Ionic run android does not run app on device

Question

I am new to ionic and I am trying to run a sample app of ionic on my phone ( Samsung Galaxy s4 ) and I am unable to do so. I already have "USB Debugging" on in Developer Options.

As seen above even though my phone is connected it runs on emulator. The app works on emulator without an issue

When I do

$ionic run android

In logs says:

No target specified and deploying to emulator

The emulator comes up and has no issues in running the app.

Then I tried

$adb devices -l

Its shows my device XXX listed there

Now I try running

$ionic run --devices

Its says : Unknown platform : XXX

I tried

$ionic run -d 'XXX'

It throws error

CordovaError: Unknown platform : XXX at cli .....

I even tried by defining a run config file specifying the target, however the results are similar. It throws error at q.js throw e;

Target 'XXX' not found, unable to run project.

Can somebody please advise what step I have missed?

First make sure you've installed cordova, latest at the time of writing is 8.0.0
$ cordova -v

Once it is installed connect your device enable debugging in developer option, if it's first time it might ask approve RSA key accept/ok it.
then run command
$ ionic cordova run android --device

make sure you made path setting with respect to android studio in Environment Variables.

with below command you can clean cache
$ npm cache clean --f
