# Ensure on each release you have updated android/app/build.gradle (and possibly android/app/src/main/AndroidManifest.xml ??):
#        versionCode 1
#        versionName "1.0"
# versionCode is an integer which Google Playstore recognises and does not allow to upload another APK having the same value. Just think of this as build number. 
# versionName is the version number of your application and visible in Google Play Store. Can use server format.
# See https://saumya.github.io/ray/articles/72/
