Android致命信号11 (SIGSEGV)在0x636f7d89(代码=1)。怎样才能找到它呢?

我一直在阅读其他关于在Android应用程序中获得SIGSEGV的原因的帖子。我计划在我的应用程序中寻找可能与画布使用相关的空指针，但我的SIGSEGV每次都会抛出不同的内存地址。加上code=1和code=2。如果内存地址是0x00000000，我有一个线索，它是一个空指针。

我得到的最后一个是代码=2:

A/libc(4969): Fatal signal 11 (SIGSEGV) at 0x42a637d9 (code=2)

有什么建议吗?

I have a suspect, but I'm not keen on experimenting with it yet. My app uses the OSMDroid API for offline mapping. The OverlayItem class represents markers/nodes on the map. I have a Service that collects data via the network to populate the OverlayItem which are then displayed on the map. In an effort to simplify my design, I extended OverlayItem into my own NodeOverlayItem class, which includes some addition attributes I use in the UI Activity and in the Service. This gave me a single point of Item information for the UI and Service. I used Intents to broadcast to the Activity to refresh the UI map when something changed. The Activity binds to the Service and there's a Service method to get the list of NodeOverlayItem's. I think it might be the OSMDroid API's use of OverlayItem, and my Service updating node information at the same time. (a concurrency issue)

As I write this I think that's really the problem. The headache isn't splitting out the Node and OverlayItem from NodeOverlayItem, it's that the Activity will need some data from the Node, that the Service holds. Plus when the Activity is created (onResume, etc...) the OverlayItem objects will need to be re-created from the Node data that the Service has been maintaining while the Activity was away. e.g. You start the app, the Service collects data, the UI displays it, you go to Home, then back to the app, the Activity will need to pull and re-create the OverlayItem's from the latest Service node data.

我知道这不是一个很好的问题。就好像我所有的SO问题都是小众或模糊的。如果有人对如何解释这些SIGSEGV错误有建议，将不胜感激!

更新 下面是在调试会话期间捕获的最新崩溃。我有3个这样的设备用于测试，当我在开发和测试时，它们都不会可靠地崩溃。我额外添加了一些内容，以便能够注意到GC日志记录。您可以看到，这个问题可能与内存耗尽无关。

试着在你的清单中禁用Android硬件加速。

android:hardwareAccelerated="false"

我也得到了这个错误很多次，我解决了它。 在本机进行内存管理时将会遇到此错误。

Your application is accessing memory outside of its address space. This is most likely an invalid pointer access. SIGSEGV = segmentation fault in native code. Since it is not occurring in Java code you won't see a stack trace with details. However, you may still see some stack trace information in the logcat if you look around a bit after the application process crashes. It will not tell you the line number within the file, but will tell you which object files and addresses were in use in the call chain. From there you can often figure out which area of the code is problematic. You can also setup a gdb native connection to the target process and catch it in the debugger.

对我来说，这个问题是由于两个活动之间的糟糕演员。 我最近把这个方法从Activity1移到了另一个2。 这样做时，重构会保留这个显式强制转换，就像以前一样。 所以与其这样做

((Activity1) mainActivity).hideDialog();

我应该做的

((Activity2) mainActivity).hideDialog();

注意:但是这个错误在android 8.0上没有发生，我还不确定为什么。

***希望能有所帮助。

我在Android Studio中尝试“应用更改并重新启动活动”时遇到了这个问题，从那时起应用程序就无法启动。原因是我尝试了这个可能在片段内，但我不得不重新启动我的手机，我用来测试我的应用程序，然后问题就消失了。

我在使用Flutter 2.8.1时遇到了这个问题。

我搜索了很多，但没有什么帮助(禁用我正在使用的外部包，调试，使缓存无效，颤振清理，重新启动模拟器，等等)。

事实证明，这与我在CustomPainter类中所做的工作有关。即使画一个简单的矩形也可能导致这种崩溃。

我切换到beta通道(Flutter 2.9.0-0.1.pre)，问题完全消失了。

我有这个分割错误错误，因为内存问题。 我的结构体有很多变量和数组，数组的大小是1024。

将大小减小到512，错误就消失了。

附注:这是一种变通方法，而不是解决方案。 有必要找到结构的大小和动态内存分配 是更好的选择。
