Question

I am trying to generate.apk file for my angular application.

To generate apk used -
cordova build android

I have also set user variables and system variables
ANDROID_HOME = C:\Users\user\AppData\Local\Android\Sdk
JAVA_HOME = C:\Program Files\Java\jdk1.8.0_271
PATH =...;C:\Program Files\Java\jdk1.8.0_271\bin;
C:\Users\user\AppData\Local\Android\Sdk\tools;
C:\Users\user\AppData\Local\Android\Sdk\platform-tools

echo %JAVA_HOME% is printing => C:\Program Files\Java\jdk1.8.0_271
java -version => java version "1.8.0_271"
Java(TM) SE Runtime Environment (build 1.8.0_271-b09)
Java HotSpot(TM) 64-Bit Server VM (build 25.271-b09, mixed mode)
gradle -v => Gradle 5.6.3
cordova -v => 9.0.0 (cordova-lib@9.0.1)
cordova platform version android => Installed platforms:
android 9.0.0

Android Studio installed => 4.0.0

my error is

ANDROID_SDK_ROOT=undefined (recommended setting)
ANDROID_HOME=C:\Users\user\AppData\Local\Android\Sdk (DEPRECATED)
Using Android SDK: C:\Users\user\AppData\Local\Android\Sdk
