from com.android.monkeyrunner import MonkeyRunner as mr
from com.android.monkeyrunner import MonkeyDevice as md
from com.android.monkeyrunner import MonkeyImage as mi

device=mr.waitForConnection()
device.installPackage("../samples/android-14/ApiDemos/bin/ApiDemos.apk")
device.startActivity(component='com.example.android.apis/.ApiDemos')
result=device.takeSnapshot()
result.writeToFile('./snapshotbegin.png','png')

mr.sleep(5)

device.press('KEYCODE_DPAD_DOWN','DOWN_AND_UP')
device.press('KEYCODE_DPAD_DOWN','DOWN_AND_UP')
device.press('KEYCODE_DPAD_DOWN','DOWN_AND_UP')
device.press('KEYCODE_DPAD_DOWN','DOWN_AND_UP')
device.press('KEYCODE_DPAD_DOWN','DOWN_AND_UP')

result=device.takeSnapshot()
result.writeToFile('./snapshotend.png','png')

imageTrue=mr.loadImageFromFile('./snapshotbegin.png')
test=imageTrue.sameAs(result)
mr.alert('%s'%test)

将以上代码存放在test.py文件中，在../sdk/tools/目录下打开cmd,执行monkeyrunner test.py

前几天运行正常的程序，今天再执行却报错：

经查出错的地方是

result=device.takeSnapshot()
result.writeToFile('./snapshotbegin.png','png')

请教了几个同事，尚远同学指出关键的错误提示“Caused by:java.lang.IllegalArgumentException: Can't load standard profile: GRAY.pf”，搜了一下有人说是jdk有问题，重装一下就好了。另外参考了http://blog.youkuaiyun.com/half_human55/article/details/3988438 ，最终发现是由于我的jdk路径下../jre/lib/cmm下面是空的，从同事那里拷了整个文件夹过来就好了
