Yes, your file wouldn't get copied to the apk this way.
The data directory is the runtime storage area for the app. It only gets created after you install your app on a device/emulator.
So, this kind of packaging your data would never work.
One way to package your data is by putting it into the assets folder. However, if you would like to edit/change the file once the application is installed, this method also would not work for your situation.
But, if you just want a read only version of this file, putting it into assets folder would work fine.
