title: Android Update app without disturbing local Sqlite DB
body: <p>I have an App on Playstore. The app is named Credit Flow.It is used to track income and expenses of an individual. 
  I use local Sqlite Db to save all the transactions(they are not saved on any server). 
  I am new to pushing apk updates. My question here is that if I upload a new Apk on  playstore will it erase the existing user's Local Db?</p>
  
  <p>If so how can I prevent that?  </p>
