Android / Eclipse：帮助LogCat [英] Android/Eclipse: assistance with LogCat
问题描述
我试图从选项菜单开始一个活动。我尝试了许多不同的开始活动的方法，但是每次在startActivity时都会获得相同的结果。我已经定义了我的清单文件中的活动，我可以从一个按钮运行活动，而不是从onOptionsItemSelected。
我收到的错误是一个ActivityThread.performLaunchActivity （ActivityThread $ ActivityRecord，Intent）错误，所以我去搜索并找到以下问题：
Android：ActivityThread.performLaunchActivity错误
但是，我没有解决这个问题。 >
我想知道的是如何让我的logcat错误跟踪以上述链接中的asker显示的格式显示？我在logcat中找不到Caused By或者类似的东西，这将使我的调试变得更简单一些。所以如果有人能告诉我如何在logcat中找到这个信息，我将非常感激。
提前感谢Adam。
这是LogCat输出。这是关于我的手机正在做的很多信息，与实际在手机上运行的应用程序无关！

您是否显示了LogCat意味着

I am building an Android app at the moment, but it keeps crashing.
I am attempting to start an activity from an options menu. I have tried many different methods of starting the activity, but I get the same result each time at the startActivity. I have defined the activity in my Manifest file, and I can run the activity from a button, just not from onOptionsItemSelected.
The error I am receiving is an ActivityThread.performLaunchActivity(ActivityThread$ActivityRecord,Intent) error, so I went searching and found the following question:
Android: ActivityThread.performLaunchActivity error
However, I am not after a solution to this problem.
What I would like to know is how to get my logcat error trace to display in the format shown by the asker in the link above? I can't find a "Caused By" or anything similar in my logcat, which would make debugging a whole lot simpler for me. So if anyone can tell me how to find this information in the logcat, I would be very grateful.
Thanks in advance, Adam.
[EDIT] Here is the LogCat output. It's just lots of information about what my phone is doing, nothing to do with the app that's actually running on the phone!

Did you show the LogCat means,
Go to Window->Show View->Other->Android->LogCat. Here the whole android code debug/trace widgets are available you can simply click you can get it.
