after several month when i tried to open Android SDK manager i realized it's not loading any of packages that i didn't install or have updates and just showing already installed packages (like there is not any internet connection), but there isn't any connection error shows in log like image bellow
i checked Official Add-on site list and it's Empty
i checked sdkmanager.bat file in tools\bin path and i got this error that can't parse xml file
note that i can access the xml file manually when enter it's path in browser.
is there anything i can do to fix this?
UPDATE
I figured out the reason of this problem and i added an answer for it.
