adb.exe continues to run after program exit

[Datamined]

Hello.

After running any python script using uiautomator there are still exist two processes 'adb.exe'. It looks like Adb() object runs adb-command through Popen that waits for .join() that never happen. It also blocks any commands input to cmd in very strange way: after writing any command and pressing ENTER nothing happens. Pressing ENTER second time returns to %your_dir%>

Here is a sample code to demonstrate:

# -*- coding: utf-8 -*-

from uiautomator import AutomatorDevice as Device

import json
import xmltodict

def getEmuInfo():
    
    d = Device('emulator-5556', adb_server_host='127.0.0.1', adb_server_port=5037)
    
    content = d.dump()
    content = xmltodict.parse(content)
    
    print(json.dumps(content, indent = 4))
    
    return

getEmuInfo()
print "program finished"

Here is the output:

The only possible workaround is to kill adb.exe process.

I have ran into this issue too. The symptom I ran into was that I could not launch uiautomatorviewer after running my tests. I was doing adb kill-server and then adb start-server to recover per this post: https://stackoverflow.com/questions/40214342/error-obtaining-ui-hierarchy-error-while-obtaining-ui-hierarchy-xml-file-com-an

Though I can confirm that adb.exe is still running, and killing it is what indeed fixes the issue.

The problem is uiautomator is conflict with uiautomatorviewer

Correct. My workaround is to call ‘device.server.stop’ upon test completion, which appears to shutdown adb connection
