Could you give more detail on the context of the error? it is hard to understand what is going on with the error log.

Hi Brian,

Thanks for you reply, attachment is the error screenshot of downloading Android SDK, I can download Android platform-tool standalone from google, but failed to download via katalon, I 've tried to use adb from other folder location to get connected device, and it’s OK, could you guide me how to solve this issue?

Thanks in advanced

[ray.xu]

Sorry for my confusion, I should provide more details for this issue.

[Brian_Ducson]

Hi,

I think the info is enough now. Trying to find the root cause.

Hi Ray,
I’ve tried downloading Android SDK via Katalon tool by following your steps strictly and the downloading process is completed successfully.
Does your network has any proxy? If yes, please config proxy for Katalon tool (Window -> Katalon Studio Preferences -> Katalon -> Poxy) then try to download Android SKD again.

Hi Loan,
I used shadowsocks as a proxy server and set it up from Katalon Preferences, but I still get an error, I tried other proxy, and problem is solved, thanks you for your guidance:blush:
