如何在未在ubuntu上安装Android Studio的情况下安装android SDK工具？

Question

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

It says that android script is deprecated, so you must use $ANDROID_HOME/tools/bin/sdkmanager --update for update all the installed packages, and $ANDROID_HOME/tools/bin/sdkmanager --list for see a list of installed, updates and available packages.
See more options at: https://developer.android.com/studio/command-line/sdkmanager.html or with $ANDROID_HOME/tools/bin/sdkmanager --help

$ANDROID_HOME refer to the location of your Android SDK. by example: export ANDROID_HOME=$HOME/android/sdk
