You can try to reinstall this platform by the way :

$ionic cordova platform rm android

And later :

$ionic cordova platform add android

Please keep me informed.

I faced javax.net.ssl.SSLHandshakeException before — in my case, it was due to an untrusted or expired certificate. I fixed it by updating the server’s SSL certificate and importing the correct CA cert into the Java keystore. Also, ensuring both client and server use the same TLS version helped resolve it.
