这个答案描述检索的堆栈跟踪的过程。已经有堆栈跟踪？阅读上的堆栈跟踪在<一href="http://stackoverflow.com/questions/3988788/what-is-a-stack-trace-and-how-can-i-use-it-to-debug-my-application-errors">What是一个堆栈跟踪，以及如何使用它来调试应用程序错误？的
您的应用程序退出，因为一个未被捕获的RuntimeException 被抛出。
最常见的是 NullPointerException异常。
Your application quit because an uncaught RuntimeException was thrown.
The most common of these is the NullPointerException.
每一个Android应用程序崩溃（或与此有关的任何Java应用程序），一个堆栈跟踪被写入到控制台（在这种情况下，logcat中）的时间。该堆栈跟踪包含解决你的问题的重要信息。
Every time an Android application crashes (or any Java application for that matter), a Stack trace is written to the console (in this case, logcat). This stack trace contains vital information for solving your problem.
在窗口底部栏，点击安卓按钮。或者，您可以preSS <大骨节病> ALT + <大骨节病> 6 。请确保您的模拟器或设备中的设备面板被选中。其次，尽量找堆栈跟踪，其中显示为红色。可能有很多东西登录到logcat的，所以你可能需要滚动了一下。一个简单的方法来找到堆栈跟踪是再次明确logcat的（使用右侧回收站），并让应用程序崩溃。
In the bottom bar of the window, click on the Android button. Alternatively, you can press alt+6. Make sure your emulator or device is selected in the Devices panel. Next, try to find the stack trace, which is shown in red. There may be a lot of stuff logged into logcat, so you may need to scroll a bit. An easy way to find the stack trace is to clear the logcat (using the recycle bin on the right), and let the app crash again.
在右上角，点击 DDMS 按钮。如果它不存在，则可能需要先使用打开透视按钮，添加到左侧的的Java 按钮。你会发现在底部的logcat的窗格中。首先，确保你的设备在左上设备小组选出。其次，尽量找堆栈跟踪，其中显示为红色。此外，可能有很多东西登录到logcat的，所以你可能需要滚动了一下。一个简单的方法在这里找到的堆栈跟踪是清除的logcat（使用清除日志在右侧顶部的按钮），并让应用程序崩溃了。你也应该点击您的应用程序的包名，如果它不被选中。这将筛选出的，只有你的应用程序所做的日志信息。
In the top right corner, click the DDMS button. If it is not there, you might need to add it first using the Open Perspective button to the left of the Java button. You will find the logcat pane at the bottom. First, make sure your device is selected in the topleft devices panel. Next, try to find the stack trace, which is shown in red. Again, there may be a lot of stuff logged into logcat, so you may need to scroll a bit. An easy way to find the stack trace here is to clear the logcat (using the clear log button on the top right), and let the app crash again. You should also click on the package name of your app, if it is not already selected. This will filter out only the log message made by your app.
耶！你中途解决您的问题。
你只需要找出究竟是什么使你的应用程序崩溃，通过分析堆栈跟踪。
Yay! You're halfway to solving your problem.
You only need to find out what exactly made your application crash, by analyzing the stack trace.

如果你发现你的异常和在何地发生，但仍无法弄清楚如何解决它，不要犹豫，问一个关于计算器的问题行。
If you've found your Exception and the line where it occurred, and still cannot figure out how to fix it, don't hesitate to ask a question on StackOverflow.
尽量保持尽可能简明：张贴堆栈跟踪和相关的code（如几行至该扔了异常的行）。
Try to be as concise as possible: post the stack trace, and the relevant code (e.g. a few lines up to the line which threw the Exception).
