Android>>AndEngine：这个LogCAT形式的错误是什么意思？

发布于 2024-11-17 10:06:35 字数 6179 浏览 2 评论 0原文

我怀疑各种数组列表访问存在线程或问题。好吧，我不再收到“简单”的并发异常，只有以下形式的相同错误消息。

我在某处读到这可能是由于 Dalvik VM 本身崩溃造成的。

我还注意到 /libandenginephysicalsbox2dextension.so 的出现。

在测试中，我尝试删除在 AndEngine 的更新线程上执行的代码，并且错误更容易、更频繁地弹出。

我即将隔离一个测试用例，但它的复制模式仍然让我困惑。

对此输出的任何帮助甚至普通分析将不胜感激，因为这是我以前见过但从未学过的模式。

谢谢大家！

I suspect a threading or issue with various arraylist access. Well, I no longer get 'easy' concurrency exceptions, only the same error message in the following form.

I've read somewhere that this may be due to Dalvik VM itself crashing.

I also note /libandenginephysicsbox2dextension.so appearing.

In tests, I've tried removing code executed on AndEngine's update thread, and the error pops up easier and more frequently.

I am getting close to isolating a test case, but the pattern of its reproduction still eludes me.

Any help or even mundane analysis of this output would be appreciated, as it is a pattern I've seen before, but have never learned.

Thanks all!

通常这种错误意味着您正在干扰“错误”线程上的本机物理库，该线程通常是 UI 线程，（默认情况下）TouchEvents 和 KeyEvents 在其中运行。

Usually this kind of error means that you are interfering with the native physics library on the "wrong" Thread, which usually is the UI-Thread, where (by default) TouchEvents and KeyEvents run on.

该错误基本上意味着 AndEngine 使用的 box2d 实现在某些时候导致分段错误： NULL 指针，超出范围写入数组或访问某些未正确初始化的变量。如果您的游戏有本机代码，我会使用 valgrind 或其他一些静态代码分析工具对其进行检查，以查看您在某处使用某些变量时是否犯了明显的错误。或者，您可能想尝试单步执行您编写的调用 box2d 的代码：我个人没有太多调试本机代码的经验，但我知道这是可能的。

The error basically means that the box2d implementation used by AndEngine is at some point causing a segmentation fault: either a NULL pointer, writing to an array out of bounds or accessing some variable that is not properly initialized. If your game has native code I'd go over it with valgrind or some other static code analysis tool to see if you are making obvious mistakes in the use of some variable somewhere. Alternatively you might want to try single stepping through the code you've written that is calling box2d: I've personally not had much experience debugging native code, but I know its possible.
