Following your recommendation, I was able to solve the SDK issues.
But now I'm getting an error at the second last step to publish
jarsigner -verbose -sigalg SHA1withRSA -digestalg SHA1 -keystore gurubudy.keystore android-release-unsigned.apk wplms
the issue is there is no "android-release-unsigned.apk" file in the apk folder. I also couldn't find it in the whole ionic project folder
