how to access and modify my existing database made by DB browser for SQLite in unity after build

Hello everyone, I am trynig to find a way to access and modify what ever i want (insert new values,delete from TABLE ,assign new VALUES,search in table... )in my local database that i have created with DB browser for SQLite in unity 3D v4.5 pro, after building it on windows or specially most important point on android. I have tested to access my database on unity editor and it works but when i build it he can't find the connexion to it (non on windows,non on Android).Please can any body help me if it's possible of course to get a good result. Please,Am so in need to help. :'(

Ps: My database must be serverless(local) and can build it on android that's why i've chosen SQlite.
