java - Android 在 4.4.2 samsung 上不释放内存

Question

Android 新手，我开始掉头发了:

当我在三星上启动我的应用程序时，这是我每次启动 Activity 时得到的:

这意味着(我认为)内存未释放，因此当您长时间使用该应用程序时应用程序会崩溃。我不知道该对我的客户说什么......有什么帮助吗？谢谢

这是三星的一个错误。看here :

Yeah, i don't think we ever had a VMRuntime.pauseGC method. (and even if we did, VMRuntime and its methods are not public.)

并检查this回答。看起来这是三星的错误。
