EasyMonkeyDevice not found error while running monkeyrunner python script

Question

I want to run monkeyrunner python script.

from com.android.monkeyrunner import MonkeyRunner, MonkeyDevice
from com.android.monkeyrunner.easy import EasyMonkeyDevice
from com.android.monkeyrunner.easy import By
from modjy.modjy_params import INTEGER


# Connects to the current device, returning a MonkeyDevice object
device = MonkeyRunner.waitForConnection()

easyDevice = EasyMonkeyDevice(device)
MonkeyRunner.sleep(2)
easyDevice.touch(By.id('id/btnSignUp'),MonkeyDevice.DOWN_AND_UP)

Below is the command I am using to run script

c:\path_to_and_sdk_tool> monkeyrunner test.py 

But I am getting error when I get "EasyMonkeyDevice" Object.

File "C:\python\test.py", line 19, in <module>
            easyDevice = EasyMonkeyDevice(device)
        java.lang.RuntimeException: Could not connect to the view server

Please share some links from where i can get EasyMonkeyDevice import

Answer 1

You have to implement ViewServer to use EasyMonkeyDevice : https://github.com/romainguy/ViewServer because easyMonkey uses Hierarchy Viewer.

In your activities :

Enable ViewServer for hierarchy viewer like this :

public class MyActivity extends Activity {

     public void onCreate(Bundle savedInstanceState) {
         super.onCreate(savedInstanceState);
         ViewServer.get(this).addWindow(this);
     }

     public void onDestroy() {
        super.onDestroy();
        ViewServer.get(this).removeWindow(this);
     }

     public void onResume() {
        super.onResume();
        ViewServer.get(this).setFocusedWindow(this);
     }
}

Answer 2

Alternatively, you can use AndroidViewClient and you won't be forced to implement a ViewServer in your application.

This will do the same as your previous script:

#! /usr/bin/env python

from com.dtmilano.android.viewclient import ViewClient
ViewClient(*ViewClient.connectToDeviceOrExit()).findViewByIdOrRaise('id/btnSignUp').touch()

You can also generate this kind of script or unit tests just by running culebra -UG (in AndroidViewClient tools) and click on the UI representation of the device to automatically generate the touch() invocations.
