Cordova-android v 9.0.0 build failed. Invalid Cordova android platform. API.js missing

Question

I have been working with Cordova-android@8.1.0 so far. Everything is in place and working fine. Due to API 29 support, I'm trying to upgrade Cordova-android platform to v9.0.0. But I'm facing a strange error.

Error:

Unable to load PlatformApi from platform. SyntaxError: Unexpected token ... Uncaught, unspecified "error" event. (The platform "android" does not appear to be a valid cordova platform. It is missing API.js. android not supported.)

Could not finish All tasks. See reason below

{ Error: Command failed: cordova platform add android@9.0.0 Uncaught, unspecified "error" event. (The platform "android" does not appear to be a valid cordova platform. It is missing API.js. android not supported.)

I have managed to fix this issue in my Cordova application. What happened to me was that I had an old Node.js version, so I could only use Android 7.0.0 with the command:

cordova platform add android@7.0.0

Otherwise, I had the same error as yours with the message: "The platform "android" does not appear to be a valid cordova platform. It is missing API.js. android not supported".

However, after upgrading my Node.js to the latest stable version (v14.5.1) with NVM ( https://github.com/nvm-sh/nvm ) and reinstalling the Android platform with the commands:

cordova platform rm android

cordova platform add android@9.0.0

My android application now could be built successfully with Cordova and the API 29.
