkWeather = Executors.newScheduledThreadPool(1);
checkWeather.scheduleAtFixedRate(new Runnable(){
