我正在尝试调用 startForegroundService(intent)，但我的应用程序在几秒钟后崩溃，但我可以在我的其他活动中调用 startForegroundService(intent) 它工作正常并且两个活动具有相同的代码。我无法弄清楚是什么导致了这个问题。我正在尝试在活动一中上传一些照片，它可以正常工作，但在此活动中，应用程序在几秒钟后崩溃，我单击按钮

为了避免您的应用程序崩溃，您必须在 onStartCommand 方法中调用 startForeground(notification)，以立即或在服务启动后立即显示通知。
<块引用>新的 Context.startForegroundService() 方法启动前台服务。即使应用程序在后台，系统也允许应用程序调用 Context.startForegroundService()。但是，应用必须在服务创建后的五秒内调用该服务的 startForeground() 方法。
