如何调试Android项目 [英] How to debug Android project

问题描述

我是新来的Andr​​oid框架（使用Eclipse），我有一个关于调试的问题。最近我做了这个错误在一个活动：

I'm new to the Android framework (using Eclipse) and I have a question about debugging. Recently I did this error in an activity:

// The installation button
Button button = (Button) findViewById(R.id.preparationInstallButtonID);
button.setOnClickListener(this);

setContentView(R.layout.preparation);

即。我试过之前的布局已经变得添加一个onclick事件。这崩溃的程序，对不起，应用XXX意外停止。再次运行，具有调试模式，Eclipse将打开一个包含调试窗口。线程3;>（暂停）等（我敢肯定，你知道我说的是哪个窗口）

i.e. I tried to add an onclick-event prior the layout had been rendered. This crashed the program, "Sorry, the application xxx has stopped unexpectedly". Running it again, with debug-mode, Eclipse opens a Debug-window containing "Thread<3> (Suspended)" etc (I'm sure you know which window I'm talking about).

现在，我怎么能在这里提取出有用的数据？关于上述问题，我发现了如何通过反复试验的示数来修复它，但让我们说我不能做试验和错误，调试窗口如何能帮助我找到错误的根源？它说：例外的RuntimeException，但我没有看到任何指针作为凡在我code出现异常的。

Now, how am I able to extract useful data here? Regarding the problem above I found how to fix it by trial-and-erroring, but let's say I'm not able to do trial-and-error, how can the debug-window help me find the source of the error? It says "exception RuntimeException", but I don't see any pointers as of where in my code the exception occured.

推荐答案

使用的LogCat中这会给错误消息和你一切，在你为TestDevice /仿真器不胜枚举。

Use the LogCat this will give you the error messages and everything else that goes on in your testdevice/emulator.

窗口 - >显示视图 - >其他 - > LogCat中

Window -> Show View -> Other -> LogCat
