takeSnapshot ERROR #268

Closed uohoo closed 5 years ago

uohoo commented 5 years ago

When I try to use the functionality takeSnapshot, it seems that the socket is closed, I get the following error. I'm using BlueStacks emulator and is detecting the device correctly. When trying the other method, the alternative to USE_ADB_FRAMEBUFFER_METHOD, it shows the same behaviour.

Exception has occurred: RuntimeError
ERROR: b'FAIL' b'0006closed'
  File "C:\Program Files\Python37\Lib\site-packages\androidviewclient3\adb\adbclient.py", line 350, in __checkOk

You should use python 2.7.

Thank you for your quick respond. I tried with other emulators and physical devices using python3 and the code works properly. Any idea what this problem could be related with? Could be that sending the string 'framebuffer:' using python3 has a different behaviour that causes the error close? self.__send('framebuffer:', checkok=True, reconnect=False)

I was trying to find the problem and got this error message when executing the next line. I forced using the not FRAMEBUFFER method (BlueStacks uses the 25 sdk version which normally uses the FRAMEBUFFER method) but I guess that the same problem occurs when using FRAMEBUFFER. self.shell('/system/bin/screencap -p', False).replace(b'\r\n', b'\n')

I found the problem, BS was blocking connection because adb was disabled. I just had to enable Adb on BlueStacks options.
