Can't drag in AndroidViewClient

Question

For some reason no matter what I do I can't issue a 'drag' command to my external android device using AndroidViewClient. Here is my code:

import sys
import os
import time

try:
    sys.path.append(os.path.join(os.environ['ANDROID_VIEW_CLIENT_HOME'], 'src'))
except:
    pass

from com.dtmilano.android.adb.adbclient import AdbClient
from com.dtmilano.android.viewclient import ViewClient, View

print 'Connecting to device...'
device, serialno = ViewClient.connectToDeviceOrExit()

 time.sleep(.5)
 AdbClient(serialno='.*').drag((500,1000),(500,100), 1, 10)

I have also tried

device.drag((500,1000),(500,100), 1, 10)

which also does not work. (btw, how does device.drag() differ from AdbClient.drag()?)

Also, I am NOT getting any errors from the above. Everything runs, and no errors are found. It just does not drag the screen.

Yet, touch events and keyboard events work:

device.touch(400,200, 'DOWN_AND_UP')

Note: my version of AndroidViewCLient is 7.0.2. My android device is Jellybean 4.1

EDIT: Ouput for my android device:

C:\Users\Me>adb shell input
usage: input ...
       input text <string>
       input keyevent <key code number or name>
       input tap <x> <y>
       input swipe <x1> <y1> <x2> <y2>

Answer 1

I found the problem. When AdbClient gets the API level (version) it's not converted to int so then the comparison in AdbClient.drag() fails because it's a string and the wrong command is sent to API 16. This:

__send(shell:input touchscreen swipe 500 400 100 400 1, checkok=True, reconnect=False)

instead of

__send(shell:input swipe 500 400 100 400, checkok=True, reconnect=False)

It will be fixed in AVC 7.0.4.
