查看stdout 和stderr
在默认状态下，Android系统有stdout 和 stderr (System.out和System.err )输出到/dev/null ，
在运行Dalvik VM的进程中，有一个系统可以备份日志文件。在这种情况下，系统会用stdout 和stderr 和优先级 I.来记录日志信息

通过这种方法指定输出的路径，停止运行的模拟器/设备，然后通过用setprop 命令远程输入日志

$ adb shell stop
$ adb shell setprop log.redirect-stdio true
$ adb shell start系统直到你关闭模拟器/设备前设置会一直保留，可以通过添加/data/local.prop 可以使用模拟器/设备上的默认设置

UI/软件 试验程序 Monkey
当Monkey程序在模拟器或设备运行的时候，如果用户出发了比如点击，触摸，手势或一些系统级别的事件的时候，
它就会产生随机脉冲，所以可以用Monkey用随机重复的方法去负荷测试你开发的软件.
最简单的方法就是用用下面的命令来使用Monkey，这个命令将会启动你的软件并且触发500个事件.
