android - 解绑服务但不销毁它

Question

在这里，我想使用名为 deadreckoning service 的服务来更新我的 UI，当此 Activity 停止时，我希望保持服务继续工作，所以我没有使用 unbind 方法，问题是，每次我销毁 fragment 时没有解除绑定(bind)方法的 UI，Logcat 给出错误，这是我的内存泄漏，实际上我在其他地方定义了 stopService，那么我该如何消除这个错误？我需要在绑定(bind)方法中放置一个预定义标志而不是 0 吗？以下是我的绑定(bind)代码:

    if (DeadReckoningService.isDeadReckoningStart) {
        Intent intent = new Intent(getActivity(), DeadReckoningService.class);
        getActivity().bindService(intent, connection, 0);
        serviceUpdateUI.post(runnable);
    }

谢谢你的回答，可能是我没把问题解释好。下面是一些关于环境的附加说明:

其实我是先用一个broadcastReceiver中的startService来启动的。然后在 Activity(RunFragment) 中使用 bindService 与这个后台服务通信并更新 UI。

当我关闭这个 runFragment 时，我不想停止服务，我仍然希望它在后台进行一些登录。所以我只想让它停止与 runFragment 的通信，所以我不使用 unbindService(因为它也会停止服务)。此时在 logcat 中，我得到了我的内存泄漏的错误信息。我想问一下如何避免这个错误信息。

那么我什么时候停止服务？当用户下次再次打开这个 runFragment 时，当用户按下停止按钮时，调用停止服务，通信和 UIupdate 的东西就结束了。

这是Logcat中的错误报告

Answer 1

绑定(bind)前使用startService
