You may get more insight by running the Cordova command above directly.
[ERROR] An error occurred while running cordova build android (exit code 1):
Error: Failed to find 'ANDROID_HOME' environment variable. Try setting
setting it manually.
Failed to find 'android' command in your 'PATH'. Try update your 'PATH'
to include path to valid SDK directory.
What is the error all about and how can i solve it.
Thank you 
It seems as though you are missing the android SDK which is required to build for android.
The simplest solution is to just install android studio and that will solve the issue by installing the SDK.
https://developer.android.com/studio/index.html
For more information see: https://ionicframework.com/docs/intro/deploying/
Good, i will try your solution and i will come back with the result
I am back,
i try your solution which is installing the latest version of ''Android Studio" that comes with the Android SDK.
and then i try again to generate the apk for the ionic application and the console returns me this error:

Sum of these errors are helpful enough if you break them down
This is because you have not accepted the licence agreements, you can choose to open Android Studio SDK Manager and accept them or alternatively you can try this Stackoverflow solution https://stackoverflow.com/questions/40383323/cant-accept-license-agreement-android-sdk-platform-24/40383457#40383457
I try your solution for creating the file of licences manually but this time it output me this error:
