问题：
IntentService突然停止
申高峯
我有一个稍微令人困惑的问题，我认为由于一个愚蠢的疏忽，这将是一个容易解决的问题。
我的主要任务是上传图像和录音文件到我的服务器上的一个位置。我通过FTP这样做。
- 活动通过startService（intentName）调用服务
- onHandleIntent（）创建一个新线程
- 在新线程中，需要上传的文件被放入一个列表数组
- 在列表数组中循环。在这个循环中，将文件名传递给FTP服务器。如果添加成功，我会将此文件名添加到另一个包含已确认名称文件的ListArray中
- 循环完成后，我通过调用stopSelf（）停止服务。
- 我创建一个通知，通知用户服务已完成
我对第4步有问题。循环只上载我的两个文件，然后突然停止。上传第二个文件时，手机会进入睡眠模式。没有通知。
我试过以下方法
- 我最初使用AsyncWork，但这从来没有设法一次上传所有列出的文件。
- 使用StrictMode.
- 创建了第二个类，它是服务而不是IntentService。
- 尝试start Foreground（）-然而，这不是一个选项，因为这将杀死我的用户界面，我得到的应用程序不响应弹出窗口。
有人能提出一个前进的方向吗？这是我的密码
这是Main Activity.class中的代码
Intent service = new Intent(getApplicationContext(), UploadMedia.class);
service.putExtra("imageFileName", "/Folder/uploadtheseimagefiles.txt");
service.putExtra("audioFileName", "/Folder/uploadtheseaudiofiles.txt");
startService(service);
这是我的IntentService代码

新信息：根据我的测试用例，失败总是发生在第二个文件上。第一个图像大小约为900KB，第二个图像大小约为2MB。在调试中，我无法获得第二个文件的FTPUpload状态。但是调试器停止了第一个文件，我可以继续。
新信息：第2部分：可能相关。我正在使用asynctask将一些数据更新到服务器上的数据库中。一旦成功返回，它会整理所有需要上传的文件名。这些经过整理的数据就是我将意图传递给服务的内容。
也是另一个忏悔。我有这个确切的过程运行和工作在我的另一个应用程序。在后执行方法上，它调用服务将数据上传到FTP服务器。我比较了清单文件、服务和对服务的调用，一切似乎都是一样的。

您不需要调用stopSelf（），因为当队列中没有要服务的请求时，IntentService会自动停止。
添加更多的日志语句，以找出为什么它要在上传所有文件之前停止Self。

为什么要在onHandleIndent中创建新线程？这个方法已经从后台线程调用了，因此它不会妨碍你的UI呈现或其他什么。只需在onHandleIntent方法中直接运行逻辑即可。试试看

问题内容： 我使用JavaFX NumberBindings来计算某些值。最初，一切正常。但是，经过相当短的时间后，绑定将停止工作。我也没有收到例外。 我已经尝试了几种绑定以及高级和低级方法。即使计算本身（被覆盖时）也只是停止并且不再被调用。我还更新到了最新的JDK（1.8.0_05），并重新构建/重新启动了所有内容。 以下最小工作示例说明了该问题。它应该将System.out.println主窗

我的应用程序中正在运行IntentService。当用户按下“取消”按钮时，我想停止，但onHandleIntent会继续运行，即使在调用onDestroy（IntentService）时也是如此。 在执行过程中，我尝试了StSelfFe（），StutoIn（int）和StestService（意图），但不起作用。 我试图从碎片中停下来 提前感谢

我正在使用IntentService将图像上传到服务器。我的问题是我不知道如何/何时停止服务。当我在onHandleIntent（意图..）中调用stopself（）时将删除在IntentService队列中等待的所有意图。但我不想停止活动中的服务，因为我想完成上传过程，即使我的应用程序没有运行。

我的Visual Studio Code有问题。昨天我在打开VS Code的情况下关闭了我的电脑，当我再次打开电脑时，所有VS Code扩展都停止了工作。我在项目中使用React和Types cript，我真的需要这些扩展。我的eslint和漂亮的配置也停止了工作。如果有人有同样的问题，请回答。
