npm install --save @ionic-native/diagnostic

and after that added the android platform  as below :

ionic platform add android@latest

Now I am trying to build it with ionic build android console but it gives me below error :

Error: Could not find an installed version of Gradle either in Android Studio,
or on your system to install the gradle wrapper. Please include gradle 
in your path, or install Android Studio

How to fix above error?

Answer 1

I know such errors are really hard to fix for beginners.

If you are windows user then you can follow below procedure to fix it.

At the beginning you need to download the Gradle binary.

After downloading just extract your zip file to 'C:\Gradle' or your preferred folder

Then you need to open the edit environment variable dialog from your start menu > Search

Now click on 'New' under your system variables and then add as below

The Variable Name GRADLE_HOME and Variable Value C:\Gradle\gradle-4.0.1

After that you can choose PATH variable from your system variable list

Then you need to append your gradle path to variable value as follows C:\Gradle\gradle-4.0.1\bin

Now press the win Key+R and type cmd then enter > in the command terminal type gradle -v

If you done the setup correctly then you will see your gradle installation details.
