Now the key file is successfully generated in the path in which u have ran the commands.
Place the key file generated in the path where apk file is generated.
(C:\<ur cordova prj>\platforms\android\build\outputs\apk)
Now run the command to generate release build
jarsigner -tsa http://timestamp.digicert.com -verbose -sigalg SHA1withRSA -digestalg SHA1 -keystore ultimateCreations-crazyColors.keystore android-release-unsigned.apk ultimateCreationsCrazyColors
Finally, we need to run the zip align tool to optimize the APK:
zipalign -v 4 android-release-unsigned.apk CrazyColors.apk
Enjoy...................!
