即使在我离开应用程序一段时间后，我的 logcat 中也会出现这些警告。（虽然没有杀，只是按回来离开它。）

这些数字很严重，而且很多。
我看到了一些关于这个问题的问题，但没有一个问题与我的相似，我不能接受“除非你没有 OOM 或冻结问题，否则忽略它”如果这可能导致，我不能等到它碰巧做一些事情它。
我只需要知道导致这种情况的原因以及如何防止这种情况发生。
我使用 Retrofit 来完成我的网络服务请求。还有一个 ThreadPoolExecutor 在等待请求完成时从缓存中获取/更新/删除数据。我认为这些都不会导致这种情况。
感谢您提供有关这种情况的任何想法或一般信息，因为我没有发现有关此“暂停所有线程”警告的任何具体信息。
