Monkeyrunner截图报错

Codinglangzi · 发表于 2019-7-2 11:32:17

刚学习了一天，简单copy了个截图的代码，貌似只成功了一次，之后全部都报一样的错误。
from com.android.monkeyrunner import MonkeyRunner, MonkeyDevice, MonkeyImage
device = MonkeyRunner.waitForConnection()
#device.press('KEYCODE_HOME',MonkeyDevice.DOWN_AND_UP)
pict = device.takeSnapshot()
MonkeyRunner.sleep(2)
pict.writeToFile(r'C:\WuZhongjian\Doc\pic2.png','png')

下面是命令行窗口报得错误：
