Browsing csv file and then import it on android sqlite

Im new to android. Im still need to learn a lot of things. I know some might report this as duplicate but i guess its different. I want to select files first then import it on android sqlite. I have this code where i can select files and it works properly, after i selected a file it goes like Selected file : "/path/file.csv" something like that. I've also seen some code to import csv file but those files are just stored it assets folder of the project. What i want is to select the file and execute the import so it will be saved on the database. please help.
