I was trying to install Android SDK with the help of the SDK command line tools downloaded from the link https://dl.google.com/android/repository/sdk-tools-linux-3859397.zip on my Linux Ubuntu 16.04 PC. i run the command following command for installation
./android update sdk
sudo ./android update sdk
but getting the this error
how to solve this error ?or suggest me a proper way to install build tools.
FYI
and also i read that ~/.android should contain androidtool.cfg file which has below data in it.
http.proxyPort=proper_port
http.proxyHost=Proper_proxy_ip
sdkman.show.update.only=true
sdkman.ask.adb.restart=false
sdkman.force.http=true
