[ERROR] An error occurred while running cordova build android (exit code 1).

Can we see some ionic info details?
Make sure to use latest Cordova version along with compatible local Android platform package.

If I get mentioned error, after checking everything is good, I remove Android platform and plugin folder and then re-add Android platform back. It could be due to miss-matches in installed plugins.

try to clean build your project by gradlew clean.

Try the following steps -

Add cordova-android-support-gradle-release plugin with ionic cordova plugin add cordova-android-support-gradle-release
remove android platform with ionic cordova platform rm android
then build again
