The command “ionic cordova build android” is failing me.  
Here is the error I’m getting:

```auto
> cordova build android
Android Studio project detected
(node:19196) UnhandledPromiseRejectionWarning: Unhandled promise rejection (rejection id: 1): Error: Cannot find module '../cordova/platform_metadata'

(node:19196) [DEP0018] DeprecationWarning: Unhandled promise rejections are deprecated. In the future, promise rejections that are not handled will terminate the Node.js process with a non-zero exit code.

```

Here is my ionic info:

```auto

   ionic (Ionic CLI) : 4.1.1 (C:\Users\The Arctic AS\AppData\Roaming\npm\node_modules\ionic)

Your Cordova tooling seems to be out of date, which might be causing all kinds of problems.  
You can read about how to figure out the current Cordova versions and how to update CLI, platforms and plugins here: [How to update Cordova CLI, Platforms and Plugins · ionic.zone](https://ionic.zone/cordova/update)

Thanks for the quick reply.  
Yeah I wanted to keep an old version so that I knew everything would work well together, but somehow I’ve messed it up. Will try updating.

Hi @Sujan12 ,  
I’m actually not able to add Android again… as a plaform.  
Getting this issue:

```auto
t(node:20668) UnhandledPromiseRejectionWarning: Unhandled promise rejection (rejection id: 1): Error: Cannot find module '../cordova/platform_metadata'
(node:20668) [DEP0018] DeprecationWarning: Unhandled promise rejections are deprecated. In the future, promise rejections that are not handled will terminate the Node.js process with a non-zero exit code

```

Same as before.

Interesting.

Post the complete output of the command with `--verbose` added at the end.

I’ve removed the folder structures, don’t want to share it.

If it fails first, you have to remove it completely before trying again.

I had to downgrade my cordova to 7.1.0, and then it worked.
