Android的工作室静态= libcore.io.Posix ENOENT例外 [英] Android Studio static = libcore.io.Posix ENOENT exception

问题描述

我想在模拟器上运行我的应用程序。它用于工作，但现在它不正确加载。调试的错误，我得到的是：

I am trying to run my app on a emulator. It used to work but now it does not load properly. The debug error I get is:

static = libcore.io.Posix
  Exception = {android.system.ErrnoException@3564}

当我右键单击例外线和复制值获取：

When I right click on the Exception line and Copy Value I get:

  android.system.ErrnoException: stat failed: ENOENT (No such file or directory)

我的应用程序没有任何文件IO程序性所以异常必须涉及到一些系统要求。

My app does not have any file io programed so the exception must relate to something the system requires.

回望LogCat中我得到ENOENT匹配，几行之前是：

Looking back in the LogCat I get a match for ENOENT, several lines before are:

com.google.process.location W/art? Suspending all threads took: 7.795ms

com.google.process.location E/copresGcore? Couldn't load settings: /data/data/com.google.android.gms/files/copresence_settings: open failed: ENOENT (No such file or directory)

我看不出有什么文件，它不能读/写。我没有IO编程任何文件，但我使用的sqlite3的，也许到系统无法找到数据库文件。

I cannot see what file it cannot read/write to. I do not have any file IO programmed but I am using sqlite3, maybe to system cannot find the database file.

要从这个错误了一段时间，我创建Android Studio中的新项目得到一定缓解。关闭AS和复制我的源文件复制到新AS项目中。然后，当我跑新项目，错误已经走了。这几个小时的编程和编辑后回来。

To get some relief from this error for a while I created a new project in Android Studio. Shut down AS and copied my source files into the new AS project. Then when I ran the new project, the error had gone. It came back after several hours of programing and editing.

我已经看过了互联网2天了都没有成功的解决方案。任何帮助将是AP preciated。

I have looked for solutions on the internet for 2 days now without success. Any help would be appreciated.

进一步了解详细：结果
如果我运行（不调试）在模拟器上或它的工作设备的应用程序。结果
如果我上运行模拟器或它与同libcore异常崩溃的设备/调试。结果
部分结论：它是与调试

Further details:
If I run (not debug) the app on the emulator or the device it works.
If I run/debug on the emulator or the device it crashes with the same libcore exception.
Part conclusion: it is something to do with debugging.

我想我曾经碰到过一个解决方法：

I thought I had come across a workaround:

1. 我关闭现有的AVD


2. 我从AS AVD管理运行AVD


3. 我重新安装应用程序：ADB安装-r C：\\用户\\ APP-debug.apk


4. 我跑从AS应用推调试按钮

这一次得手那么libcore出现的错误。这种解决方法并不好，即使它的工作，作为编辑运行/周期过长。

This worked once then the libcore error appeared. This workaround is not good, even if it worked, as the edit run/cycle is too long.

我觉得唯一的办法就是断点的谷歌源，以确定它是什么的除外。我花了很多时间来搜索互联网，以找出如何做到这一点没有成功。如果任何人都可以点我的相关文章我将不胜感激。

I think the only way is to breakpoint the Google source to determine what it is excepting on. I spent much time searching the internet to find out how to do this without success. If anybody can point me to relevant articles I would be grateful.

推荐答案

我提出了Android开源项目的问题126510.的意见通过jcossi ... @ gmail.com给出了答案。我已经转向了Java异常断点以检查任何异常。当我重新启动该项目这导致的问题。我看来，应用程序可以使用异常处理不只是错误。所以，如果你使用任何异常一定要记得再次尽快禁用它。

I raised Android Open Source Project issue 126510. The comments by [e-mail] gave the answer. I had turned on "Java Exception Breakpoints" with "Any exception" checked. This caused the problem when I restarted the project. I seems that applications may use exception handling for not just errors. So if you use "Any exception" be sure to remember to disable it again ASAP.
