How to pass the database for smartphone of my application?

I made my app on the Android Studio and my database in SQLiteBrowser. It runs in the emulator , but when I run my app on the smartphone through USB the database does not exist ( preventing me to do normal tasks such as logging in ). I saw on the Android Advice Monitor that the "data" folder of the emulator contain multiple files and datas, but in the smartphone the folder only exists , but has nothing. Any idea what is ?
