cordova.cmd build android

Hi, I too faced this issue today and solved.

For me,
executing below commands one by one from terminal inside the project directory worked out.

export ANDROID_SDK_ROOT=$HOME/Android/Sdk
export ANDROID_HOME=$HOME/Android/Sdk
export PATH=$PATH:$ANDROID_SDK_ROOT/tools/bin
export PATH=$PATH:$ANDROID_SDK_ROOT/platform-tools
export PATH=$PATH:$ANDROID_SDK_ROOT/emulator
export PATH=$PATH:$HOME/Documents/gradle-5.6.1/bin

And for your other errors regarding angular package errors,remove their version from package.json,uninstall and re-install them.

change below in package.json:
“@angular-devkit/build-angular”: “^0.801.2”

npm uninstall
npm i

Do same for other packages.
