Hello In my android application when the user reinstall the app again i would like to delete the existing database and create a fresh new one.
How could i know that the user is reinstalling the app or is quering for the updates request.
How could i delete a file in raw folder?
Please share your valuable suggestions.
Thanks in advance:)

If by "reinstall", you mean "uninstall and reinstall", your existing database will be deleted during the uninstall process, assuming it resides in the normal database location (i.e., not on external storage).

You don't.

In Android? You don't. Resources cannot be modified or removed at runtime.
Reinstalling application deletes all data for the application. If you mean reinstalling is upgrading then you can observe the new version number in the SQLiteOpenHelper.onUpgrade() method.
To delete the database file, it is explained here (Database Delete Android).
