我的应用在后台不断崩溃。我确实有一些运行连接到Web服务的后台任务。我尝试过进行同步和异步调用。似乎没有任何帮助。令人抓狂的部分是崩溃日志没有给出任何确切原因导致崩溃的迹象。除了我没有正确地或在600秒内结束我的后台任务这一事实。回溯如何告诉我在我的应用程序中哪些线程导致崩溃？
我也不确定崩溃是因为当应用程序已经在后台然后我调用了webservice并且它永远不会返回（即使我现在正在使用同步）或者是因为我连接到应用程序进入后台时的webservice，这就是造成崩溃的原因。
我已阅读有关此内容的所有SO帖子。此外，它永远不会在应用程序在后台的模拟器上打破，也可以让我从网络上删除或重新打开它。请帮忙吗？
