好的，所以我构建了一个使用远程服务进行实时GPS跟踪的应用程序。我使用以下代码启动并绑定到服务。
远程服务使用aidl，设置通知图标，运行GPS和locationListener。在onLocationChanged中，处理程序通过回调将数据发送回调用者。非常直接来自在线示例和资源。
即使应用关闭，我也想让服务继续运行。当应用程序重新启动时，我希望应用程序再次绑定到服务（如果正在运行则使用现有服务）并再次从跟踪器接收数据。
我目前将应用模式设置为singleTask，并且由于其他问题而无法使用单一实例。
我的问题是即使在应用程序和服务从应用程序本身或从AdvancedTaskKiller或Forceclose关闭后经常退出，该服务将重新启动并初始化GPS。触摸通知将打开该应用程序。我再次停止跟踪，删除通知并关闭GPS关闭应用程序，几秒钟后服务重新启动。阻止它的唯一方法是关闭手机。
我该怎么做才能阻止这种情况发生。是否与操作方式有关？ START_NOT_STICKY或START_REDELIVER_INTENT？或者我需要使用stopSelf（）？
我的理解是，如果我使用bindService（）时服务没有运行，那么服务将被创建......所以我真的需要使用start / stopService吗？如果我希望服务在应用程序关闭后运行，我想我需要使用它。这就是我没有在onDestroy（）中取消绑定/停止服务的原因。这是对的吗？
我没有看到任何其他信息，所以我，我不确定在哪里看。
请帮忙！谢谢 帕特里克
