2. Open terminal in that folder.
3. Run keytool -genkey -v -keystore HERE_YOUR_KEY_NAME-key.keystore -alias HERE_YOUR_APP_ALIAS_NAME -keyalg RSA -keysize 2048 -validity 10000. You will find a keystore file is generated in your app folder.
4. Run ionic cordova build android --prod --release --verbose

   After successfully executed this command you will get a message like this,

       D:\xyz\ion-cordova\platforms\android\app\build\outputs\apk\release\app-release-unsigned.apk

   It generate an unsigned apk that you never install in a phone so need to sign this apk.

1. Run jarsigner --verbose -sigalg SHA1withRSA -digestalg SHA1 -keystore HERE_YOUR_KEY_NAME-key.keystore "D:\xyz\ion-cordova\platforms\android\app\build\outputs\apk\release\app-release-unsigned.apk" HERE_YOUR_APP_ALIAS_NAME it will start signing this apk.

If you have already a keystore see the content inside it by

keytool -list -v -keystore my-release-key.keystore

then it will ask you to enter password.
