Something wrong with ViewClient.connectToDeviceOrExit()

Question

I'm recently started to use python with mobile app automation, as i decided to use python, the main instruments that I've found were monkeyrunner and androidviewclient.

But there is the first issue with which i dont know what to do:

package = 'com.mypackage.android'
activity = '.launchActivity'
component = package + "/" + activity

device, serialno = ViewClient.connectToDeviceOrExit()
device.startActivity(component=component)


time.sleep(3)

vc = ViewClient(device, serialno)
vc.dump()

showMenu = vc.findViewById("id/no_id/8")
showMenu.touch()

as i'm running it in windows cmd - monkeyrunner mypath\test-case1.py i receive an exception:

131213 18:42:32.555:S [MainThread] [com.android.monkeyrunner.MonkeyRunnerOptions] Script terminated due to an exception

NotImplementedError: alarm not implemented on this platform

am I doing something wrong? Please help.

Thank you a lot!

Answer 1

This is how setAlarm looks like

@staticmethod
def setAlarm(timeout):
    osName = platform.system()
    if osName.startswith('Windows'): # alarm is not implemented in Windows
        return
    signal.alarm(timeout)

so, it tries to identify that is Windows and then not invoking signal.alarm() which is not implemented, but for some reason it fails in your case. Try to print the result of osName to see what went wrong.

UPDATE

Now I see, you are using monkeyrunner as the interpreter but AndroidViewClient >= 4.0.0 is 100% pure python, so you should run your scripts using a python 2.x interpreter.
