database and raw files on an android device

I have a raw folder in res folder which contains a file. When I run my application on actual device, its not able to get that file. Same is the issue with database.

Do I need to add the file separately onto the device?

Where can I find the database created on my device.

You can able to see your database in DDMS perspective.

Run your application.

windows->open perspective->other-> DDMS

at the right side .three tabs will be there .open File explorer you can find your running application there.just click that.you can find database folder under it.
