cordova requirements issue , android target not installed

Question

I am trying to install Cordova on windows 7. I am following this tutorial : https://www.tutorialspoint.com/cordova/cordova_first_application.htm

while I run cordova requirements, it says android target is not intalled and set the ANDROID_HOME environment variable

I:\CordovaProject\hello>cordova requirements
Requirements check results for android:
Java JDK: installed 1.8.0
Android SDK: installed true
Android target: not installed
Android SDK not found. Make sure that it is installed. If it is not at the 
default location, set the ANDROID_HOME environment variable.
Gradle: installed
Error: Some of requirements check failed

I:\CordovaProject\hello>echo %ANDROID_HOME%
C:\Users\user\AppData\Local\Android\sdk

as you can see in the image 1, when I echo ANDROID_HOME it is set to proper location. I am not able to resolve this error. kindly help me with this

path has these : %ANDROID_HOME%\tools;%ANDROID_HOME%\platform-tools

I have downloaded android-25 in android studio

and project properties file has android target set to : android-25 both in I:\CordovaProject\hello\platforms\android\CordovaLib\project.properties
I:\CordovaProject\hello\platforms\android\project.properties

and when i run cordova build android i get following error

BUILD FAILED

Total time: 31.807 secs
Error: cmd: Command failed with exit code 1 Error output:

A problem occurred configuring root project 'android'.
 > Could not resolve all dependencies for configuration ':classpath'.

 intellij:uast:145.597.3)
