It is clearly saying you didn't set the java and environment paths. To set up the environment follow Android environment setup Link

I used to have the same issue in WebStorm and found solution. The issue is due to WebStorm was written in Java and use v11.0.3 inside. So, do the following: 1. Open Webstorm --> Help --> Find action --> Switch boot JDK --> Change path to your v.1.8. In my case it's: "C:\Program Files\Java\jdk1.8.0_231" 2. add "JDK_HOME" in environment variables in your OS and set it's value: "C:\Program Files\Java\jdk1.8.0_231" Restart your Webstorm. That's it!

As others have said you need to update path variables, I want to add a few more parameters along these.
In the project, directory use this command to check Cordova compatibility.
$ ionic cordova requirements
This should show what you are missing.
Cordova needs Java JDK, Android SDK, Android target, Gradle.
- First install Java JDK as instructed here.
- Then you need to install Android SDK. If not installed, you can install it from here.
- You need to install Android Target, for this open SDK Manager in android studio and install android targets. Install a latest one as well as an old one.
- Install gradle. Use this link to install gradle.
Finally you need to sum up all these in path so command-line can recognise these.
Open .bashrc with $ ~/.bashrc and add these lines. (If you haven't done already).
export JAVA_HOME="/usr/lib/jvm/java-11-openjdk-amd64" # change location
export PATH=$JAVA_HOME/bin:$PATH
export GRADLE_HOME=/opt/gradle/gradle-5.2.1 # change location
export PATH=${GRADLE_HOME}/bin:${PATH}
export ANDROID_HOME=$HOME/Android/Sdk # change location
export PATH=$PATH:$ANDROID_HOME/cmdline-tools/latest/bin
export PATH=$PATH:$ANDROID_HOME/platform-tools
Change locations based on your installation directory.
NB: Make sure to add this line export PATH=$PATH:$ANDROID_HOME/cmdline-tools/latest/bin as old version of android studio's command-line has been deprecated and this is the updated command-line tool.
After this, reload the bash with $ sudo source ~/.bashrc
Then again check the requirements with ionic cordova requirements and this should display:
> cordova requirements
Requirements check results for android:
Java JDK: installed 1.8.0
Android SDK: installed true
Android target: installed android-29,android-28,android-26,android-23
Gradle: installed /opt/gradle/gradle-5.2.1/bin/gradle

I was stuck on this for a bit, I had JDK 8 (1.8) installed but it wasn't finding it - adding the second line
export PATH=$JAVA_HOME/bin:$PATH
in my .bash_profile then running source ~/.bash_profile Saved the day - here's by full .bash_profile for reference
export JAVA_HOME="/Library/Java/JavaVirtualMachines/jdk1.8.0_251.jdk/Contents/Home"
export PATH=$JAVA_HOME/bin:$PATH
export ANDROID_HOME=/Users/dylan/Library/Android/sdk
export ANDROID_SDK_ROOT=/Users/dylan/Library/Android/sdk
export ANDROID_AVD_HOME=/Users/dylan/.android/avd
export PATH="${PATH}:/$ANDROID_HOME/platform-tools:/$ANDROID_HOME/tools:/$ANDROID_HOME/tools/bin"
export ANDROID_HOME=~/Library/Android/sdk
export ANDROID_SDK_ROOT=~/Library/Android/sdk
export ANDROID_AVD_HOME=~/.android/avd
