android.graphics.Path.finalize() 10 秒后超时的根本原因是什么答案

【问题标题】：What is root cause for android.graphics.Path.finalize() timed out after 10 secondsandroid.graphics.Path.finalize() 10 秒后超时的根本原因是什么
【发布时间】：2017-04-01 20:04:56
【问题描述】：

致命异常：java.util.concurrent.TimeoutException： android.graphics.Path.finalize() 10 秒后超时在 android.graphics.Path.finalizer(Path.java) 在 android.graphics.Path.finalize(Path.java:748) 在 java.lang.Daemons$FinalizerDaemon.doFinalize(Daemons.java:202) 在 java.lang.Daemons$FinalizerDaemon.run(Daemons.java:185) 在 java.lang.Thread.run(Thread.java:818)

我在我的一个实时应用程序中遇到了这个错误，我尝试了所有可能的方法来解决这个问题，但仍然没有结果。如果有人能详细告诉我这个问题以及解决方法，那就太好了。提前致谢。

【问题讨论】：

这意味着对象的终结器花费了太长时间。要么它真的很大，要么线程暂停是出于某种原因——可能是死锁。
感谢您的快速回复。知道如何检测代码的哪一部分导致了这种情况吗？因为有了日志，我只能在堆栈跟踪上方看到，并且没有提到来自应用程序代码的来源。
它的起源是垃圾收集器。 Finalize 大致类似于一个析构函数，但没有承诺何时/是否会调用它。它在对象被内存收集之前调用。
您可能想查看stackoverflow.com/questions/24021609/…
好的。如何解决这个问题？

标签： android

【解决方案1】：

好的 - 这是我的答案：当垃圾收集器确定不再有对该对象的引用时，垃圾收集器对对象调用受保护的方法 finalize。子类覆盖 finalize 方法以释放系统资源或执行其他清理。就像在Google Developer Documentation 中一样

事实上，我在我的应用程序中遇到了同样的问题，它在一秒钟内绘制了数百条路径：见Visual Sounds Music Visualizer 而我的 Google Play Console 统计数据显示它仅适用于 Android 5.1

java.util.concurrent.TimeoutException:
