Android ANR错误有讲解

addison_lin

Android ANR这个错误大家并不陌生，但是从Android 2.2开始出错的ANR信息会自动上传给Google进行系统分析改进，当然了你的应用ANR错误其实保存在一个文件中，在/data/anr /traces.txt文件中，如果你的Android设备没有Root越狱过，可以将你的软件装在模拟器上分析，模拟器可以直接使用Eclipse中的 DDMS里的File Explorer来打开，如下图:

        虽然traces.txt是一个文本文件，不过使用windows上的记事本打开可能无法正常处理linux的换行符，这里Android建议你使用 ultra edit查看，当然了使用Windows自带的写字板也是不错的。下面一起来分析下错误吧，第一行为出错的时间，第二行都会写上发生ANR的 package Name，下文是com.android.systemui这个包，里面的部分线程出了问题，通过下面的的xxx方法以及对应的java文件，后面的数字 为xxx.java文件的第几行，是不是很方便呢?
