Native Application ERROR

I’ve followed the instructions for packaging native apps using native builder. Build process worked, created a .zip file with an apk in it inside the build folder. 1)Sometimes when i try to extract that zip file it says Unexpected end of Archive.and zip file does not contain anything  2) And  sometimes  if Zip is successfully extracted I’ve loaded the apk onto an Android phone.When I start the app I’m greeted with a White Screen  and App crashes. i am Using Mendix 8.12.1 and above .  Can anyone suggest what has gone wrong

Try debugging the native app to find what error occurs when you run the installed apk in mobile phone
