android 如何定位异常
android 怎么定位错误
初学安卓，看网上说的很笼统，有点看不懂，所以请教各位大侠，eclipse怎么去查找错误，今天拿一段代码进行调试，发现点击一个button后程序崩溃，只求调试方法和各位的思路，不吝赐教，同时希望大家多教教我怎么去操作，请说的详细些谢谢。

------解决思路----------------------
android.content.ActivityNotFoundException: Unable to find explicit activity class {com.pateo.as.settings/com.pateo.as.settings.activity.SettingActivity}; have you declared this activity in your AndroidManifest.xml?
看得懂什么意思不？跳转的activity没有在AndroidManifest里定义
------解决思路----------------------
你的activity有没有在AndroidManifest.xml里注册。
------解决思路----------------------
我也是Android新手，我看错误的时候就是找FATAL EXCEPTION、cause by之类的下一行。

在android配置清单把activity添进去就OK了。。建议以后新建activity的时候直接选择android下的activity，而不是用class然后自己去集成activity，这样很容易配置清单文件里面的信息忘记添加。

首先在logcat中找出红色的出错信息，之后红色的第一行一般会给出错误，看不懂英文的话在线翻译一下就ok了，之后找Cause By 开头的行，这一行会提示错误的类型，比如NullPointException等等，然后下一行一般就会指出你代码到底是那个类那一行出错了，直接双击就能跳到那一行代码，最后根据错误类型定位具体的错误原因。
如果第一行描述的不明确，也没有Cause By这一行，那你就找带有你项目包名类名的行，可以知道那一行出错，之后根据经验找错误原因
