I found the APK generated by the voltbuilder can be install as upgrade (without uninstall the previous version of app and keep all existing sqlite data). Is there any way to download the APK file within the android app and then it will start to install automatically?
Good question. You’d have to know the url of the APK file. Try opening it like this:
location.href = url
Let us know if it works!
It work on browser, but it is not working within the native app APK.
